Product details
Overview
1N6276AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 15.2 V to 16.8 V breakdown voltage range at 1.0 mA test current, 13.6 V maximum standoff voltage, 22.5 V clamping voltage at 66.7 A peak pulse current, and 1500 W peak pulse power capability with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6276AHE3_B/C datasheet, 1N6276AHE3_B/C pinout, 1N6276AHE3_B/C application, or 1N6276AHE3_B/C equivalent, this part delivers verified AEC-Q101 qualification (per note 2), RoHS-compliant matte tin-plated leads, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molded epoxy packaging - critical for automotive, industrial, and telecom surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, activating when transient voltage exceeds its 13.6 V standoff threshold and clamping to ≤22.5 V at 66.7 A. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, supporting robust protection of sensitive downstream components without affecting normal circuit operation.
The device is rated for -55 °C to +175 °C operating junction temperature, with thermal resistance of 15.4 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient). It sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 0.086 %/°C temperature coefficient of breakdown voltage - enabling stable performance across wide thermal environments.

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-E3/52 | DO-214AA package (SMB), 15 V VBR, 24.4 V VC at 61.5 A, 600 W rating | Lower power handling; surface-mount only; suited for space-constrained PCBs | Select when board area is limited and 600 W surge immunity suffices |
| 1.5KE16AHE3_B/C | Same family, identical electrical specs and AEC-Q101 qualification; alternate manufacturer marking | No functional or application difference - direct cross-reference per Vishay documentation | Use interchangeably where procurement or inventory policy favors 1.5KE prefix |
Compared with SMBJ15A-E3/52, the 1N6276AHE3_B/C offers 2.5× higher peak pulse power (1500 W vs. 600 W) and through-hole mechanical robustness; compared with 1.5KE16AHE3_B/C, it is electrically identical but designated under the legacy 1N62xxA numbering convention - both share DO-201AD package, AEC-Q101 qualification, and UL 94 V-0 compliance.

FAQ
What is the breakdown voltage tolerance for 1N6276AHE3_B/C?
The 1N6276AHE3_B/C has a specified breakdown voltage range of 15.2 V to 16.8 V at 1.0 mA test current, representing ±5.3% tolerance around the nominal 16 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level overvoltage margining in designs using the 1N6276AHE3_B/C.
Is 1N6276AHE3_B/C suitable for automotive applications?
Yes, the 1N6276AHE3_B/C is explicitly AEC-Q101 qualified per Vishay documentation (note 2, page 3), covering stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. Its -55 °C to +175 °C operating range and DO-201AD mechanical robustness make it appropriate for engine control units, body electronics, and infotainment power supplies where the 1N6276AHE3_B/C is deployed.
What is the clamping voltage of 1N6276AHE3_B/C at rated peak pulse current?
The 1N6276AHE3_B/C clamps to a maximum of 22.5 V when subjected to its rated peak pulse current of 66.7 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - a key parameter for validating safe operation of downstream ICs with the 1N6276AHE3_B/C in place.
Does 1N6276AHE3_B/C have a bidirectional variant?
No, the 1N6276AHE3_B/C is strictly unidirectional. Bidirectional variants in the same family use the "CA" suffix (e.g., 1N6276CA), but Vishay's datasheet lists only unidirectional types from 1N6267A through 1N6303A. The 1N6276AHE3_B/C's polarity is marked by a cathode band and must be oriented correctly in-circuit to function - it does not support AC or dual-rail clamping.
What package type does 1N6276AHE3_B/C use, and what are its mounting considerations?
The 1N6276AHE3_B/C uses the DO-201AD package (Case Style 1.5KE), a through-hole axial-leaded outline with 0.375" (9.5 mm) lead length. Mounting requires standard wave or hand soldering at ≤275 °C for 10 s max; leads are matte tin-plated and compliant with J-STD-002 and JESD 22-B102. Board layout must observe minimum creepage/clearance distances per IEC 61000-4-5 for the 1N6276AHE3_B/C's 22.5 V clamping level.
