Product details
Overview
1N6272AHE3_B/C 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 10.5–11.6 V breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V clamping voltage at 96.2 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD in industrial power supplies.
For engineers reviewing the 1N6272AHE3_B/C datasheet, 1N6272AHE3_B/C pinout, 1N6272AHE3_B/C application, or 1N6272AHE3_B/C equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), and real-world clamping behavior under standardized surge waveforms.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its clamping action begins at 10.5 V (min VBR) and limits transient voltage to ≤15.6 V at 96.2 A (10/1000 µs), enabling robust protection of 12 V nominal systems without compromising normal operation.
It supports repetitive surge events at ≤0.01% duty cycle and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine). The device meets JESD 201 Class 2 whisker resistance (HE3 suffix) and UL 94 V-0 flammability requirements via its molded epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - Ensures reliable conduction onset above 12 V rail noise while avoiding false triggering. |
| VWM | 9.40 V - Maximum continuous reverse voltage before leakage exceeds 5.0 µA; compatible with 9 V–12 V system margins. |
| VC @ IPPM | 15.6 V - Clamped voltage during 96.2 A transient; protects downstream 16 V-rated components. |
| PPPM | 1500 W - Peak power handling per 10/1000 µs waveform; sufficient for IEC 61000-4-5 Level 4 surges. |
| IPPM | 96.2 A - Peak pulse current capability; enables single-device protection for moderate-energy transients. |
| TJ max. | +175 °C - High-temperature operation supports under-hood automotive and industrial motor drive environments. |
| RθJL | 15.4 °C/W - Low junction-to-lead thermal resistance allows effective heat dissipation through PCB copper pours or heatsinked leads. |
Pinout & Package
Package: JEDEC-standard Case Style 1.5KE - axial-leaded, molded epoxy body (UL 94 V-0), 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 conduction terminal | Connected to system ground or lower-potential node; conducts during positive transients when cathode is at higher potential. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line (e.g., 12 V rail); initiates clamping when voltage exceeds VBR in reverse direction. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE11AHE3_B/C | Identical electrical specs and package; same VBR, VWM, VC, and PPPM; direct cross-reference per Vishay documentation. | No functional difference; both rated for 12 V system protection with identical thermal and surge performance. | Select 1.5KE11AHE3_B/C if sourcing from alternate part numbering conventions; electrically and mechanically interchangeable. |
| SMBJ11A-E3/52 | Surface-mount SMB package (vs. axial 1.5KE), lower PPPM (600 W), higher VC (18.2 V @ 32.9 A), RθJA = 110 °C/W. | Suitable only for lower-energy transients; requires PCB layout change and thermal relief design due to SMT footprint and reduced power rating. | Choose SMBJ11A-E3/52 only for space-constrained designs where 600 W protection suffices and reflow compatibility is required. |
Compared with 1N6272AHE3_B/C, 1.5KE11AHE3_B/C offers identical protection performance in the same axial package, while SMBJ11A-E3/52 trades peak power and thermal robustness for board-space savings-making it unsuitable for high-energy industrial or automotive surge scenarios.

FAQ
What is the breakdown voltage range of the 1N6272AHE3_B/C?
The 1N6272AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 10.5 V to 11.6 V at 1.0 mA test current. This tight tolerance ensures consistent clamping onset across production lots and supports precise coordination with downstream overvoltage thresholds in 12 V systems. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is the 1N6272AHE3_B/C AEC-Q101 qualified?
Yes, the 1N6272AHE3_B/C is AEC-Q101 qualified as indicated by the "HE3_B" suffix and confirmed in Note (2) on page 3 of the Vishay document 88301. This qualification covers stress testing for temperature cycling, humidity bias, and mechanical shock-validating suitability for automotive powertrain and body electronics applications where reliability is mission-critical.
What is the clamping voltage of the 1N6272AHE3_B/C at its rated peak pulse current?
The 1N6272AHE3_B/C clamps to a maximum of 15.6 V at its rated peak pulse current (IPPM) of 96.2 A under the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay 88301 datasheet and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
Can the 1N6272AHE3_B/C be used in bidirectional configurations?
No, the 1N6272AHE3_B/C is a unidirectional TVS diode, as confirmed by its part number structure (no "C" suffix) and the polarity note on page 1 stating "for unidirectional types the color band denotes cathode end." Bidirectional variants in this family carry the "CA" suffix (e.g., 1.5KE11CA), which the 1N6272AHE3_B/C does not include.
What is the thermal resistance from junction to lead (RθJL) for the 1N6272AHE3_B/C?
The 1N6272AHE3_B/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as published in the Thermal Characteristics table on page 3 of the Vishay 88301 datasheet. This low value enables efficient heat transfer from the silicon die to the PCB copper or external heatsink via the axial leads, supporting sustained operation under repetitive surge conditions.
