Product details
Overview
1N6292A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC 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 in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6292A-E3/54 datasheet, 1N6292A-E3/54 pinout, 1N6292A-E3/54 application, or 1N6292A-E3/54 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct alternative part comparisons for ESD and lightning transient suppression design.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
It delivers 1500 W peak pulse power handling with 10/1000 µs waveform, supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and maintains operation across –55 °C to +175 °C junction temperature range - enabling use in under-hood automotive modules and industrial PLC I/O terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 64.1 V maximum - ensures no conduction during normal 60 V DC rail operation, minimizing standby leakage |
| VC @ IPPM | 104 V at 14.6 A - limits protected circuit voltage to safe level during 1500 W transient event |
| PPPM | 1500 W with 10/1000 µs waveform - sustains high-energy surges common in automotive load-dump and inductive switching |
| IFSM | 200 A peak forward surge (8.3 ms) - withstands high-current transients without bond-wire fusing |
| TJ max. | +175 °C - enables placement near heat-generating components in engine control units and motor drives |
| RθJA | 75 °C/W - requires minimal heatsinking for continuous 6.5 W dissipation at lead temperature ≤75 °C |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body with matte tin-plated leads; RoHS-compliant per JESD 201 Class 1A whisker test; UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line (e.g., 60 V supply rail) to clamp overvoltage to VC |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and low parameter drift over 1000-hour life testing |
| 1500 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) up to 120 V/1500 W without degradation |
| Sub-nanosecond response time | Clamps transients within 1 ns - faster than MOVs or polymer-based protectors, preserving signal integrity |
| AEC-Q101 qualification option | HE3 suffix variants available for automotive-grade reliability; 1N6292A-E3/54 is commercial grade |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., EFT bursts per IEC 61000-4-4) |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V/24 V vehicle battery feed to engine control unit exposed to ISO 7637-2 load dump pulses up to 120 V. IC Role / Device Role / Timing Role: Unidirectional shunt clamping device placed between power rail and chassis ground.

IC Role / Device Role / Timing Role: Bidirectional-capable but used unidirectionally across loop supply and return to suppress common-mode transients. Use Value: Clamps induced spikes before they reach precision op-amps and ADC front-ends, maintaining measurement accuracy. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |
Use Scenario: –48 V DC distribution in telecom central office equipment vulnerable to AC-line coupling and grounding faults. IC Role / Device Role / Timing Role: Cathode tied to –48 V rail, anode to system ground - clamps positive-going transients to safe levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A | DO-214AA package; 70 V VWM, 113 V VC @ 13.3 A; 600 W PPPM | Lower power rating suits space-constrained consumer electronics; not suitable for automotive load dump | Select SMBJ70A only for compact PCB layouts where 600 W surge margin suffices and leaded mounting is impractical |
| 1.5KE75A | Same DO-201AD package and identical electrical specs; differs only in packaging format (tape/reel vs. bulk) | No functional difference - 1.5KE75A is the JEDEC-standardized designation for same die and construction | Choose 1.5KE75A for standard reel delivery; 1N6292A-E3/54 indicates specific tape-and-reel configuration (1400 pcs/13″ reel) |
Compared with SMBJ70A, 1N6292A-E3/54 provides 2.5× higher surge power handling and superior thermal robustness for under-hood environments; compared with 1.5KE75A, it specifies exact packaging logistics (E3/54 = RoHS-compliant, 13″ paper tape, 1400-unit reel) without electrical deviation.

FAQ
What is the breakdown voltage tolerance for 1N6292A-E3/54?
The 1N6292A-E3/54 has a specified breakdown voltage range of 71.3 V to 78.8 V at 1 mA test current, corresponding to a ±5 % tolerance around the nominal 75 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in safety-critical designs.
Is 1N6292A-E3/54 suitable for bidirectional transient suppression?
No - 1N6292A-E3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional operation, Vishay offers the 1N6292CA variant (or 1.5KE75CA), which clamps symmetrically in both polarities and lacks polarity marking. Using 1N6292A-E3/54 in bidirectional circuits risks forward conduction during negative transients.
What is the maximum operating temperature for 1N6292A-E3/54?
The 1N6292A-E3/54 has a maximum junction temperature (TJ) of +175 °C and operates from –55 °C to +175 °C. Its thermal resistance junction-to-lead (RθJL) is 15.4 °C/W, allowing reliable operation in high-ambient environments such as engine compartments when mounted with adequate copper pour or short lead lengths.
How does the clamping voltage of 1N6292A-E3/54 compare to its breakdown voltage?
The 1N6292A-E3/54 clamps at 104 V (VC) when subjected to its rated 14.6 A peak pulse current (IPPM), which is approximately 35 % above its minimum breakdown voltage (71.3 V). This VC – VBR margin reflects the device's low dynamic impedance and ensures protected circuits remain below absolute maximum ratings during surge events.
Does 1N6292A-E3/54 meet automotive qualification standards?
The base 1N6292A-E3/54 is commercial-grade and not AEC-Q101 qualified. However, Vishay offers the 1N6292AHE3_B variant (with HE3 suffix and revision code B), which is fully AEC-Q101 qualified for automotive applications. Engineers requiring automotive compliance must specify the HE3_B version - the E3/54 suffix denotes RoHS compliance and packaging only, not qualification level.
