Product details
Overview
1N6299AHE3/51 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 143 V minimum breakdown voltage (VBR), 128 V maximum stand-off voltage (VWM), and clamps transients to ≤207 V at 7.2 A peak pulse current - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the 1N6299AHE3/51 datasheet, 1N6299AHE3/51 pinout, 1N6299AHE3/51 application, or 1N6299AHE3/51 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.106 %/°C VBR temperature coefficient, and compatibility with high-reliability automotive ECU and motor control board designs requiring robust lightning and load-dump immunity.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast clamping response (<1 ns) and low incremental surge resistance. Its uni-directional polarity enables integration into polarized DC circuits where reverse-bias blocking is required alongside transient suppression.
The device operates within -55 °C to +175 °C junction temperature range and delivers stable clamping performance under repetitive 10/1000 µs surges at 0.01 % duty cycle. Thermal resistance from junction to lead is 15.4 °C/W, supporting direct PCB trace heat sinking without external heatsinks in moderate-power applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), 150 V VBR min | Preferred for space-constrained PCBs; less suited for high-energy automotive load dump events | Select when footprint reduction outweighs peak power requirement and thermal mass needs are lower |
| 1.5KE150A | Same electrical specs and DO-201AD package; differs only in packaging suffix (E3 vs. HE3) and AEC-Q101 qualification status | Commercial-grade alternative lacking automotive qualification documentation and whisker test compliance | Use only in non-automotive industrial applications where AEC-Q101 and JESD 201 Class 2 are not mandated |
Compared with SMBJ150A, 1N6299AHE3/51 delivers 2.5× higher surge power handling and superior thermal robustness via larger case; compared with 1.5KE150A, it adds AEC-Q101 qualification and enhanced whisker resistance - critical for automotive production programs requiring full PPAP compliance.

FAQ
What is the breakdown voltage tolerance of the 1N6299AHE3/51?
The 1N6299AHE3/51 has a specified breakdown voltage range of 143 V (min) to 158 V (max) at 1.0 mA test current, yielding a ±5.3 % tolerance. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 125 V nominal systems where the 1N6299AHE3/51 is commonly applied.
Is the 1N6299AHE3/51 RoHS and REACH compliant?
Yes, the 1N6299AHE3/51 carries the HE3 suffix, indicating full RoHS compliance per Directive 2011/65/EU and adherence to Vishay's material declaration standard (doc. 99912). It also meets JESD 201 Class 2 whisker resistance requirements and UL 94 V-0 flammability rating - verified in the official Vishay document 88301.
Does the 1N6299AHE3/51 have AEC-Q101 qualification?
Yes, the 1N6299AHE3/51 is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88301, Section "RATINGS AND CHARACTERISTICS CURVES", Note (1). This qualification covers temperature cycling, high-temperature operating life, and mechanical shock testing - making the 1N6299AHE3/51 suitable for automotive powertrain and chassis applications.
What is the maximum clamping voltage of the 1N6299AHE3/51 at rated peak pulse current?
The 1N6299AHE3/51 clamps to a maximum of 207 V at its rated peak pulse current of 7.2 A (10/1000 µs waveform), per Table "ELECTRICAL CHARACTERISTICS" in Vishay document 88301. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Can the 1N6299AHE3/51 be used in bi-directional configurations?
No, the 1N6299AHE3/51 is a uni-directional TVS diode, indicated by the "A" suffix (not "CA"). Its electrical characteristics - including VBR, VWM, and clamping behavior - apply only in forward conduction mode (anode negative relative to cathode). For bi-directional protection, Vishay specifies parts such as 1N6299CAHE3/51, which is not interchangeable with the 1N6299AHE3/51.
