| 1N6461 QPL 500 Watt Axial Leaded TVS Thru 1N6468 TEL:805-498-2111 FAX:805-498-3804 DESCRIPTION The 1N64xx series of transient voltage suppressors are designed to protect military and commercial electronic equipment from overvoltages caused by lightning, ESD, EFT, inductive load switching, and EMP. These devices are constructed using a p-n junction TVS diode in a hermetically sealed, voidless glass package. The hermetically sealed package provides high reliability in harsh environmental conditions. TVS diodes are further characterized by their high surge capability, low operating and clamping voltages, and a theoretically instantaneous response time. This makes them ideal for use as board level protection for sensitive semiconductor components. These devices are DESC QPL qualified to MIL-S-19500/551. FEATURES: * * * * * * 500 Watts Peak Pulse Power (tp = 10/1000s) Voidless hermetically sealed glass package Metallurgically bonded High surge capacity Unidirectional Available in JTX, and JTXV versions per MIL-S-19500/551 MECHANICAL CHARACTERISTICS: * * * Hermetically sealed glass package Tinned copper leads Marking : P/N, date code, logo, & cathode band APPLICATIONS: * * * * * Aerospace & Industrial Electronics Board Level Protection Airborne Systems Shipboard Systems Ground Systems MAXIMUM RATINGS RATING Peak Pulse Power (tp = 10 x 1000s) Operating Temperature Storage Temperature Steady-State Power Dissipation @ TL = 75C (3/8") SYMBOL Ppk Tj Tstg PD VALUE 500 -65 to +175 -65 to +175 3 UNIT Watts C C Watts ELECTRICAL CHARACTERISTICS @ 25C (unless otherwise specified) DEVICE TYPE REVERSE STAND-OFF VOLTAGE VRWM REVERSE LEAKAGE CURRENT IR MINIMUM BREAKDOWN VOLTAGE VBR @ IT TEST CURRENT IT MAXIMUM CLAMPING VOLTAGE Vc @ Ipp PEAK PULSE CURRENT Ipp Tp = 1mS PEAK PULSE CURRENT Ipp Tp = 20S TEMPERATURE COEFFICIENT OF VBR Vz (V) 1N6461 1N6462 1N6463 1N6464 1N6465 1N6466 1N6467 1N6468 5 6 12 15 24 30.5 40.3 51.6 (A) 3000 2500 500 500 50 3 2 2 (V) 5.6 6.5 13.6 16.4 27.0 33.0 43.7 54.0 (mA) 25 20 5 5 2 1 1 1 (V) 9.0 11.0 22.6 26.5 41.4 47.5 63.5 78.5 (A) 56 46 22 19 12 11 8 6 (A) 315 258 125 107 69 63 45 35 % /C 0.040 0.040 0.050 0.060 0.084 0.093 0.094 0.096 (c) 1997 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 1N6461 QPL 500 Watt Axial Leaded TVS Thru 1N6468 TEL:805-498-2111 FAX:805-498-3804 PEAK PULSE POWER vs. PULSE TIME 100 10x1000s IMPULSE WAVEFORM Ppp - Peak Pulse Power (kW) 10 1 0.1 0.1 1 10 100 1000 10000 Pulse Duration (us) STEADY STATE DERATING CHARACTERISTICS FOR FREE AIR MOUNTING 2.5 PULSE DERATING CURVE 100 Pp or Ipp in % of max ratings Pulse conditions as defined by 10 X 1000us impulse waveform 2 1.5 MAX.
