Product details
Overview
1.5KE13HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 13 V nominal breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 11.1 V maximum stand-off voltage (VWM), and clamps transients to ≤18.2 V at 82.4 A peak pulse current (10/1000 µs), delivering 1500 W peak pulse power. It is RoHS-compliant, AEC-Q101 qualified (HE3 suffix), and used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching spikes.
For engineers reviewing the 1.5KE13HE3/54 datasheet, 1.5KE13HE3/54 pinout, 1.5KE13HE3/54 application, or 1.5KE13HE3/54 equivalent, this page provides verified electrical parameters, thermal derating behavior, clamping performance under standardized surge waveforms, JEDEC 1.5KE package mechanical data, and validated alternatives for automotive, industrial, and telecom surge protection designs.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches rapidly (<1 ns response) to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (≤5.0 µA at VWM), while its 15.4 °C/W junction-to-lead thermal resistance supports reliable power dissipation during repetitive transients.
The device complies with JEDEC standard 1.5KE case outline and is rated for -55 °C to +175 °C operating junction temperature. It sustains 200 A non-repetitive forward surge (8.3 ms half-sine) and exhibits a positive temperature coefficient of VBR (+0.081 %/°C), enabling predictable voltage margining across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation threshold for accurate overvoltage trip point |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage rises significantly |
| VC @ IPPM | ≤18.2 V at 82.4 A (10/1000 µs) - clamping voltage determines protected circuit's maximum transient stress level |
| PPPM | 1500 W - peak pulse power handling capacity for standardized lightning/surge immunity testing |
| IFSM | 200 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during fault conditions |
| TJ max | +175 °C - enables operation in high-temperature environments such as engine compartments or enclosed industrial enclosures |
| RθJL | 15.4 °C/W - low thermal resistance from junction to lead allows effective heat transfer to PCB copper or heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA (SMB) package; 13 V VBR; 600 W PPPM; higher capacitance (~1000 pF) | Lower peak power rating limits use in high-energy surge environments like automotive load dump | Select when board space is constrained and surge energy is ≤600 W (e.g., USB port protection) |
| 1.5KE13A-E3/54 | Same 1.5KE package and VBR/VC specs, but commercial-grade (non-AEC-Q101); identical pinout and footprint | Lacks automotive qualification; unsuitable for under-hood or safety-critical vehicle systems | Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with 1.5KE13HE3/54, SMBJ13A offers smaller footprint but reduced surge robustness, while 1.5KE13A-E3/54 matches form-fit-function but lacks automotive reliability validation-making 1.5KE13HE3/54 the only AEC-Q101-qualified 1500 W option in the 13 V class with JEDEC 1.5KE packaging.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13HE3/54?
The 1.5KE13HE3/54 has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing ±5.4% tolerance around the nominal 13 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margining in safety-critical designs.
Is the 1.5KE13HE3/54 suitable for bidirectional transient protection?
No, the 1.5KE13HE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It protects only against reverse-polarity transients on the cathode side. For bidirectional protection at ~13 V, the 1.5KE13CA variant must be used-though that part is limited to VBR ≤220 V and is not AEC-Q101 qualified in HE3 format.
What does the "HE3/54" suffix mean in 1.5KE13HE3/54?
In 1.5KE13HE3/54, "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13" paper tape and reel with 1400 units per reel. The base part number remains 1.5KE13A, with HE3 confirming automotive-grade reliability and 54 indicating the preferred delivery format.
How does the 1.5KE13HE3/54 perform under elevated ambient temperatures?
The 1.5KE13HE3/54 derates linearly above 25 °C ambient: its peak pulse power drops to ~1125 W at 75 °C and ~750 W at 125 °C (per Fig. 2). Its +0.081 %/°C VBR temperature coefficient ensures predictable voltage margining, and its 175 °C max junction temperature supports operation in under-hood automotive locations.
Can the 1.5KE13HE3/54 replace the older 1N6274A in existing designs?
Yes, the 1.5KE13HE3/54 is the direct successor to 1N6274A, sharing identical electrical specifications (VBR, VWM, VC, PPPM), JEDEC 1.5KE package, and pinout. The HE3 version adds AEC-Q101 qualification, RoHS compliance, and enhanced whisker resistance-making it a drop-in upgrade for automotive and high-reliability applications previously using 1N6274A.
