Product details
Overview
P6KE20HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 20 V breakdown voltage (VBR = 19.0–21.0 V at 1.0 mA), 17.1 V stand-off voltage (VWM), clamps to ≤27.7 V at 21.7 A peak pulse current (10/1000 μs), and delivers 600 W peak pulse power - used in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE20HE3/54 datasheet, P6KE20HE3/54 pinout, P6KE20HE3/54 application, or P6KE20HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.090 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamping device with a glass-passivated PN junction, optimized for fast response (<1 ns) to transient surges induced by inductive switching or ESD events. Its uni-directional polarity uses a cathode band marking and exhibits 3.5 V maximum forward voltage at 50 A, enabling integration into DC-biased protection paths without forward conduction interference.
The device is rated for 100 A non-repetitive surge current (8.3 ms half-sine), derates linearly above 25 °C ambient per Fig. 2, and maintains stable clamping performance across -55 °C to +175 °C operating range. Thermal resistance is 20 °C/W junction-to-lead, supporting reliable power dissipation under repetitive transients when mounted on adequate copper area.
Key Specifications

Use Value: Provides 600 W surge handling without degrading signal rise/fall times due to minimal parasitic capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | Same VBR (19.0–21.0 V), but SMA package (surface-mount); lower IPPM (21.2 A vs. 21.7 A); 400 W PPPM | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs or high-vibration environments | Select when board space is constrained and automated assembly is preferred over axial-leaded reliability |
| P6KE20A-E3/54 | Identical electrical specs and DO-15 package, but commercial-grade (non-AEC-Q101); same HE3 RoHS marking | Lacks automotive qualification testing - not approved for under-hood or safety-critical ECUs | Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with SMAJ20A and P6KE20A-E3/54, the P6KE20HE3/54 uniquely combines AEC-Q101 qualification, 600 W surge capability, and axial-leaded mechanical robustness - making it the only option qualified for automotive power rail protection without layout change or derating.

FAQ
What is the clamping voltage of P6KE20HE3/54 at its rated peak pulse current?
The P6KE20HE3/54 clamps to a maximum of 27.7 V when subjected to its rated 21.7 A peak pulse current (10/1000 μs waveform). This value is measured under standardized test conditions per JEDEC and guarantees that downstream circuitry will not experience voltages exceeding this level during specified surge events. The clamping voltage directly determines the protection margin for sensitive ICs connected to the same rail as the P6KE20HE3/54.
Is P6KE20HE3/54 suitable for automotive applications?
Yes, the P6KE20HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction - glass-passivated junction, DO-15 package with matte tin leads, and operation up to +175 °C - meets the environmental and reliability requirements defined in the AEC-Q101 standard. This makes P6KE20HE3/54 appropriate for under-hood and chassis-mounted applications where thermal and vibration stresses are present.
How does the HE3 suffix differ from E3 in P6KE20HE3/54?
The HE3 suffix in P6KE20HE3/54 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker resistance only. Both meet RoHS requirements, but only HE3 devices undergo full automotive stress testing (e.g., temperature cycling, HTRB, and ESD). Therefore, P6KE20HE3/54 is the correct choice when automotive qualification is mandatory, while P6KE20A-E3/54 serves commercial applications where such validation is unnecessary.
What is the maximum reverse leakage current for P6KE20HE3/54 at its working voltage?
The maximum reverse leakage current (ID) for P6KE20HE3/54 is 1.0 μA at its stand-off voltage (VWM) of 17.1 V and ambient temperature of 25 °C. This low leakage ensures minimal power drain in always-on systems such as automotive body control modules or battery-backed IoT sensors. Leakage remains within specification across the full -55 °C to +125 °C operating range, supporting reliable performance in wide-temperature deployments of P6KE20HE3/54.
Can P6KE20HE3/54 be used in bi-directional protection circuits?
No, P6KE20HE3/54 is a uni-directional TVS diode, indicated by the absence of "CA" suffix and presence of cathode band marking. Bi-directional variants (e.g., P6KE20CA) are required for AC line or differential signal protection where voltage transients can occur in either polarity. Using P6KE20HE3/54 in bi-directional applications would leave the anode-to-cathode reverse path unprotected, risking failure during negative-going surges. Always verify polarity designation before selecting P6KE20HE3/54 for a given circuit topology.
