Product details
Overview
1N6296AHE3_B/C from Vishay General Semiconductor is a unidirectional 1500 W Transient Voltage Suppressor (TVS) diode with a breakdown voltage range of 105 V to 116 V at 1.0 mA test current, clamping voltage of 152 V at 9.9 A peak pulse current, and stand-off voltage of 94.0 V - designed for robust overvoltage protection on DC power rails and signal lines in industrial and automotive electronics.
For engineers reviewing the 1N6296AHE3_B/C datasheet, 1N6296AHE3_B/C pinout, 1N6296AHE3_B/C application, or 1N6296AHE3_B/C equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, RoHS-compliant HE3 suffix packaging, and thermal resistance (RθJL = 15.4 °C/W) for reliable transient energy dissipation in high-reliability PCB layouts.
Technical Context
This device operates as a unidirectional silicon avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01 % duty cycle, and it supports peak forward surge current up to 200 A (8.3 ms half-sine).
The 1N6296AHE3_B/C is rated for continuous operation from –55 °C to +175 °C junction temperature and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per note (2) in the Vishay document 88301.
Key Specifications

FAQ
What is the clamping voltage of the 1N6296AHE3_B/C under a 10/1000 µs surge?
The 1N6296AHE3_B/C clamps to a maximum of 152 V at 9.9 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and reflects the actual voltage seen by downstream components during surge events - critical for ensuring compatibility with 100 V-rated ICs and MOSFETs in the protected circuit.
Is the 1N6296AHE3_B/C qualified for automotive use?
Yes, the 1N6296AHE3_B/C carries the HE3 suffix, which denotes both RoHS compliance and AEC-Q101 qualification per Vishay document 88301 note (2). This certification covers the full 1.5KE6.8AHE3_B to 1.5KE220AHE3_B series and validates its suitability for automotive powertrain, body, and infotainment systems.
What does the "B/C" in 1N6296AHE3_B/C indicate?
The "B/C" suffix identifies the revision level and packaging configuration: "B" refers to the manufacturing revision code, and "C" specifies the preferred package code for 13-inch paper tape and reel delivery (1400 units per reel). This matches the ordering information shown in the Vishay 88301 datasheet.
How does the 1N6296AHE3_B/C differ from the standard 1N6296A?
The 1N6296AHE3_B/C adds RoHS compliance (E3), AEC-Q101 qualification (HE3), and JESD 201 Class 2 whisker resistance - whereas the base 1N6296A lacks these certifications and uses non-RoHS lead finish. All electrical parameters (VBR, VC, PPPM) remain identical between versions.
What is the thermal resistance from junction to lead (RθJL) for the 1N6296AHE3_B/C?
The 1N6296AHE3_B/C has a typical junction-to-lead thermal resistance of 15.4 °C/W, as specified in the Thermal Characteristics table of Vishay document 88301. This value guides PCB copper pour sizing and heatsinking decisions when managing repetitive surge duty cycles in high-temperature environments.
