Product details
Overview
1.5KE13CHE3/54 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 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 in automotive power supply input stages.
For engineers reviewing the 1.5KE13CHE3/54 datasheet, 1.5KE13CHE3/54 pinout, 1.5KE13CHE3/54 application, or 1.5KE13CHE3/54 equivalent, key selection criteria include verified clamping voltage under 10/1000 µs surge, unidirectional polarity with cathode band marking, JEDEC 1.5KE package thermal performance (RθJL = 15.4 °C/W), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression - response time is effectively instantaneous (≤1 ns). Its glass-passivated junction enables stable breakdown characteristics and low incremental surge resistance, critical for protecting downstream MOSFETs and ICs from inductive switching spikes and ESD events.
Rated for 175 °C maximum junction temperature and derated linearly above 25 °C ambient, it supports high-reliability operation in engine control units and industrial power supplies. The 1.5KE13CHE3/54 uses a molded epoxy case meeting UL 94 V-0 and matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset threshold for predictable clamping initiation |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | ≤18.2 V at 82.4 A (10/1000 µs) - ensures protected circuit sees no more than 18.2 V during worst-case surge |
| PPPM | 1500 W - peak transient energy handling capability per single 10/1000 µs pulse |
| IFSM | 200 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during fault conditions |
| TJ max. | +175 °C - enables deployment in under-hood automotive environments without thermal derating penalties |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports reliable power dissipation into PCB copper |

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 package (smaller footprint), lower PPPM = 600 W, VC = 21.5 V @ 28.5 A | Preferred for space-constrained PCBs where 600 W surge margin suffices | Select when board area is limited and full 1500 W rating is not required; verify thermal relief for SMB footprint |
| 1.5KE13A-E3/54 | Same 1.5KE package and electrical specs, but commercial-grade (non-AEC-Q101 qualified) | Suitable for non-automotive industrial or consumer applications with lower reliability requirements | Choose for cost-sensitive designs where AEC-Q101 qualification is unnecessary |
Compared with 1.5KE13CHE3/54, SMBJ13A trades surge capacity and thermal robustness for compactness, while 1.5KE13A-E3/54 retains identical protection performance but lacks automotive qualification - making the HE3 variant essential for Tier 1 automotive BOMs requiring traceable AEC compliance.

FAQ
What is the clamping voltage of the 1.5KE13CHE3/54 under a 10/1000 µs surge?
The 1.5KE13CHE3/54 clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 82.4 A (10/1000 µs waveform). This value is measured per JEDEC standard test conditions and reflects the actual voltage seen by protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The 1.5KE13CHE3/54 achieves this with a low clamping ratio of ~1.42 relative to its nominal breakdown voltage.
Is the 1.5KE13CHE3/54 suitable for automotive applications?
Yes, the 1.5KE13CHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), making it suitable for automotive applications including engine control units, body electronics, and infotainment power supplies. Its 175 °C maximum junction temperature, glass-passivated junction, and validated stress-test performance meet automotive reliability requirements. The 1.5KE13CHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the 1.5KE series.
How does the 1.5KE13CHE3/54 differ from the 1.5KE13A-E3/54?
The 1.5KE13CHE3/54 and 1.5KE13A-E3/54 share identical electrical specifications and 1.5KE package dimensions, but differ in qualification: the HE3 suffix indicates AEC-Q101 qualification, while the E3 suffix denotes commercial-grade only. The 1.5KE13CHE3/54 undergoes additional stress testing (e.g., HTGB, TCT, UHAST) required for automotive use. Both use RoHS-compliant matte tin plating and same thermal resistance (RθJL = 15.4 °C/W).
What is the standoff voltage (VWM) rating for the 1.5KE13CHE3/54?
The 1.5KE13CHE3/54 has a maximum working peak reverse voltage (VWM) of 11.1 V, meaning it can continuously block up to 11.1 V in reverse bias without exceeding 5.0 µA leakage current at 25 °C. This allows safe integration into 12 V automotive systems where nominal rail voltage may reach 13.5 V during charging - the 11.1 V VWM provides sufficient margin while enabling early avalanche onset for fast clamping. The 1.5KE13CHE3/54 datasheet confirms this value in Table 1 under "STAND-OFF VOLTAGE".
Does the 1.5KE13CHE3/54 have polarity marking, and how is it identified?
Yes, the 1.5KE13CHE3/54 is unidirectional and features a visible cathode band (color band) on the molded epoxy body, identifying the cathode terminal. Per Vishay documentation, this band denotes the high-side connection point - it must be connected to the line being protected (e.g., +12 V rail), while the anode connects to ground or low-impedance return. No marking is present on bidirectional variants, but the 1.5KE13CHE3/54 is explicitly unidirectional, confirmed by its part number suffix "A" and absence of "CA".
