Product details
Overview
1N6293AHE3/51 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 77.9 V to 86.1 V breakdown voltage range at 1 mA test current, 70.1 V maximum stand-off voltage, 113 V clamping voltage at 13.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the 1N6293AHE3/51 datasheet, 1N6293AHE3/51 pinout, 1N6293AHE3/51 application, or 1N6293AHE3/51 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 0.105 %/°C temperature coefficient of VBR, RoHS-compliant matte tin-plated leads, and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a fast-acting shunt clamp, entering avalanche conduction within <1 ns when transient voltage exceeds its breakdown threshold. Its glass-passivated silicon junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and repeatable clamping performance under repetitive 10/1000 µs pulses at 0.01 % duty cycle.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), supports 6.5 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature, and exhibits 75 °C/W junction-to-ambient thermal resistance - confirming suitability for surface-mount PCB layouts with moderate copper pour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 77.9 V min to 86.1 V max at 1 mA - defines precise clamping onset threshold for reliable overvoltage detection |
| Stand-off Voltage VWM | 70.1 V max - ensures no conduction during normal 60 V–70 V DC rail operation |
| Clamping Voltage VC | 113 V at 13.3 A IPPM - limits transient voltage seen by downstream ICs to safe level |
| Peak Pulse Power PPPM | 1500 W with 10/1000 µs waveform - sustains high-energy surges without failure |
| Junction Temperature Range | −55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments |
| Temperature Coefficient of VBR | +0.105 %/°C - allows accurate derating of breakdown voltage across operating temperature range |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |
Pinout & Package
1N6293AHE3/51 uses the industry-standard Case Style 1.5KE DO-201AD package: axial-leaded, molded epoxy body with cathode band marking. Leads are matte tin-plated, compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected circuit ground or low-side return path |
| Cathode | Current exit point during reverse-biased clamping | Connected to line being protected (e.g., 48 V supply rail); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable electrical parameters and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Handles high-energy transients from inductive load switching or ESD events without degradation |
| AEC-Q101 qualification | Validates robustness for automotive applications including engine control units and body electronics |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot during clamping - critical for protecting 75 V-rated MOSFETs and gate drivers |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - required for automotive production |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), 70 V VWM, 113 V VC at 5.3 A | Better suited for space-constrained PCBs; lower energy handling limits use in lower-risk environments | Select when board area is constrained and surge threat level is moderate (e.g., consumer IoT vs. automotive under-hood) |
| 1.5KE82A-E3/54 | Same electrical specs and DO-201AD package; differs only in packaging format (tape-and-reel vs. bulk/heatsink-optimized delivery) | No functional difference - identical performance and footprint; diverges only in logistics and traceability | Choose for standard automated assembly lines requiring 13" tape-and-reel; 1N6293AHE3/51 preferred for AEC-Q101 traceability and Class 2 whisker compliance |
Compared with SMBJ70A, 1N6293AHE3/51 delivers 2.5× higher surge energy capacity and automotive qualification; versus 1.5KE82A-E3/54, it adds documented AEC-Q101 validation and enhanced whisker resistance - critical for Tier 1 automotive production programs.

FAQ
What is the exact breakdown voltage range for 1N6293AHE3/51?
The 1N6293AHE3/51 has a guaranteed breakdown voltage (VBR) range of 77.9 V to 86.1 V measured at 1 mA test current, per Vishay Document 88301. This ±5 % tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage design margins in 48 V and 60 V systems.
Is 1N6293AHE3/51 suitable for automotive applications?
Yes, 1N6293AHE3/51 is AEC-Q101 qualified per Vishay documentation and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker resistance. Its −55 °C to +175 °C operating range, 1500 W surge rating, and glass-passivated junction make it appropriate for engine control, body electronics, and ADAS power rail protection.
What does the "HE3/51" suffix mean in 1N6293AHE3/51?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/51" specifies the packaging option - 51 mm tape pitch on 13-inch reels with 1400 units per reel, optimized for high-volume SMT placement equipment.
How does 1N6293AHE3/51 compare to 1.5KE82A in electrical performance?
1N6293AHE3/51 and 1.5KE82A share identical electrical specifications: same VBR, VWM, VC, PPPM, and thermal ratings. The distinction lies in qualification - 1N6293AHE3/51 explicitly carries AEC-Q101 certification and Class 2 whisker testing, whereas 1.5KE82A-E3 variants may lack full automotive validation.
What is the maximum clamping voltage of 1N6293AHE3/51 under surge conditions?
The maximum clamping voltage (VC) of 1N6293AHE3/51 is 113 V at 13.3 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuits during worst-case transient events.
