Product details
Overview
1.5KE130AHE3/51 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 124 V to 137 V breakdown voltage (VBR) at 1 mA, 111 V maximum stand-off voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used in automotive power line and industrial sensor interface protection.
For engineers reviewing the 1.5KE130AHE3/51 datasheet, 1.5KE130AHE3/51 pinout, 1.5KE130AHE3/51 application, or 1.5KE130AHE3/51 equivalent, this part delivers AEC-Q101 qualification, glass passivated junction, 175 °C max junction temperature, RoHS-compliant matte tin plating, and JESD 201 Class 2 whisker resistance - critical for high-reliability automotive and industrial designs requiring robust surge immunity.
Technical Context
This uni-directional TVS diode operates as a voltage-clamped shunt protector, activating when transient voltage exceeds its VWM (111 V) and clamping to ≤179 V at 8.4 A (10/1000 µs). Its response time is <1 ns, enabling protection of fast-switching MOSFETs and microcontrollers against ESD and inductive switching spikes.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation up to 175 °C junction temperature. The device is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) and dissipates 6.5 W on infinite heatsink at TL = 75 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | DO-214AA package (SMB), 130 V VBR, 1000 W PPPM, lower IPPM (6.5 A) | Lower power handling; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ130A when board area is limited and surge energy is ≤1000 W; verify thermal derating for ambient >85 °C |
| 1.5KE130CA | Bi-directional variant, same VBR/VC, identical 1500 W rating, no polarity marking | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN bus) | Choose 1.5KE130CA only if protecting symmetrical waveforms; 1.5KE130AHE3/51 remains optimal for DC power rails with defined polarity |
Compared with SMBJ130A and 1.5KE130CA, the 1.5KE130AHE3/51 offers superior 1500 W surge capacity in an axial package ideal for through-hole mounting and high-current thermal paths, while maintaining AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - making it the preferred choice for automotive and industrial power-line protection where reliability and energy handling are paramount.

FAQ
What is the breakdown voltage range of the 1.5KE130AHE3/51?
The 1.5KE130AHE3/51 has a guaranteed breakdown voltage (VBR) range of 124 V to 137 V at a test current of 1 mA, measured per JEDEC standard. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 100–120 V DC systems. The 1.5KE130AHE3/51 maintains this specification under TA = 25 °C and conforms to the full 1.5KE family's ±5 % VBR limit.
Is the 1.5KE130AHE3/51 qualified for automotive use?
Yes, the 1.5KE130AHE3/51 carries the HE3 suffix, indicating AEC-Q101 qualification per Vishay's documentation. It has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive applications. The 1.5KE130AHE3/51 is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the 1.5KE6.8AHE3_A to 1.5KE220AHE3_A group.
What is the clamping voltage of the 1.5KE130AHE3/51 at its rated peak pulse current?
The 1.5KE130AHE3/51 clamps to a maximum of 179 V at its rated peak pulse current (IPPM) of 8.4 A, tested with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream components during surge events and is critical for ensuring compatibility with 200 V-rated MOSFETs and ICs. The 1.5KE130AHE3/51 achieves this clamping performance while maintaining low incremental surge resistance for minimal voltage overshoot.
Does the 1.5KE130AHE3/51 have RoHS and lead-free compliance?
Yes, the HE3 suffix on 1.5KE130AHE3/51 denotes full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. The device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, and its molding compound meets UL 94 V-0 flammability rating. The 1.5KE130AHE3/51 also satisfies JESD 201 Class 2 whisker resistance requirements for long-term reliability.
How does the thermal performance of the 1.5KE130AHE3/51 compare to surface-mount alternatives?
The 1.5KE130AHE3/51 offers RθJL = 15.4 °C/W (junction-to-lead), significantly lower than typical SMD TVS devices (e.g., SMBJ series: ~30–40 °C/W), due to its axial DO-201AD package and direct lead heat path. This enables higher sustained power dissipation - 6.5 W on infinite heatsink at TL = 75 °C - and better thermal stability in high-ambient environments. The 1.5KE130AHE3/51 is especially advantageous where forced airflow or heatsinking is impractical.
