Product details
Overview
1N6295AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in power rails and signal lines. It features a 95.0 V to 105 V breakdown voltage (VBR), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage at 10.9 A peak pulse current, 1500 W peak pulse power rating with 10/1000 µs waveform, and operates across –55 °C to +175 °C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6295AHE3_B/C datasheet, 1N6295AHE3_B/C pinout, 1N6295AHE3_B/C application, or 1N6295AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, JEDEC 1.5KE package dimensions, and direct alternative part comparisons for robust ESD and surge protection design-in.
Technical Context
This unidirectional TVS diode uses a glass passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs pulse waveform with 0.01 % duty cycle, and it exhibits a temperature coefficient of VBR of +0.106 %/°C.
The device supports 200 A non-repetitive forward surge current (IFSM) at 8.3 ms half-sine, dissipates 6.5 W on infinite heatsink at TL = 75 °C, and maintains 1.0 µA max reverse leakage at VWM. Its RθJA is 75 °C/W and RθJL is 15.4 °C/W, confirming suitability for lead-mounted PCB-level surge suppression without active cooling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85AHE3/52 | Lower PPPM (600 W), smaller SMB package (surface-mount), VBR = 94.4–104.4 V, VC = 137 V @ 4.4 A | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs, not under-hood automotive | Select when board area is limited and surge energy is ≤600 W; requires re-layout due to SMD footprint |
| 1.5KE100AHE3_A | Same 1.5KE package and core specs, but HE3_A revision lacks AEC-Q101 certification per Doc. 88301 Note (2) | Approved for commercial/industrial use only; excluded from automotive production BOMs requiring Q101 traceability | Acceptable for cost-sensitive industrial controls where automotive qualification is not mandated |
Compared with 1N6295AHE3_B/C, SMBJ85AHE3/52 trades peak power and qualification for compactness, while 1.5KE100AHE3_A matches form/fit/function but omits AEC-Q101 validation - making 1N6295AHE3_B/C the sole choice for automotive Tier-1 power rail protection requiring full compliance traceability.

FAQ
What is the clamping voltage of the 1N6295AHE3_B/C and how is it measured?
The 1N6295AHE3_B/C has a maximum clamping voltage (VC) of 137 V, measured at its rated peak pulse current (IPPM) of 10.9 A using a standardized 10/1000 µs double-exponential waveform. This value reflects the voltage seen across the 1N6295AHE3_B/C terminals during worst-case surge events and is critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1N6295AHE3_B/C suitable for automotive applications?
Yes - the 1N6295AHE3_B/C carries the HE3_B suffix, indicating full AEC-Q101 qualification per Vishay Document 88301 Note (2). It has undergone temperature cycling, highly accelerated life testing (HALT), and ESD validation required for under-hood and powertrain modules, making it appropriate for production automotive use where reliability is mandated.
How does the 1N6295AHE3_B/C differ from the standard 1N6295A?
The 1N6295AHE3_B/C adds RoHS compliance (E3), AEC-Q101 qualification (HE3_B), and enhanced whisker resistance (JESD 201 Class 2) versus the base 1N6295A. The "_B/C" denotes tape-and-reel packaging (1400 pcs per 13" reel), whereas the base part lacks automotive qualification and may ship in bulk or different packaging formats.
What is the thermal resistance of the 1N6295AHE3_B/C and why does it matter?
The 1N6295AHE3_B/C has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15.4 °C/W. These values determine how effectively heat from surge dissipation transfers to the PCB and ambient air - critical for sustaining repeated 1500 W pulses without exceeding the 175 °C maximum junction temperature.
Can the 1N6295AHE3_B/C be used in bidirectional configurations?
No - the 1N6295AHE3_B/C is a unidirectional TVS diode, identified by its cathode band marking and specified VBR/VWM values for reverse-bias operation only. For bidirectional protection, Vishay offers the 1N6295CAHE3_B/C variant (not this part), which provides symmetrical clamping in both polarities and no polarity marking.
