Product details
Overview
1N6290AHE3/51 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 58.9 V to 65.1 V breakdown voltage (VBR) at 1 mA, 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 17.6 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 1N6290AHE3/51 datasheet, 1N6290AHE3/51 pinout, 1N6290AHE3/51 application, or 1N6290AHE3/51 equivalent, this device is selected for high-energy transient suppression where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.31), AEC-Q101 qualification, and 175 °C junction temperature capability are required in harsh-environment designs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage and repeatable breakdown characteristics across temperature.
The device uses a DO-201AD package with axial leads, optimized for PCB mounting in high-surge environments. Thermal resistance is 15.4 °C/W (junction-to-lead), enabling effective heat dissipation during repetitive transients up to 0.01% duty cycle - critical for automotive load-dump and inductive-switching protection circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/52 | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VC = 93.6 V at 6.4 A | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients in space-constrained designs | Select only if board area is constrained and surge energy remains ≤600 W |
| 1.5KE62AHE3_A | Same electrical specs and DO-201AD package; identical VBR, VWM, VC, and AEC-Q101 qualification | Functionally interchangeable; differs only in packaging code (tape/reel vs. bulk) and revision marking | Drop-in replacement with identical performance and qualification - verify reel quantity code matches production needs |
Compared with SMBJ58A-E3/52, 1N6290AHE3/51 delivers >2.5× peak power handling and tighter clamping for automotive-grade robustness; versus 1.5KE62AHE3_A, it shares identical protection characteristics but differs in ordering suffix - confirming 1N6290AHE3/51 is the preferred variant for tape-and-reel volume procurement.

FAQ
What is the breakdown voltage range of the 1N6290AHE3/51?
The 1N6290AHE3/51 has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at a test current of 1 mA. This range reflects manufacturing tolerance and ensures consistent clamping behavior across production lots. The value is measured per JEDEC standard and verified during 100% production testing. Designers should use the minimum VBR (58.9 V) for worst-case overvoltage margin calculations in safety-critical applications.
Is the 1N6290AHE3/51 suitable for automotive applications?
Yes, the 1N6290AHE3/51 is AEC-Q101 qualified and explicitly rated for automotive use. It meets stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - all defined in the AEC-Q101 standard. Its 175 °C maximum junction temperature and DO-201AD package with matte tin leads support under-hood deployment in engine control units and battery management systems.
What is the clamping voltage of the 1N6290AHE3/51 at its rated peak pulse current?
The 1N6290AHE3/51 exhibits a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 17.6 A, tested with a 10/1000 µs waveform. This clamping voltage represents the upper limit of voltage imposed on the protected circuit during a full-rated surge event. The low VC/VBR ratio (~1.31) confirms efficient energy diversion and minimal stress on downstream components like DC/DC controllers or microcontrollers.
Does the 1N6290AHE3/51 have a bi-directional variant?
No, the 1N6290AHE3/51 is a uni-directional TVS diode. Its cathode is marked with a band and it conducts only in reverse breakdown. For bi-directional protection, Vishay offers the 1N6290CAHE3/51 variant (not 1N6290AHE3/51), which provides symmetrical clamping for AC lines or data buses subject to voltage reversals. The "A" suffix in 1N6290AHE3/51 explicitly denotes uni-directional polarity per Vishay's naming convention.
What package type does the 1N6290AHE3/51 use, and what are its key mechanical properties?
The 1N6290AHE3/51 uses the DO-201AD package: an axial-leaded, molded epoxy case with UL 94 V-0 flammability rating. Lead length is 0.375" (9.5 mm), body diameter is 0.210" (5.3 mm), and lead diameter is 0.042" (1.07 mm). Its thermal resistance is 15.4 °C/W (junction-to-lead), enabling effective heat transfer to PCB copper pours or heatsinks - essential for sustaining repetitive surge events in industrial motor drives.
