Product details
Overview
1N6275HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 15 V breakdown voltage (VBR min = 14.3 V, max = 15.8 V at 1.0 mA), 12.8 V stand-off voltage (VWM), 21.2 V clamping voltage (VC) at 70.8 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 industrial power supplies and automotive control modules.
For engineers reviewing the 1N6275HE3/73 datasheet, 1N6275HE3/73 pinout, 1N6275HE3/73 application, or 1N6275HE3/73 equivalent, this part delivers verified AEC-Q101 qualification, low incremental surge resistance, fast sub-nanosecond response, glass-passivated junction reliability, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches into low-impedance conduction, diverting surge current away from downstream circuitry. Its 10/1000 µs waveform rating reflects standardized lightning-surge immunity testing per R.E.A. P.E. 60 and IEC 61000-4-5.
Thermal design is constrained by RθJA = 75 °C/W and RθJL = 15.4 °C/W, with maximum junction temperature of +175 °C and derating above 25 °C ambient. The device supports 200 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.084 %/°C temperature coefficient of VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 12.8 V - maximum continuous working voltage before leakage exceeds 1.0 µA, ensuring no false triggering in normal operation |
| VC @ IPPM | 21.2 V at 70.8 A - clamped voltage during 1500 W surge, limiting stress on protected ICs to safe levels |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 µs waveform, aligned with IEC 61000-4-5 Level 4 immunity |
| IFSM | 200 A - single-cycle surge current rating (8.3 ms half-sine), supporting robust protection against inductive switch-off events |
| TJ max | +175 °C - extended junction temperature range enabling use in under-hood automotive and high-ambient industrial environments |
| Leakage @ VWM | ≤1.0 µA - ultra-low reverse leakage preserves system efficiency and avoids false trips in battery-powered applications |
Pinout & Package

| Matte tin plated leads (J-STD-002 compliant) | Ensures consistent solder wetting and intermetallic formation in reflow and wave solder processes |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units (ECUs) from load-dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between battery rail and ground, clamping surges >14.3 V before reaching MCU power pins. Use Value: Limits peak voltage to 21.2 V during 70.8 A transients, preventing latch-up or gate oxide rupture in 3.3 V/5 V logic powered from local LDOs. | Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: Line-to-ground TVS on 4–20 mA current loop or 0–10 V analog output lines exposed to ESD and cable discharge events. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) to <21.2 V within 1 ns, preserving ADC reference integrity and avoiding input-stage saturation. |
| DC-DC Converter Input Protection | Telecom Line Card Surge Suppression |
Use Scenario: Input-side protection for isolated 48 V to 5 V flyback converters in telecom power systems. IC Role / Device Role / Timing Role: Primary TVS on bulk input capacitor node, absorbing repetitive surges from upstream distribution bus switching. Use Value: Handles 1500 W pulses at 0.01 % duty cycle without degradation, maintaining VWM = 12.8 V compatibility with 48 V nominal input after voltage divider scaling. | Use Scenario: Secondary-level protection on Ethernet PHY power rails (e.g., 3.3 V bias) in network switches subject to induced lightning surges. IC Role / Device Role / Timing Role: Localized clamping device adjacent to PHY IC, placed before ferrite beads to avoid impedance mismatch during fast transients. Use Value: Delivers 21.2 V clamping at 70.8 A while exhibiting only 0.084 %/°C VBR drift, ensuring stable protection across -40 °C to +85 °C operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower 600 W PPPM, SMA package (smaller footprint), VC = 24.4 V @ 24.5 A | Targeted at space-constrained consumer electronics; insufficient for 1500 W industrial surge requirements | Select 1N6275HE3/73 when full 1500 W IEC 61000-4-5 compliance and DO-201AD mechanical robustness are required. |
| 1.5KE15A | Same electrical specs and DO-201AD package, but commercial-grade (non-AEC-Q101) and E3 suffix only (no HE3 whisker rating) | Lacks automotive qualification and JESD 201 Class 2 whisker resistance; unsuitable for mission-critical vehicle systems | Choose 1N6275HE3/73 for automotive or high-reliability industrial use where AEC-Q101 and enhanced whisker resistance are mandatory. |
Compared with SMBJ15A and 1.5KE15A, the 1N6275HE3/73 uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance in the proven DO-201AD package - making it the only option among the three qualified for under-hood automotive deployment with full IEC 61000-4-5 Level 4 immunity.

FAQ
What is the breakdown voltage tolerance of the 1N6275HE3/73?
The 1N6275HE3/73 has a specified breakdown voltage range of 14.3 V to 15.8 V at 1.0 mA test current, representing ±5.3 % tolerance around the nominal 15 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting voltage-sensitive 12 V system components without premature conduction.
Is the 1N6275HE3/73 suitable for automotive applications?
Yes, the 1N6275HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, with validation across high-temperature storage, temperature cycling, and biased humidity testing. Its DO-201AD package, 175 °C max junction temperature, and JESD 201 Class 2 whisker resistance make the 1N6275HE3/73 appropriate for under-hood engine control, body electronics, and ADAS power rail protection.
How does the clamping voltage of the 1N6275HE3/73 compare to its breakdown voltage?
The 1N6275HE3/73 clamps at 21.2 V when subjected to its rated 70.8 A peak pulse current (10/1000 µs), which is 33–49 % above its 14.3–15.8 V breakdown range. This controlled voltage overshoot ensures effective energy diversion while keeping protected circuit nodes below destructive thresholds - a key design parameter confirmed in Vishay's Fig. 7 and Table on page 2 of document 88301.
What is the meaning of the 'HE3' and '/73' suffixes in 1N6275HE3/73?
The 'HE3' suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance (enhanced reliability for high-temperature, high-humidity environments), while '/73' indicates packaging in 73 mm tape-and-reel format per EIA-481 standard. Together, 1N6275HE3/73 identifies the AEC-Q101-qualified, whisker-resistant, surface-mount-ready variant of the 1N6275A TVS diode.
Can the 1N6275HE3/73 be used in bidirectional configurations?
No, the 1N6275HE3/73 is strictly unidirectional - indicated by the 'A' suffix and absence of 'CA' in its designation. Bidirectional variants (e.g., 1N6275CA) exist in the same family but differ in internal structure and marking. Using the 1N6275HE3/73 in bidirectional applications would result in forward conduction during negative transients, potentially causing failure or incorrect protection behavior.
