Product details
Overview
P6KE11CHE3/54 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 10.5 V minimum breakdown voltage (VBR), 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE11CHE3/54 datasheet, P6KE11CHE3/54 pinout, P6KE11CHE3/54 application, or P6KE11CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 5.0 W power dissipation, and low 0.075 %/°C temperature coefficient of VBR, making it suitable for high-reliability automotive electronics where thermal stability and surge robustness are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 9.4 V), but triggers into low-impedance conduction when transient voltage exceeds VBR (10.5–11.6 V), limiting downstream voltage to ≤15.6 V at 38.5 A. Its glass-passivated junction ensures stable parametric performance across temperature and lifetime.
The device complies with AEC-Q101 stress testing for automotive use and supports soldering per J-STD-002/JESD 22-B102. With 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating, it delivers reliable thermal management on standard PCB land patterns without heatsinking for intermittent surge events.
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 |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), SMA package (surface-mount), VC = 16.0 V @ 25.6 A | Preferred for space-constrained PCBs; less robust for high-energy automotive load dumps | Select when board area is limited and surge energy is ≤400 W; verify thermal pad layout for 1.5 W steady-state dissipation |
| 1.5KE11A | Same DO-15 package, higher PPPM (1500 W), VC = 18.2 V @ 82.5 A, no AEC-Q101 qualification | Better for industrial AC mains protection; not validated for automotive temperature cycling or humidity testing | Choose for cost-sensitive industrial equipment where AEC-Q101 is not required and higher clamping voltage is acceptable |
Compared with SMAJ10A and 1.5KE11A, the P6KE11CHE3/54 uniquely balances AEC-Q101 qualification, 600 W surge capacity, and DO-15 through-hole manufacturability - making it optimal for automotive modules requiring proven reliability and legacy assembly compatibility.

FAQ
What is the clamping voltage of the P6KE11CHE3/54 under maximum surge conditions?
The P6KE11CHE3/54 has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and ensures downstream components experience no more than 15.6 V during transient events - critical for protecting 12 V logic and analog circuits. The P6KE11CHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE11CHE3/54 qualified for automotive applications?
Yes, the P6KE11CHE3/54 carries the HE3 suffix, indicating AEC-Q101 qualification per Vishay's documentation. It has passed stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress test (UHAST), and ESD per JESD22-A114. This makes the P6KE11CHE3/54 suitable for under-hood and cabin-mounted automotive modules where reliability under thermal and mechanical stress is mandatory.
What does the "HE3" suffix mean in P6KE11CHE3/54?
The "HE3" suffix in P6KE11CHE3/54 denotes two key attributes: RoHS compliance and AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 qualification, "E3" confirms RoHS compliance and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial-grade "E3" variant (e.g., P6KE11AE3/54), which lacks automotive qualification. The P6KE11CHE3/54 is therefore designated for mission-critical automotive use cases.
How does the P6KE11CHE3/54 compare to bi-directional TVS diodes like P6KE11CA?
The P6KE11CHE3/54 is uni-directional, meaning it protects against positive transients only (cathode to line, anode to ground), whereas P6KE11CA is bi-directional and handles both polarities. The P6KE11CHE3/54 offers tighter VBR tolerance (10.5–11.6 V vs. 10.5–12.1 V for P6KE11CA) and lower VC (15.6 V vs. 17.0 V). Use the P6KE11CHE3/54 where polarity is known and clamping precision matters - such as on regulated DC rails - and P6KE11CA where AC or bidirectional signals require protection.
What is the maximum continuous power dissipation for the P6KE11CHE3/54?
The P6KE11CHE3/54 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. In typical PCB applications without heatsinking, derating applies per Figure 5 in the datasheet: at 75 °C ambient, usable power drops to ~2.5 W. This rating governs long-term thermal design - the P6KE11CHE3/54 is intended for transient, not continuous, power dissipation.
