Product details
Overview
1N6296AHE3/51 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 105–116 V breakdown voltage (VBR), 94.0 V maximum working voltage (VWM), 152 V clamping voltage at 9.9 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - deployed in automotive engine control units to safeguard microcontrollers against load-dump transients.
For engineers reviewing the 1N6296AHE3/51 datasheet, 1N6296AHE3/51 pinout, 1N6296AHE3/51 application, or 1N6296AHE3/51 equivalent, key selection criteria include its uni-directional polarity, 1.5KE package thermal resistance (RθJL = 15.4 °C/W), low 1.0 µA max reverse leakage at VWM, 175 °C max junction temperature, and compliance with JESD 201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ) up to 94.0 V, then rapidly avalanches into low-impedance conduction when transient voltage exceeds 105 V (min VBR). Its glass-passivated junction enables sub-nanosecond response time (<1 ns) and stable clamping performance across -55 °C to +175 °C.
The device uses a single PN junction in DO-201AD (Case Style 1.5KE) package with axial leads, rated for 200 A non-repetitive forward surge (8.3 ms half-sine), 6.5 W steady-state power dissipation at TL = 75 °C, and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - defines minimum voltage at which avalanche conduction begins reliably at 1 mA test current; ensures robust margin above 94.0 V operating rail |
| VWM | 94.0 V - maximum continuous reverse voltage before significant leakage; sets upper limit for safe DC bias in protected circuits |
| VC @ IPPM | 152 V at 9.9 A - clamping voltage during 10/1000 µs transient; determines worst-case stress on downstream ICs during surge events |
| PPPM | 1500 W - peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Pulse 5a (load dump) |
| IFSM | 200 A - non-repetitive forward surge rating; enables survival of short-duration inrush or fault currents without bond-wire failure |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments with minimal derating |
| Leakage @ VWM | ≤1.0 µA - ultra-low reverse leakage ensures negligible standby power loss and no signal integrity impact on high-impedance nodes |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards; E3 suffix indicates RoHS-compliant commercial grade, HE3 suffix adds AEC-Q101 qualification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge conduction | Connected to protected line side; must be routed with low-inductance path to ground reference for effective clamping |
| Cathode | Reverse-biased terminal; marked by color band | Connected to system ground or low-impedance return; color band identifies polarity for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface degradation mechanisms seen in silicon nitride-passivated devices |
| 1500 W peak pulse power (10/1000 µs) | Supports automotive load-dump protection per ISO 7637-2 without external series impedance or staged clamping networks |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias HAST, and mechanical shock - required for powertrain and chassis ECUs |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD or inductive switching), reducing stress on protected MOSFET gates |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high-temperature/humidity bias, eliminating latent field failures in sealed automotive modules |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|

Use Scenario: Suppressing commutation spikes generated by brushed DC motors in washing machine control boards during direction reversal. IC Role / Device Role: Clamp diode across motor terminals, diverting inductive energy away from H-bridge MOSFETs and MCU GPIOs. Use Value: 200 A IFSM rating prevents single-pulse failure during stall conditions; 175 °C TJ max accommodates enclosed thermal environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 | Lower PPPM (600 W), smaller SMB package (RθJA = 110 °C/W), same VBR range (105–116 V) | Not AEC-Q101 qualified; limited to commercial/industrial use where space constraints outweigh power handling needs | Select when board area is critical and surge energy is ≤600 W; verify thermal design due to higher junction-to-ambient resistance |
| 1.5KE110AHE3_A | Identical electrical specs and AEC-Q101 qualification; differs only in packaging format (tape-and-reel vs. bulk/ammopack) | No functional difference; identical performance in circuit; used interchangeably where form factor permits | Choose based on assembly method - 1N6296AHE3/51 is optimized for automated pick-and-place with 13" reel delivery |
Compared with SMBJ110A-E3/52, the 1N6296AHE3/51 delivers 2.5× higher surge power handling and automotive qualification, while 1.5KE110AHE3_A offers identical protection with alternate packaging - making the 1N6296AHE3/51 optimal for high-reliability, high-energy automotive and industrial deployments requiring verified AEC-Q101 compliance.

FAQ
What is the breakdown voltage tolerance for the 1N6296AHE3/51?
The 1N6296AHE3/51 has a specified breakdown voltage range of 105 V to 116 V at 1 mA test current, representing a ±5% tolerance around the nominal 110 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 24 V systems where overvoltage margins are constrained.
Is the 1N6296AHE3/51 suitable for bi-directional transient protection?
No, the 1N6296AHE3/51 is strictly a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional protection, Vishay offers the 1N6296CA variant (with "CA" suffix); using the 1N6296AHE3/51 in AC or floating applications would result in forward conduction during negative half-cycles and potential device failure.
What is the maximum allowable lead temperature during soldering for the 1N6296AHE3/51?
The 1N6296AHE3/51 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for reliable wetting. Reflow profiles must stay within JEDEC Level 2a limits; exceeding 275 °C risks epoxy cracking or junction damage due to thermal mismatch.
How does the 1N6296AHE3/51 perform under repeated surge stress?
The 1N6296AHE3/51 is rated for repetitive surges at 0.01% duty cycle (1 pulse per 10,000 cycles), validated per its 1500 W peak pulse power spec. Under this condition, junction temperature rise remains within safe limits thanks to RθJL = 15.4 °C/W. Continuous repetition beyond spec invalidates clamping consistency and may cause parametric drift or catastrophic failure.
Does the 1N6296AHE3/51 meet automotive qualification standards?
Yes, the HE3 suffix confirms AEC-Q101 qualification for the 1N6296AHE3/51, covering stress tests including temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock. This makes it suitable for powertrain, chassis, and body electronics where zero-defect reliability is mandated.
