Product details
Overview
1N6296AHE3_A/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V), 1500 W peak pulse power (10/1000 µs), 152 V maximum clamping voltage at 9.9 A, 94.0 V stand-off voltage (VWM), and operates across –55 °C to +175 °C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6296AHE3_A/C datasheet, 1N6296AHE3_A/C pinout, 1N6296AHE3_A/C application, or 1N6296AHE3_A/C equivalent, this part delivers verified AEC-Q101 qualification, glass-passivated junction reliability, low incremental surge resistance, and UL 94 V-0 molded epoxy packaging - critical for high-reliability transient suppression in automotive ECUs and industrial PLC I/O modules.
Technical Context
This unidirectional TVS diode uses a silicon planar junction structure with glass passivation to achieve fast response (<1 ns), stable breakdown characteristics, and robust surge handling. Its 1500 W peak pulse rating is defined per 10/1000 µs waveform at 0.01% duty cycle, with thermal resistance of RθJA = 75 °C/W and RθJL = 15.4 °C/W enabling effective lead-mounted heat dissipation.
The device exhibits a 0.107 %/°C temperature coefficient of VBR, ensuring predictable voltage drift over temperature, and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Its 3.5 V forward voltage at 100 A (per spec note) confirms low conduction loss during fault events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | DO-214AA package (SMB), 110 V VBR, 600 W PPPM, lower surge capacity | Surface-mount layout; suited for space-constrained PCBs but lower power handling | Select when board area is limited and peak surge energy is ≤600 W |

FAQ
What is the breakdown voltage tolerance for 1N6296AHE3_A/C?
The 1N6296AHE3_A/C has a specified breakdown voltage (VBR) range of 105 V to 116 V at 1 mA test current, representing a ±5% tolerance around the nominal 110 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable system-level overvoltage margining in automotive and industrial designs.
Is 1N6296AHE3_A/C suitable for bidirectional transient suppression?
No, 1N6296AHE3_A/C is a unidirectional TVS diode - its cathode is marked with a band and it conducts only when the anode is negative relative to the cathode. For bidirectional protection, Vishay offers the 1N6296CA variant (not 1N6296AHE3_A/C), which lacks polarity marking and clamps in both directions.
What does the "HE3_A/C" suffix mean in 1N6296AHE3_A/C?
The "HE3" suffix indicates RoHS-compliant construction with JESD 201 Class 2 whisker resistance; "A/C" denotes the revision code per Vishay's internal documentation. This suffix confirms AEC-Q101 qualification, matte tin-plated leads, and UL 94 V-0 flammability rating - all verified in the 88301 datasheet.
Can 1N6296AHE3_A/C replace 1.5KE110A in existing designs?
Yes - 1N6296AHE3_A/C and 1.5KE110A are functionally identical parts with matching electrical specifications, package (DO-201AD), pinout, and qualification. The 1N6296AHE3_A/C is the commercial-grade, AEC-Q101-qualified version of the same 1.5KE110A base device, making it a direct drop-in replacement.
What is the maximum clamping voltage of 1N6296AHE3_A/C at rated peak pulse current?
The 1N6296AHE3_A/C has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 9.9 A, measured using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for validating downstream component voltage ratings.
