Product details
Overview
1N6275-E3/54 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 and automotive electronics.
For engineers reviewing the 1N6275-E3/54 datasheet, 1N6275-E3/54 pinout, 1N6275-E3/54 application, or 1N6275-E3/54 equivalent, this device delivers verified transient suppression performance for 12 V–15 V rail protection, with RoHS-compliant matte tin-plated leads, JEDEC 1.5KE case, and commercial-grade reliability per JESD 22-B106 soldering specs.
Technical Context
The 1N6275-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response time (<1 ns) to ESD and lightning-induced transients. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.49).
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with RθJA = 75 °C/W and RθJL = 15.4 °C/W, allowing direct PCB-mount use without heatsinking for short-duration pulses. It is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) and 6.5 W steady-state power dissipation at TL = 75 °C.
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 triggering above normal operating voltage |
| VWM | 12.8 V - maximum continuous reverse working voltage; ensures no conduction during nominal 12 V system operation |
| VC @ IPPM | 21.2 V at 70.8 A - clamped voltage seen by protected circuit during full 1500 W transient event |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity suitable for IEC 61000-4-5 Level 3/4 compliance |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-current inductive switch-off surges without failure |
| TJ range | –55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Package | JEDEC 1.5KE molded epoxy case - industry-standard axial leaded package with UL 94 V-0 flammability rating |
Pinout & Package
Package: JEDEC 1.5KE axial-leaded molded epoxy case (Case Style 1.5KE), 0.375" (9.5 mm) lead length, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return in unidirectional clamp configuration |
| Cathode (banded end) | Avalanche breakdown node / protected line connection | Connected to line being protected (e.g., 12 V rail); conducts when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 combination wave surges up to 4 kV/2 Ω |
| Sub-nanosecond response time | Clamps transients before sensitive downstream components experience damaging overvoltage |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and JESD 22-B106 solder dip (275 °C, 10 s) |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage exposure to protected ICs while maintaining margin above VWM |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs and body control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary shunt TVS placed across input rail to clamp transients before LDOs and microcontrollers. Use Value: Withstands 200 A surge and clamps to 21.2 V, keeping downstream 3.3 V/5 V logic supplies within safe operating area. |
Use Scenario: Safeguarding analog front-ends of pressure/temperature sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Unidirectional TVS on sensor supply line (VS) and output line (e.g., 4–20 mA loop) to suppress EFT and cable-coupled noise. Use Value: 12.8 V VWM avoids false triggering during normal 12 V operation; 21.2 V VC prevents op-amp saturation or ADC damage. |
| Telecom DC Power Input Protection | Consumer Equipment AC/DC Adapter Output Protection |

IC Role / Device Role / Timing Role: First-line TVS on primary DC input, coordinated with upstream fuses and secondary filtering. Use Value: 1500 W rating handles multi-kV induced surges; UL 94 V-0 package meets safety requirements for enclosed telecom gear. |
Use Scenario: Adding transient immunity to 12 V outputs of wall adapters powering smart home hubs, set-top boxes, and audio amplifiers. IC Role / Device Role / Timing Role: Low-cost, axial-leaded TVS mounted directly at adapter output connector to suppress plug-in/out spikes and ESD. Use Value: E3 suffix ensures lead-free assembly compatibility; 1.5KE package allows manual rework and automated insertion in high-volume consumer manufacturing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE15A-E3/54 | Identical electrical specs and package; same Vishay part number family, differing only in part numbering convention (1N6275A vs. 1.5KE15A) | No functional difference; both rated for 15 V nominal clamping, same thermal and surge ratings | Select based on BOM legacy or distributor stock preference - electrically and mechanically interchangeable |
| SMBJ15A-E3/52 | Surface-mount SMB package (vs. axial 1.5KE), lower 600 W PPPM, identical VBR/VC specs | Suitable for space-constrained PCBs but requires layout redesign; not drop-in for through-hole designs | Choose SMBJ15A-E3/52 only when board real estate is limited and 600 W surge margin suffices |
Compared with 1N6275-E3/54, 1.5KE15A-E3/54 offers identical protection performance in the same axial package, while SMBJ15A-E3/52 trades mechanical fit and peak power for SMT compatibility - making the former a seamless replacement and the latter a layout-dependent alternative.

FAQ
What is the breakdown voltage tolerance of the 1N6275-E3/54?
The 1N6275-E3/54 has a specified breakdown voltage range of 14.3 V to 15.8 V at 1.0 mA test current, yielding ±5.3% tolerance around the nominal 15 V rating. This tight VBR window ensures predictable clamping onset and compatibility with 12 V systems where headroom above VWM = 12.8 V must be maintained without premature conduction.
Is the 1N6275-E3/54 suitable for bidirectional transient protection?
No, the 1N6275-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the 1N6275CA variant (or 1.5KE15CA), which suppresses transients in both polarities and lacks polarity marking. Using 1N6275-E3/54 in AC or floating-line applications risks failure due to forward conduction during negative excursions.
What is the maximum clamping voltage of the 1N6275-E3/54 under surge conditions?
The 1N6275-E3/54 clamps to a maximum of 21.2 V when subjected to its rated peak pulse current of 70.8 A (10/1000 µs waveform). This VC value is guaranteed per datasheet and represents the highest voltage imposed on the protected circuit during worst-case transient events - critical for ensuring downstream 24 V-tolerant ICs remain within absolute maximum ratings.
Does the 1N6275-E3/54 meet automotive qualification standards?
The base 1N6275-E3/54 is commercial grade and not AEC-Q101 qualified. However, Vishay offers the 1N6275AHE3_B variant (with HE3 suffix and revision code), which is AEC-Q101 qualified for automotive use. Engineers requiring automotive-grade assurance must specify the HE3 version - the E3/54 variant alone does not carry that qualification.
How does the 1N6275-E3/54 compare to standard Zener diodes in surge protection?
Unlike general-purpose Zener diodes, the 1N6275-E3/54 is optimized for transient suppression: it delivers 1500 W peak pulse power (vs. typically <10 W for Zeners), sub-nanosecond response, and controlled clamping with low dynamic impedance. Standard Zeners cannot sustain the energy or current of lightning or EFT events - the 1N6275-E3/54's ruggedized junction and packaging make it purpose-built for such demands.
