Product details
Overview
P6KE10A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a nominal breakdown voltage of 10 V, maximum clamping voltage of 14.5 V at 43 A peak surge current, and stand-off voltage of 8.55 V - enabling reliable protection of 9 V–12 V logic and interface circuits against IEC 61000-4-5 surges. Used in automotive body control modules, industrial PLC I/O protection, and AC/DC adapter input stages.
For engineers reviewing the P6KE10A datasheet, P6KE10A pinout, P6KE10A application, or P6KE10A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 1 μA max reverse leakage at 8.55 V, sub-1 ps response time from 0 V to VBR, and AEC-Q101 qualification eligibility (P6KE10A-H variant available).
Technical Context
The P6KE10A operates as a silicon avalanche diode with tightly controlled VBR (9.50–10.5 V at 1 mA test current), ensuring precise clamping onset before downstream IC damage. Its low dynamic impedance and fast 1 ps response enable effective suppression of ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) transients without affecting signal integrity.
Thermal design is supported by a 175 °C maximum junction temperature and derating curves for pulse width and ambient temperature per Fig.2. The device uses a single-die construction in a DO-204AC package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage; ensures no conduction during normal 9 V rail operation. |
| VBR (min/max) | 9.50 V / 10.5 V at 1 mA - Tight 10% tolerance enables predictable clamping threshold across temperature and lot variation. |
| VC @ IPP | 14.5 V at 43 A - Clamped voltage under 10/1000 µs surge; keeps protected ICs below absolute maximum ratings. |
| PPK | 600 W - Peak pulse power handling per 10/1000 µs waveform; meets IEC 61000-4-5 Level 4 (4 kV) requirements. |
| IR @ VWM | <1 µA - Negligible standby leakage; avoids battery drain in always-on 12 V systems. |
| Response Time | <1.0 ps - Avalanche turn-on speed from 0 V to VBR; faster than most ESD events (typically 100–500 ps). |
| TJMAX | 175 °C - High junction temperature rating supports under-hood automotive placement and high-ambient industrial use. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Dimensions per JEDEC DO-15 standard: overall length 25.4 mm ±0.5 mm, body diameter 3.6 mm ±0.2 mm, lead diameter 0.6 mm ±0.05 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; forms clamping loop with cathode to protect upstream components. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option | P6KE10A-H variant available for automotive applications requiring stress-tested reliability per Grade 0/1 conditions. |
| Low clamping ratio (VC/VBR) | 1.45 (14.5 V / 10 V) - Minimizes overvoltage overshoot during surge, critical for 3.3 V/5 V logic interfacing via level shifters. |
| UL 94V-0 flammability rating | Molding compound self-extinguishes within 10 seconds after flame removal - required for enclosed industrial enclosures. |
| Halogen-free construction | Complies with IEC 61249-2-21 - eliminates brominated flame retardants for RoHS-compliant and eco-friendly end-of-life processing. |
| 100% surge-tested screening | Each unit validated for 600 W pulse capability per 10/1000 µs waveform - guarantees robustness without batch sampling. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
|
Use Scenario: 12 V supply rail in BCM exposed to load dump (ISO 7637-2 Pulse 5a, up to 60 V/100 ms) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between fuse and LDO regulator input to limit transient voltage before regulation stage. Use Value: Clamps 60 V load dump to ≤14.5 V, preventing LDO thermal shutdown and preserving MCU boot sequence integrity. |
Use Scenario: 24 V digital input channel on PLC backplane subjected to field-wiring ESD and inductive kickback from solenoid coils. IC Role / Device Role / Timing Role: Front-end TVS placed before optocoupler input to absorb >4 kV contact ESD per IEC 61000-4-2 without degrading isolation barrier. Use Value: Sub-1 ps response prevents optocoupler LED overstress; 1 µA leakage avoids false triggering in high-impedance sensing circuits. |
| AC/DC Adapter Input Stage | USB-C Power Delivery Line Protection |
|
Use Scenario: Secondary-side 12 V output of flyback converter subjected to surge coupling from primary side and external cable transients. IC Role / Device Role / Timing Role: Secondary-rail TVS connected between +12 V and GND, downstream of output capacitor, to clamp coupled surges before DC-DC post-regulator. Use Value: 600 W rating handles coupled 1 kV/500 A surges; DO-15 package allows manual rework and fits tight board spacing near connector. |
Use Scenario: VBUS line in USB-C receptacle exposed to hot-plug transients and accidental 20 V PD negotiation faults. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBUS and GND to clamp overvoltage while allowing normal 5–20 V PD negotiation. Use Value: 8.55 V VWM permits full 5–20 V PD range; 14.5 V VC protects USB-C controller's 16 V absolute max rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ10A | Same DO-214AC (SMA) package; 10.0–11.1 V VBR, 17.0 V VC @ 35.3 A - higher clamping voltage, lower surge current rating (400 W). | Requires PCB redesign due to surface-mount SMA package; unsuitable for through-hole legacy designs. | Select if SMT assembly is mandatory and 17 V clamping is acceptable for protected ICs. |
| ON Semiconductor 1.5KE10A | Same DO-204AC (DO-15) package; identical VBR (9.5–10.5 V) and VC (14.5 V), but rated for 1500 W (1.5 kW) peak power. | Over-specified for 600 W needs; may increase cost and board space without functional benefit in typical 12 V rail protection. | Select only where future-proofing for higher-energy surges (e.g., ISO 16750-2) is required and cost premium is justified. |
Compared with SMAJ10A, P6KE10A offers lower clamping voltage and through-hole compatibility; compared with 1.5KE10A, it provides optimal cost-performance balance for standard 600 W IEC 61000-4-5 compliance without over-engineering.

FAQ
What is the maximum clamping voltage of the P6KE10A under surge conditions?
The P6KE10A has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 43 A using the 10/1000 µs waveform. This value is guaranteed across temperature and process variation per the datasheet's electrical specifications table and is measured at the device terminals under standardized test conditions.
Is the P6KE10A suitable for bidirectional transient protection?
No, the P6KE10A is a unidirectional TVS diode intended for DC line protection with polarity-sensitive mounting (cathode to the protected line). For bidirectional protection, the P6KE10CA variant must be used - it features symmetrical breakdown in both directions and lacks a cathode band marking.
Does the P6KE10A meet automotive qualification standards?
The base P6KE10A is not AEC-Q101 qualified, but the P6KE10A-H variant - identifiable by the "H" suffix in the ordering code - is fully AEC-Q101 qualified for automotive Grade 0 and Grade 1 temperature ranges and undergoes accelerated stress testing per the standard's requirements.
What is the reverse leakage current of the P6KE10A at its stand-off voltage?
The P6KE10A exhibits a maximum reverse leakage current (IR) of 1 µA when biased at its rated stand-off voltage (VWM) of 8.55 V. This low leakage ensures minimal power loss in battery-powered or energy-sensitive 12 V systems where quiescent current matters.
Can the P6KE10A be used in place of the P6KE10 without modification?
Yes, the P6KE10A replaces the P6KE10 with tighter VBR tolerance (±5% vs. ±10%), lower clamping voltage (14.5 V vs. 15.0 V), and improved consistency - all while maintaining identical DO-204AC packaging, pinout, and thermal characteristics. No PCB or schematic changes are needed for drop-in replacement.
