Product details
Overview
P6KE10H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 10V nominal breakdown voltage (VBR min/max: 9.0–11.0V), 8.1V stand-off voltage (VWM), clamps to ≤15.0V at 10A peak surge current, and delivers sub-nanosecond response (<1.0ps) for ESD and EFT transients in automotive body electronics.
For engineers reviewing the P6KE10H datasheet, P6KE10H pinout, P6KE10H application, or P6KE10H equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-reliability PCB layouts, 175°C junction rating for under-hood use, and verified clamping performance under 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE10H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 9.0–11.0V breakdown range at 1mA test current. Its low dynamic impedance ensures stable clamping at 15.0V under 10A surge, limiting energy dissipation in protected ICs during 600W transient events.
Designed for automotive-grade reliability, it meets AEC-Q101 stress requirements including temperature cycling, humidity bias, and mechanical shock. The device's 0.073%/°C VBR temperature coefficient and <1μA leakage at 8.1V support stable operation across –55°C to +175°C ambient conditions without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.1 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12V automotive systems. |
| VBR (min/max) | 9.0 / 11.0 V at 1 mA - Confirmed avalanche onset range; ensures predictable triggering within specification tolerance. |
| VC @ IPP | 15.0 V at 10 A - Clamped voltage during full 600W 10/1000μs surge; limits downstream IC stress to safe levels. |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; supports IEC 61000-4-5 Level 4 immunity testing. |
| TJ max | +175 °C - Maximum junction temperature; enables placement near heat sources in engine control units. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400g mass; compatible with automated through-hole assembly. |
| Leakage ID | <1 μA at 8.1 V - Negligible standby current draw; preserves battery life in always-on vehicle modules. |

| Automotive Lighting Driver | Power Supply Input Stage |
Use Scenario: Overvoltage protection on LED driver IC supply rails subjected to alternator ripple and jump-start spikes. IC Role / Device Role / Timing Role: Placed upstream of buck controller IC to shunt 600W surges away from gate drivers and feedback networks. Use Value: 175°C junction rating allows direct mounting on heatsink-equipped lighting modules without derating. |
Use Scenario: Primary surge suppression on 24V industrial power supply input before rectification and filtering stages. IC Role / Device Role / Timing Role: First-line defense against lightning-induced surges (IEC 61000-4-5) entering via AC/DC adapter input terminals. Use Value: 600W rating handles 4kV/2kA combination wave surges without failure, reducing need for secondary MOV stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPK (400W), SMA package (surface-mount), 10.0–11.1V VBR range | Not AEC-Q101 qualified; suited for consumer-grade PCBs with space constraints | Select when board area is limited and automotive qualification is not required. |
| 1.5KE10A | Same DO-15 package and 600W rating, but non-AEC-Q101; VBR 9.5–10.5V, VC = 14.5V @ 10A | Lacks automotive stress validation; used in industrial power supplies and telecom infrastructure | Choose for cost-sensitive industrial designs where AEC-Q101 is unnecessary. |
Compared with SMAJ10A and 1.5KE10A, the P6KE10H provides guaranteed AEC-Q101 compliance and tighter VBR tolerance (±10% vs ±5.5% for 1.5KE10A), making it the only option qualified for automotive safety-critical power rail protection without additional qualification effort.

FAQ
What is the maximum clamping voltage of the P6KE10H under surge conditions?
The P6KE10H clamps to a maximum of 15.0 V when subjected to a 10 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during a full 600W transient event, ensuring compatibility with 16V-tolerant automotive ICs.
Is the P6KE10H suitable for bidirectional signal line protection?
No, the P6KE10H is a unidirectional TVS diode and must not be used on bidirectional lines such as RS-485 or USB data pairs. Its cathode-anode polarity is fixed, and reverse conduction is not specified. For bidirectional protection, select the P6KE10CA variant, which is explicitly rated for symmetrical clamping in both directions.
Does the P6KE10H require a heatsink in typical automotive applications?
No external heatsink is required for the P6KE10H under single-event surge conditions due to its short-duration energy absorption (10/1000 μs). However, in repetitive surge environments exceeding 1 Hz, thermal derating per Figure 2 of the datasheet must be applied, and PCB copper area ≥5 × 5 mm per lead is recommended to maintain TJ ≤175°C.
How does the AEC-Q101 qualification of the P6KE10H differ from standard industrial TVS diodes?
The P6KE10H undergoes accelerated stress testing per AEC-Q101-including 1000 cycles of temperature cycling (–55°C to +150°C), 1000 hours of high-temperature reverse bias, and mechanical shock-ensuring reliability in automotive under-hood environments. Standard industrial TVS diodes like the 1.5KE10A omit these validations and are not approved for safety-critical vehicle subsystems.
What is the meaning of the "H" suffix in P6KE10H?
The "H" suffix in P6KE10H denotes full AEC-Q101 qualification per Revision D, covering all stress tests required for automotive discrete semiconductors. This designation appears only on P6KE parts from 10V through 440V (excluding 6.8V–9.1V variants), and confirms that the specific P6KE10H lot has passed qualification-not just the family design.
