[Remarks] *1: Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out. *2: The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading. *3: Use the designated transformer power supply circuit shown in the figure below for allowable load shorted time and output noise voltage measurement. *4: Use the standby pin (pin 1) so that the applied voltage never exceeds the maximum rating. The power amplifier is turned on by applying +2.5V to +5.5V to the standby pin (pin 1). *5: The -Pre VCC (pin 6) must be at the lowest level under any circumstances so that the reverse-bias current does not flow. * Thermal design must be implemented based on the conditions under which the customer's end products are expected to operate on the market. * The weight of hybrid IC alone: 15g Package dimensions (lengthxwidthxheight): 502mmx247mmx282mm

[Thermal Design Example for STK404-230-E (RL=6)] The thermal resistance, c-a, of the heat sink for total power dissipation, Pd, within the hybrid IC is determined as follows. Condition 1: The hybrid IC substrate temperature, Tc, must not exceed 125C. Pd x c-a + Ta < 125C ................................................................................................. (1) Ta: Guaranteed ambient temperature for the end product Condition 2: The junction temperature, Tj, of each power transistor must not exceed 150C. Pd x c-a + Pd/N x j-c + Ta < 150C .......................................................................... (2) N: Number of power transistors j-c: Thermal resistance per power transistor However, the power dissipation, Pd, for the power transistors shall be allocated equally among the number of power transistors. The following inequalities result from solving equations (1) and (2) for c-a. c-a < (125 - Ta)/Pd ...................................................................................................... (1)' c-a < (150 - Ta)/Pd - j-c/N ........................................................................................ (2)' Values that satisfy these two inequalities at the same time represent the required heat sink thermal resistance. When the following specifications have been stipulated, the required heat sink thermal resistance can be determined from formulas (1)' and (2)'. * Supply voltage VCC * Load resistance RL * Guaranteed ambient temperature Ta [Example] When the IC supply voltage, VCC=44V and RL is 6, the total power dissipation, Pd, within the hybrid IC, will be a maximum of 64W at 1kHz for a continuous sine wave signal according to the Pd-Po characteristics. For the music signals normally handled by audio amplifiers, a value of 1/8PO max (PO=12.5W) is generally used for Pd as an estimate of the power dissipation based on the type of continuous signal. (Note that the factor used may differ depending on the safety standard used.) This is: Pd 45W (when 1/8PO max. = 12.5W, PO max. = 100W).
The number of power transistors in audio amplifier block of these hybrid ICs, N, is 2, and the thermal resistance per transistor, j-c, is 1.6C/W. Therefore, the required heat sink thermal resistance for a guranteed ambient temperature, Ta, of 50C will be as follows. From formula (1)' c-a < (125 - 50)/45.0 < 1.66 From formula (2)' c-a < (150 - 50)/45.0 - 1.6/4 < 1.42 Therefore, the value of 1.42C/W, which satisfies both of these formulae, is the required thermal resistance of the heat sink. Note that this thermal design example assumes the use of a constant-voltage power supply, and is therefore not a verified design for any particular user's end product.

Overcurrent Protection Circuit
Overcurrent protection is activated if VOC 0.5V (typ) is applied to OC (#9). The HIC shuts down (latch mode) and the state of the error pin switches from high to low. The (open collector output) latch mode is cleared by setting the pin to the ground level.
