Product details
Overview
P6KE15 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 15 V, clamps transients to ≤22.0 V at 28.0 A peak surge current, and maintains <1 μA reverse leakage at its 12.1 V stand-off voltage - enabling robust ESD and lightning surge protection in automotive body electronics and industrial control I/O modules.
For engineers reviewing the P6KE15 datasheet, P6KE15 pinout, P6KE15 application, or P6KE15 equivalent, key selection criteria include its DO-15 package compatibility, 10/1000 µs waveform surge rating, unidirectional polarity marking, and temperature coefficient of 0.084 %/°C - all critical for layout-integrated transient suppression in space-constrained 12 V systems.
Technical Context
The P6KE15 operates as a silicon avalanche diode with a single-die DO-204AC (DO-15) construction, optimized for fast clamping response (<1.0 ps rise time from 0 V to VBR) and low dynamic impedance. Its junction temperature range spans −55 °C to +175 °C, supporting under-hood automotive deployment without derating below 75 °C ambient.
Electrical behavior follows ANSI/IEEE C62.35 standards: breakdown voltage is measured after 300 µs square-wave IT pulse; clamping voltage VC is specified at IPP = 28.0 A with 10/1000 µs waveform; and thermal derating follows Fig.2 - reducing peak power linearly above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 13.5 V / 16.5 V - ensures reliable avalanche conduction onset across manufacturing lot and temperature variation |
| VWM | 12.1 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| IPP | 28.0 A - peak surge current it safely shunts during 10/1000 µs transient events (e.g., ISO 7637-2 Pulse 1/2a) |
| VC@IPP | 22.0 V - clamped voltage seen by protected circuitry during full-rated surge, defining minimum system overvoltage margin |
| PPK | 600 W - non-repetitive peak pulse power handling capability per standard 10/1000 µs waveform |
| TJMAX | +175 °C - maximum junction temperature allowing operation in high-ambient environments like engine control units |
| Package | DO-204AC (DO-15) - axial-leaded through-hole package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case rated UL 94V-0; cathode indicated by band marking; lead spacing 5.0 mm min; weight ≈0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest-potential node in unidirectional configuration; defines current path during clamping |
| Cathode | High-side transient input terminal | Marked with band; connects to protected line (e.g., 12 V rail); conducts avalanche current to anode when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification option (P6KE15H) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Clamping ratio (VC/VBR) | ≤1.63 - low overvoltage overshoot during surge, preserving downstream IC voltage tolerances |
| Dynamic impedance (Zdynamic) | ~0.36 Ω - calculated as (VC − VBR)/IPP; enables effective energy diversion with minimal voltage rise |
| Reverse leakage at VWM | <1 μA - negligible standby power loss and no measurable impact on high-impedance sensor bias networks |
| Fast response time | <1.0 ps - sub-nanosecond turn-on ensures suppression before sensitive logic or analog circuits experience overstress |
Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Digital Input Protection |
|---|---|
|
Use Scenario: 12 V battery-fed microcontroller power rail exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp surges before LDO regulator input. Use Value: Limits voltage to ≤22.0 V during 28 A surge, preventing LDO overvoltage failure and maintaining MCU brown-out reset integrity. |
Use Scenario: 24 V digital input channel receiving signals from field sensors subject to EFT bursts per IEC 61000-4-4. IC Role / Device Role / Timing Role: Standoff protection device mounted at connector entry point to absorb fast transients before optocoupler input. Use Value: Sub-1 ns response captures EFT edges; 12.1 V VWM ensures no false triggering during normal 24 V ±10% operation. |
| LED Driver Supply Line Protection | RS-485 Transceiver VCC Rail Clamp |
|
Use Scenario: Constant-current LED driver powered from 12 V vehicle supply with inductive switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on driver IC's VCC pin to prevent latch-up during inductive kickback. Use Value: 600 W surge rating handles repetitive coil-switching spikes; DO-15 footprint allows direct placement near driver IC. |
Use Scenario: RS-485 transceiver IC operating from isolated 5 V supply in noisy factory automation environment. IC Role / Device Role / Timing Role: Unidirectional TVS on transceiver VCC rail to suppress coupled common-mode surges entering via bus termination. Use Value: Clamps to 22.0 V while maintaining <1 μA leakage - avoids loading low-current isolated supply and preserves bus fault tolerance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A (Bourns) | DO-214AA package; 600 W rating; bidirectional variant available; VC = 24.4 V @ 24.7 A | Surface-mount footprint requires PCB redesign; higher clamping voltage reduces margin for 15 V logic rails | Select when SMT assembly is mandatory and board space prohibits axial DO-15 placement |
| 1.5KE15A (ON Semiconductor) | Same DO-15 package; identical VBR (13.5–16.5 V); VC = 22.5 V @ 27.3 A; RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial but not automotive production programs | Select for cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with SMBJ15A and 1.5KE15A, the P6KE15 offers identical form-factor compatibility with legacy DO-15 layouts, tighter clamping (22.0 V), and optional AEC-Q101 qualification - making it the preferred choice for new automotive designs requiring drop-in reliability upgrades.

FAQ
What is the maximum clamping voltage of the P6KE15 under full-rated surge conditions?
The P6KE15 clamps to a maximum of 22.0 V when subjected to its rated 28.0 A peak pulse current (IPP) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KE15 suitable for bidirectional transient protection?
No, the standard P6KE15 is unidirectional and must be installed with correct polarity (cathode toward the protected line). For bidirectional protection, select the P6KE15CA variant - which uses a center-tapped dual-diode configuration and is explicitly designated for AC or bipolar signal line protection per the manufacturer's ordering table.
Does the P6KE15 meet automotive qualification requirements?
The base P6KE15 is not AEC-Q101 qualified; however, the P6KE15H variant - identifiable by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested for automotive applications including temperature cycling, high-temperature reverse bias, and ESD robustness per the standard's stress test plan.
What is the standoff voltage (VWM) and why does it matter for P6KE15 circuit design?
The P6KE15 has a maximum working peak voltage (VWM) of 12.1 V, meaning it reliably blocks voltages up to this level without significant leakage (<1 µA). This parameter defines the highest continuous DC or RMS voltage the device can withstand - essential for ensuring no false triggering in 12 V systems and avoiding unnecessary power loss in always-on circuits.
How does the P6KE15 compare to the P6KE15A variant?
The P6KE15A offers tighter breakdown voltage tolerance (14.3–15.8 V vs. 13.5–16.5 V for P6KE15) and slightly lower clamping voltage (21.2 V vs. 22.0 V), resulting in improved overvoltage margin for precision 15 V rails. Both share identical package, surge rating, and thermal specs - making P6KE15A preferable where tighter VBR distribution is required.
