Product details
Overview
P6KE15C 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 15V nominal breakdown voltage (VBR min/max: 13.5V–16.5V), 12.1V stand-off voltage (VWM), clamps to ≤22.0V at 28A peak surge current, and operates within -55°C to +175°C junction temperature range.
For engineers reviewing the P6KE15C datasheet, P6KE15C pinout, P6KE15C application, or P6KE15C equivalent, key selection criteria include its DO-15 package compatibility, 10/1000μs waveform surge rating, low dynamic impedance, fast sub-nanosecond response, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE15C functions as a unidirectional avalanche diode that remains non-conductive below 12.1V (VWM) and enters controlled breakdown above 13.5V (VBR min), limiting transient energy by shunting surge current to ground. Its clamping voltage of 22.0V at 28A ensures downstream ICs experience minimal overvoltage during ESD or inductive switching events.
It complies with ANSI/IEEE C62.35 for transient suppression, exhibits <1μA reverse leakage above 10V, and maintains stable VBR with a temperature coefficient of 0.084%/°C - critical for thermal stability in automotive and industrial environments where ambient temperatures exceed 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.1 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 13.5 V / 16.5 V - Breakdown initiates reliably within this range at 1 mA test current |
| VC @ IPP | 22.0 V at 28 A - Peak clamped voltage during 10/1000μs surge, defining maximum stress on protected circuit |
| PPK | 600 W - Non-repetitive surge power handling capability per standard waveform |
| IR @ VWM | <1 μA - Negligible leakage current ensures minimal standby power loss and signal integrity |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads, UL 94V-0 rated molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical glass-passivated body with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side | Connected to protected line (e.g., 12V rail); conducts to cathode when transient exceeds VBR |
| Cathode | Ground reference | Connected to system ground; provides low-impedance path for surge current during clamping |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA package; bidirectional; 15V VWM; 24.4V VC @ 24.7A | Designed for PCB space-constrained layouts; supports bidirectional transients (e.g., AC-coupled lines) | Select SMBJ15A when board area is limited or bidirectional protection is required; P6KE15C offers higher surge rating in axial form factor. |
| 1.5KE15C | Same DO-15 package; 15V nominal; 22.5V VC @ 27.3A; 1500W rating | Higher power handling for extreme industrial surge environments (e.g., factory floor motor drives) | Choose 1.5KE15C for applications requiring >600W surge margin; P6KE15C balances cost, size, and AEC-Q101 compliance for automotive use. |
Compared with SMBJ15A and 1.5KE15C, the P6KE15C delivers AEC-Q101 qualification and optimized 600W clamping performance in the legacy DO-15 footprint - making it ideal for cost-sensitive, high-volume automotive and industrial replacements where proven reliability and axial lead assembly are preferred.

FAQ
What is the polarity configuration of the P6KE15C?
The P6KE15C is a unidirectional TVS diode with clearly marked cathode band. It conducts only when the anode is more positive than the cathode by ≥13.5V, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like P6KE15CA, which protect AC or reversible signal lines.
Does the P6KE15C meet automotive qualification standards?
Yes, the P6KE15C is AEC-Q101 qualified - verified through stress testing including high-temperature operating life, temperature cycling, and ESD robustness. This certification confirms its suitability for automotive applications such as body control modules, lighting systems, and infotainment power supplies.
What is the maximum clamping voltage of the P6KE15C under surge conditions?
The P6KE15C clamps to a maximum of 22.0V when subjected to a 28A peak surge current with a 10/1000μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the P6KE15C be used in place of the P6KE15A?
No - the P6KE15C and P6KE15A are distinct variants: P6KE15C has tighter VBR tolerance (13.5–16.5V) and is unidirectional, while P6KE15A specifies 14.3–15.8V VBR and is also unidirectional but optimized for lower leakage. Substitution requires validation of VBR window, leakage, and application-specific clamping requirements.
What packaging options are available for the P6KE15C?
The P6KE15C is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (P6KE15CH) and 1,500 units per ammo box (P6KE15CA0G). Both options feature pure tin-plated leads compliant with J-STD-002 solderability requirements.
