Product details
Overview
P6KE11H from Taiwan Semiconductor is an AEC-Q101 qualified unidirectional transient voltage suppressor (TVS) diode designed for automotive and industrial overvoltage protection. It features a 11 V nominal breakdown voltage (VBR min/max: 9.90–12.1 V), 8.92 V stand-off voltage (VWM), 16.2 V maximum clamping voltage at 38 A peak surge current, and 600 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the P6KE11H datasheet, P6KE11H pinout, P6KE11H application, or P6KE11H equivalent, key selection criteria include clamping performance under fast transients (response <1.0 ps), low leakage (<1 µA at 8.92 V), DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification for automotive ECU and sensor interface protection.
Technical Context
The P6KE11H operates as a unidirectional avalanche diode with sharp reverse-breakdown characteristics, optimized for clamping high-energy transients before they reach downstream ICs. Its junction temperature range spans −55 °C to +175 °C, and it maintains stable VBR with a temperature coefficient of 0.075 %/°C.
It delivers 600 W non-repetitive peak pulse power at 25 °C, derating linearly above that ambient; steady-state power dissipation is 5 W at 75 °C with specified lead mounting conditions. The device exhibits low dynamic impedance and fast response-typically less than 1.0 ps from 0 V to VBR-enabling effective suppression of ESD and electrical fast transients (EFT).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 9.90–12.1 V at IT = 1 mA - defines reliable avalanche onset window for consistent clamping threshold |
| VWM | 8.92 V - maximum continuous reverse voltage before significant leakage; ensures no false triggering in 9 V rail systems |
| VC @ IPP | 16.2 V at 38 A - clamping voltage during 10/1000 µs surge; limits stress on protected 12 V logic interfaces |
| PPK | 600 W - peak pulse power handling capability; supports ISO 7637-2 Pulse 1/2/5a immunity compliance |
| ID @ VWM | <1 µA - ultra-low reverse leakage preserves battery life in always-on automotive modules |
| TJ max | +175 °C - enables placement near hot components (e.g., power converters, engine control units) |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; completes clamping loop during transient events |
| Cathode | Protected line input | Connected to signal/power line being safeguarded (e.g., LIN bus, sensor supply); conducts avalanche current to ground when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood and body-control applications requiring extended temperature and lifetime reliability |
| 600 W surge rating (10/1000 µs) | Withstands severe load-dump and inductive switching surges common in 12 V vehicle electrical systems |

| UL 94V-0 flammability rating | Molding compound meets automotive safety standards for flame resistance in enclosed electronic assemblies |
Applications
| Automotive Sensor Interface Protection | LIN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting analog output sensors (e.g., pressure, temperature) connected to ECU inputs against battery load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VSUPPLY and ground to clamp positive-going transients before reaching ADC front-end. Use Value: Limits voltage excursion to ≤16.2 V, preventing latch-up or damage to 12 V-tolerant op-amps and SAR ADCs in engine bay modules. |
Use Scenario: Safeguarding LIN transceiver pins (e.g., TJA1020) from coupling noise and ESD during vehicle assembly and service. IC Role / Device Role / Timing Role: Standoff-connected TVS on LIN data line (dominant/recessive side) to absorb ±30 kV contact ESD per IEC 61000-4-2. Use Value: Sub-ns response ensures clamping occurs before LIN physical layer receiver input exceeds absolute maximum ratings (±18 V). |
| Industrial PLC Digital Input Protection | 12 V Power Rail Surge Guarding |
Use Scenario: Shielding optocoupler-based digital inputs in programmable logic controllers from field-wiring induced surges (IEC 61000-4-4/5). IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting transients away from series current-limiting resistor and opto-LED. Use Value: 600 W rating handles repetitive 2 kV ring wave surges without degradation; low VWM avoids false triggering during 12 V nominal operation. |
Use Scenario: Preventing overvoltage failure in 12 V DC power distribution networks feeding multiple embedded modules. IC Role / Device Role / Timing Role: Primary clamping device across input terminals of DC-DC converters or LDO regulators. Use Value: Clamps 10/1000 µs surges to ≤16.2 V, maintaining regulator enable thresholds and avoiding thermal shutdown cascades. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same 11 V nominal, but SMA package (SMT); lower PPK (400 W); VC = 18.2 V @ 22.5 A | Surface-mount layout; unsuitable for through-hole or high-power chassis-mounted designs | Select when board space is constrained and surge energy is ≤400 W; verify thermal pad design for sustained dissipation. |
| 1N6267A | Same DO-15 package and 11 V rating; PPK = 600 W; VC = 17.0 V @ 35.3 A; not AEC-Q101 qualified | General industrial use only; lacks automotive reliability validation and high-temp bias testing | Acceptable for cost-sensitive non-automotive applications where AEC-Q101 is not mandated. |
Compared with SMAJ11A and 1N6267A, the P6KE11H uniquely combines AEC-Q101 qualification, through-hole DO-15 mechanical robustness, and 16.2 V clamping at full 600 W rating-making it optimal for automotive power domain protection where regulatory compliance and thermal margin are critical.

FAQ
What is the clamping voltage of the P6KE11H under standard test conditions?
The P6KE11H has a maximum clamping voltage (VC) of 16.2 V when subjected to a 10/1000 µs surge current of 38 A. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during standardized transient events such as ISO 7637-2 Pulse 5a. The P6KE11H maintains this clamping performance across its full operating temperature range.
Is the P6KE11H suitable for bidirectional transient protection?
No, the P6KE11H is a unidirectional TVS diode intended for protection of DC lines referenced to ground. Its cathode-anode polarity is fixed, and it does not conduct in forward bias beyond ~1.2 V. For bidirectional protection (e.g., AC lines or differential buses), a P6KE11CA or similarly suffixed bipolar variant must be used instead of the P6KE11H.
Does the P6KE11H require a heatsink for continuous operation?
No heatsink is required for transient suppression duty cycles, as the P6KE11H is rated for non-repetitive pulses only. However, under sustained surge conditions exceeding one pulse per minute, thermal management becomes critical. At 75 °C ambient, its steady-state power dissipation is limited to 5 W with specified 5 × 5 mm copper pads-so PCB copper area serves as its primary thermal path, not an external heatsink.
How does the AEC-Q101 qualification of the P6KE11H impact its use in automotive designs?
The AEC-Q101 qualification of the P6KE11H confirms it has passed accelerated stress tests-including high-temperature reverse bias (HTRB), temperature cycling, and ESD-required for automotive under-hood and body electronics. This allows direct use in production ECUs without additional component-level qualification, reducing development time and ensuring long-term reliability in vehicles operating from −40 °C to +125 °C ambient.
What is the meaning of the 'H' suffix in P6KE11H?
The 'H' suffix in P6KE11H denotes AEC-Q101 qualification per the Taiwan Semiconductor ordering code convention. Unlike standard P6KE11 or P6KE11A variants, the P6KE11H undergoes additional screening and lot-level testing to meet automotive reliability requirements. It shares identical electrical specifications and DO-204AC packaging with non-H variants but carries certified test documentation for automotive program release.
