Product details
Overview
1N6295AHE3_A/C from Vishay General Semiconductor is a unidirectional 1500 W Transient Voltage Suppressor (TVS) diode with a breakdown voltage range of 95.0 V to 105 V, clamping voltage of 137 V at 10.9 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability. It features glass passivated junction, RoHS-compliant matte tin-plated leads, and is designed for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges.
For engineers reviewing the 1N6295AHE3_A/C datasheet, 1N6295AHE3_A/C pinout, 1N6295AHE3_A/C application, or 1N6295AHE3_A/C equivalent, this part serves as a high-power, fast-response (≤1 ns), low-clamping-voltage surge protector in automotive powertrain control units, industrial motor drives, telecom interface protection, and DC bus overvoltage suppression circuits.
Technical Context
This unidirectional TVS diode operates with a 10/1000 μs waveform, delivering 1500 W peak pulse power and clamping transients within nanoseconds. Its 137 V clamping voltage at 10.9 A ensures robust protection for 100 V-class systems while maintaining low incremental surge resistance and excellent thermal stability up to 175 °C junction temperature.
The device uses a molded epoxy case (Case Style 1.5KE) with UL 94 V-0 flammability rating and meets JESD 201 Class 2 whisker test requirements via HE3 suffix. Polarity is marked by a cathode band; it supports 8.3 ms half-sine surge current up to 200 A and exhibits a temperature coefficient of 0.106 %/°C for VBR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower PPPM (600 W), smaller SMB package, 100 V VBR min, 165 V VC @ 3.6 A | Not AEC-Q101 qualified; suited for space-constrained consumer electronics, not automotive under-hood use. | Select when board area is limited and surge energy is ≤600 W; verify thermal derating for continuous operation. |
| 1.5KE100AHE3_A/C | Identical electrical specs and AEC-Q101 qualification; same 1.5KE package, but base P/N uses 1.5KE prefix instead of 1N6295A | No functional difference - dual-marking variant issued by Vishay for same die and assembly process. | Direct form-fit-function replacement; interchange permitted per Vishay's cross-reference documentation. |
Compared with SMBJ100A, the 1N6295AHE3_A/C delivers 2.5× higher surge power handling and automotive qualification, while 1.5KE100AHE3_A/C offers identical performance in an alternate part-numbering scheme-making it a seamless drop-in option where legacy BOMs specify the 1.5KE prefix.

FAQ
What is the clamping voltage of the 1N6295AHE3_A/C at its rated peak pulse current?
The 1N6295AHE3_A/C has a maximum clamping voltage (VC) of 137 V at its rated peak pulse current (IPPM) of 10.9 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures predictable voltage limiting during surge events, protecting downstream 100 V-rated components without exceeding their absolute maximum ratings. The 1N6295AHE3_A/C maintains this clamping performance across its full operating temperature range.
Is the 1N6295AHE3_A/C qualified for automotive applications?
Yes, the 1N6295AHE3_A/C carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It is tested for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life, making it suitable for under-hood and powertrain applications. The 1N6295AHE3_A/C is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the 1.5KE series, supporting deployment in engine control units and battery management systems.
What is the standoff voltage (VWM) of the 1N6295AHE3_A/C, and how does it relate to system design?
The 1N6295AHE3_A/C has a maximum working peak reverse voltage (VWM) of 85.5 V, meaning it remains non-conductive below this threshold during normal operation. This allows integration into 72–80 V nominal DC systems (e.g., 24 V commercial vehicles or 48 V mild-hybrid architectures) with sufficient margin to avoid leakage-induced power loss or false triggering. Designers must ensure system ripple and transients stay below 85.5 V to maintain reliable blocking behavior before clamping activates.
How does the thermal resistance of the 1N6295AHE3_A/C affect PCB layout decisions?
The 1N6295AHE3_A/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, which means effective heat dissipation relies heavily on copper pour area and lead thermal mass. For repeated surge events, designers should use ≥10 mm² of 2 oz copper connected to both leads and avoid narrow traces. The 1N6295AHE3_A/C's RθJA of 75 °C/W confirms that ambient cooling alone is insufficient-thermal vias and ground-plane coupling are essential to sustain its 175 °C maximum junction temperature rating.
Can the 1N6295AHE3_A/C be used in bidirectional configurations?
No, the 1N6295AHE3_A/C is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1.5KE100CA). Using the 1N6295AHE3_A/C in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection, select a verified CA-part such as 1N6295CAHE3_A/C or 1.5KE100CAHE3_A/C, which are electrically symmetric and lack polarity marking.
