Product details
Overview
1N6293AHE3_B/C 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 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V maximum working voltage (VWM), 113 V clamping voltage at 13.3 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across -55 °C to +175 °C junction temperature. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6293AHE3_B/C datasheet, 1N6293AHE3_B/C pinout, 1N6293AHE3_B/C application, or 1N6293AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant matte tin plating, and JEDEC 1.5KE package mechanical data - all confirmed from Vishay Document #88301 (Rev. 09-Aug-2022).
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 waveform with 0.01% duty cycle, and it maintains stable performance up to 175 °C junction temperature.
The device complies with JESD 22-B106 (solder dip ≤275 °C for 10 s), meets UL 94 V-0 flammability rating, and supports AEC-Q101 qualification for automotive use. The HE3 suffix denotes RoHS compliance and AEC-Q101 qualification; "B/C" indicates revision level and packaging format (13" paper tape & reel, 1400 pcs).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A-E3/52 | Lower PPPM (600 W), smaller SMB package, VBR = 77.8–86.0 V, VC = 115 V @ 5.2 A | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs, not under-hood automotive | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5KE82AHE3_A/H | Same electrical specs but older revision (A/H); identical 1.5KE package, same AEC-Q101 qualification, no functional difference | No application difference - fully interchangeable in new designs and legacy BOM refreshes | Prefer 1N6293AHE3_B/C for latest process control and traceability; use A/H only for continuity in existing production |
Compared with SMBJ70A-E3/52, the 1N6293AHE3_B/C delivers 2.5× higher surge power handling and automotive qualification; compared with 1.5KE82AHE3_A/H, it offers updated manufacturing traceability and enhanced whisker resistance (Class 2 vs Class 1A), supporting longer product lifecycle assurance.

FAQ
What is the clamping voltage of the 1N6293AHE3_B/C at its rated peak pulse current?
The 1N6293AHE3_B/C clamps to 113 V at its specified peak pulse current of 13.3 A under a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees predictable overvoltage limiting for downstream components such as 100 V-rated MOSFETs or automotive-grade microcontrollers. The 1N6293AHE3_B/C achieves this with minimal voltage overshoot due to its sub-nanosecond response time.
Is the 1N6293AHE3_B/C qualified for automotive applications?
Yes, the 1N6293AHE3_B/C is AEC-Q101 qualified, as confirmed in Vishay Document #88301 (Rev. 09-Aug-2022), footnote (2). This qualification covers high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - making the 1N6293AHE3_B/C suitable for engine control modules, body controllers, and ADAS power supplies where reliability is mission-critical.
What does the "HE3_B/C" suffix mean in 1N6293AHE3_B/C?
The "HE3" suffix indicates RoHS compliance and AEC-Q101 qualification per JESD 201 Class 2 whisker resistance. "B/C" specifies the revision code and packaging format: "B" denotes the manufacturing revision level, and "C" identifies the preferred package code for 13-inch paper tape and reel (1400 pieces per reel), as defined in Vishay's ordering information table.
How does the 1N6293AHE3_B/C compare to standard Zener diodes in surge protection?
Unlike standard Zeners, the 1N6293AHE3_B/C is engineered for high-energy transient suppression: it delivers 1500 W peak pulse power (vs. typically <5 W for Zeners), responds in <1 ns (vs. ~10–100 ns), and sustains repetitive surges without degradation. Its glass passivated junction and rugged 1.5KE package make the 1N6293AHE3_B/C suitable for industrial and automotive environments where Zeners would fail catastrophically.
What is the thermal resistance from junction to lead (RθJL) for the 1N6293AHE3_B/C?
The 1N6293AHE3_B/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, per Vishay Document #88301. This low value enables effective heat transfer to PCB copper pours or heatsinks, allowing the 1N6293AHE3_B/C to maintain safe junction temperatures even during repeated surge events - critical for automotive and industrial applications with limited airflow.
