Product details
Overview
1N6292A-E3/51 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR) at 1 mA, 64.1 V maximum standoff voltage (VWM), 104 V clamping voltage (VC) at 14.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1N6292A-E3/51 datasheet, 1N6292A-E3/51 pinout, 1N6292A-E3/51 application, or 1N6292A-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating curves, and direct alternatives for circuit protection design-in.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp, activating within <1 ns when transient voltage exceeds its VWM threshold. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling effective suppression of 1500 W pulses without thermal runaway.
The device complies with JEDEC case style 1.5KE, uses matte tin-plated leads solderable per J-STD-002, and supports operation from −55 °C to +175 °C. It is RoHS-compliant (E3 suffix), commercial-grade, and rated for 200 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave.
Key Specifications

FAQ
What is the breakdown voltage tolerance for 1N6292A-E3/51?
The 1N6292A-E3/51 has a specified breakdown voltage range of 71.3 V to 78.8 V at test current IT = 1 mA, corresponding to ±5% tolerance around the nominal 75 V rating. This tight VBR window ensures consistent clamping behavior across production lots and temperature ranges from −55 °C to +175 °C.
Is 1N6292A-E3/51 suitable for bidirectional transient protection?
No, 1N6292A-E3/51 is a unidirectional TVS diode, indicated by the "A" suffix and presence of cathode band marking. For bidirectional protection, Vishay offers the 1N6292CA variant (not 1N6292A-E3/51), which lacks polarity marking and clamps symmetrically in both directions up to ±75 V.
What is the maximum clamping voltage of 1N6292A-E3/51 under surge conditions?
The 1N6292A-E3/51 exhibits a maximum clamping voltage (VC) of 104 V at peak pulse current (IPPM) = 14.6 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does 1N6292A-E3/51 meet automotive qualification standards?
The 1N6292A-E3/51 is commercial-grade and RoHS-compliant (E3 suffix), but it is not AEC-Q101 qualified. For automotive applications requiring AEC-Q101, Vishay offers the 1.5KE75AHE3_B variant - a functionally identical part with added qualification testing and traceability.
How does thermal derating affect 1N6292A-E3/51 power dissipation above 25 °C?
1N6292A-E3/51 has a thermal resistance RθJA of 75 °C/W. Its 6.5 W steady-state power dissipation (PD) must be linearly derated above 25 °C ambient: for every 1 °C rise, PD decreases by 6.5 mW. At 75 °C ambient, maximum allowable PD drops to 3.25 W, per the manufacturer's derating curve (Fig. 5).
