Product details
Overview
P6KE13CHE3/73 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 13 V breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE13CHE3/73 datasheet, P6KE13CHE3/73 pinout, P6KE13CHE3/73 application, or P6KE13CHE3/73 equivalent, this AEC-Q101-qualified DO-15 device delivers validated surge immunity for 12 V automotive systems, meets UL 497B recognition (QVGQ2), and supports design verification of clamping margin against ISO 7637-2 Pulse 1/2a/5a transients.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA leakage at 11.1 V; when transient voltage exceeds VBR, it avalanches rapidly (<1 ns response) to clamp the line at ≤18.2 V while diverting up to 33.0 A. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.081 %/°C).
Thermally, it sustains 175 °C max junction temperature with RθJL = 20 °C/W and RθJA = 75 °C/W; its 100 A IFSM (8.3 ms half-sine) enables robust handling of repetitive load-dump events. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
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 reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| VC @ IPPM | 18.2 V at 33.0 A (10/1000 µs) - clamping voltage limiting downstream IC stress during surge events |
| PPPM | 600 W - peak transient energy absorption capacity without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current handling for automotive load-dump and inductive switching |

Use Value: 175 °C TJ max allows placement near hot transformers; DO-15 package fits tight spacing constraints in compact adapters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA package; 13.3–14.7 V VBR; 200 W PPPM; unidirectional; RoHS-compliant but not AEC-Q101 qualified | Limited to commercial/industrial use; lower surge rating requires parallel staging for automotive load-dump | Select when board space permits SMC footprint and AEC-Q101 is not required |
| 1.5KE13A | DO-201AD package; identical VBR (12.4–13.7 V) and PPPM (600 W); same AEC-Q101 qualification (HE3 variant available); higher thermal resistance (RθJA = 100 °C/W) | Same functional protection level but larger footprint and reduced thermal performance in confined layouts | Choose only if legacy DO-201AD footprint compatibility is mandatory |
Compared with SMBJ13A and 1.5KE13A, P6KE13CHE3/73 offers optimal balance of AEC-Q101 validation, DO-15 compactness, and 600 W surge capability - making it the preferred choice for new automotive and space-constrained industrial designs requiring certified reliability.

FAQ
What is the breakdown voltage tolerance of P6KE13CHE3/73?
The P6KE13CHE3/73 has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, corresponding to ±5% tolerance around the nominal 13 V rating. This tight VBR spread ensures consistent clamping behavior across production lots and supports robust design margining in 12 V automotive systems where P6KE13CHE3/73 is commonly deployed.
Is P6KE13CHE3/73 suitable for bi-directional transient protection?
No, P6KE13CHE3/73 is a uni-directional TVS diode - its cathode band indicates polarity, and it conducts only in reverse avalanche mode. For bi-directional protection, Vishay offers the P6KE13CHE3/73's counterpart P6KE13CHE3/73CA (with CA suffix), which provides symmetrical clamping for AC-coupled or floating signal lines. Using P6KE13CHE3/73 in bi-directional applications risks forward conduction damage.
What does the 'HE3' suffix signify in P6KE13CHE3/73?
The 'HE3' suffix in P6KE13CHE3/73 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike standard 'E3' parts, HE3 devices undergo accelerated stress testing for automotive reliability, including high-temperature operating life, temperature cycling, and biased humidity testing - confirming P6KE13CHE3/73's suitability for under-hood and safety-critical vehicle subsystems.
How does P6KE13CHE3/73 compare to SMAJ13A in surge handling?
P6KE13CHE3/73 delivers 600 W peak pulse power (10/1000 µs), whereas SMAJ13A is rated at 400 W. This 50% higher surge capacity allows P6KE13CHE3/73 to withstand harsher transients like ISO 7637-2 Pulse 5a without degradation. Additionally, P6KE13CHE3/73's DO-15 package offers lower RθJL (20 °C/W vs. SMAJ's ~35 °C/W), improving thermal survivability during repetitive surges - a key advantage in automotive gate driver protection where P6KE13CHE3/73 is frequently specified.
Can P6KE13CHE3/73 be used in place of P6KE13A?
Yes - P6KE13CHE3/73 is the AEC-Q101-qualified, RoHS-compliant, and whisker-resistant version of P6KE13A. Electrically identical (same VBR, VWM, VC, PPPM), it adds automotive-grade reliability and enhanced plating integrity. Designers upgrading legacy P6KE13A designs to meet modern automotive qualification requirements should directly substitute P6KE13CHE3/73 without circuit or layout changes, as both share the DO-15 package and pinout.
