Product details
Overview
P6KE16 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 16 V, clamps transients to ≤23.5 V at 26 A peak surge current (10/1000 µs), and maintains <1 µA reverse leakage above 12.9 V standoff voltage - deployed in automotive body control modules, industrial PLC I/O protection, and LED driver input stages.
For engineers reviewing the P6KE16 datasheet, P6KE16 pinout, P6KE16 application, or P6KE16 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 175°C maximum junction temperature, and compliance with AEC-Q101 (when ordered as P6KE16H), making it suitable for high-reliability 12 V system surge immunity design.
Technical Context
The P6KE16 operates as a silicon avalanche diode optimized for fast clamping of ESD and lightning-induced transients. Its low dynamic impedance ensures minimal voltage overshoot during 10/1000 µs surges, while its <1.0 ps response time from 0 V to VBR enables effective suppression before downstream ICs experience stress.
It is rated for non-repetitive 600 W peak pulse power, derates linearly above 25°C ambient per Fig.2, and supports steady-state dissipation of 5 W at 75°C with 9.5 mm lead length copper pads. The device exhibits a +0.086 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across automotive and industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges without failure, e.g., ISO 7637-2 Pulse 1/2a/5a |
| Breakdown Voltage VBR | 14.4–17.6 V @ 1 mA - defines precise avalanche initiation threshold for reliable clamping onset |
| Standoff Voltage VWM | 12.9 V - maximum continuous DC or RMS voltage the device blocks without conduction |
| Clamping Voltage VC | 23.5 V @ 26 A - limits transient voltage seen by protected circuitry to safe levels |
| Reverse Leakage ID | <1 µA @ 12.9 V - negligible standby current, critical for low-power battery-backed systems |
| Junction Temperature Range | −55°C to +175°C - supports under-hood automotive and industrial environments without thermal derating loss |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with through-hole assembly and manual rework |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking on one end; 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 | Low-side connection to protected circuit ground or return path | Completes clamping path during transient events; must be routed with low-inductance trace to ground plane |
| Cathode | High-side connection to line being protected (e.g., 12 V rail) | Marked with band; connects to vulnerable node - clamps to anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option (P6KE16H) | Validated for automotive applications including engine control, lighting, and infotainment power rails |
| 600 W surge capability (10/1000 µs) | Withstands ISO 7637-2 Pulse 5a (500 V/2 Ω) without degradation in 12 V systems |
| Clamping voltage ≤23.5 V at 26 A | Keeps downstream 3.3 V/5 V logic ICs within absolute maximum ratings during surge events |
| Ultra-fast response: <1.0 ps (0 V → VBR) | Activates before most microcontroller I/O pins can be damaged by ESD or EFT bursts |
| RoHS & halogen-free (IEC 61249-2-21) | Complies with global environmental regulations and enables use in consumer and medical-grade assemblies |
Applications
| Automotive Lighting Systems | Industrial PLC Digital Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A (Bourns) | Same 16 V nominal, but SMC package (surface-mount); 600 W rating; slightly lower VC = 24.4 V @ 24.5 A | Requires PCB redesign for SMD placement; better for automated assembly and space-constrained layouts | Select SMBJ16A when board real estate is limited and reflow compatibility is required. |
| 1.5KE16A (ON Semiconductor) | Same DO-15 package and 16 V rating; identical VBR range (14.4–17.6 V); VC = 23.5 V @ 26 A - functionally matched | No AEC-Q101 qualification available; not validated for automotive temperature cycling or humidity testing | Choose 1.5KE16A for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ16A and 1.5KE16A, the P6KE16 offers identical clamping performance in a through-hole package with optional AEC-Q101 qualification (as P6KE16H), making it optimal for prototyping, repair, and automotive-grade designs requiring mechanical robustness and qualification traceability.

FAQ
What is the maximum clamping voltage of the P6KE16 under surge conditions?
The P6KE16 clamps to a maximum of 23.5 V when subjected to a 26 A peak surge current with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and ensures protected downstream components - such as 24 V-rated logic ICs or 3.3 V LDOs with 30 V abs max - remain within safe operating limits during transient events.
Is the P6KE16 unidirectional or bidirectional, and how is polarity identified?
The P6KE16 is a unidirectional TVS diode, with polarity indicated by a cathode band marked on the DO-204AC (DO-15) package body. The banded end connects to the protected line (e.g., 12 V rail), while the unbanded end connects to ground - enabling clamping only for positive transients relative to ground.
Does the P6KE16 meet automotive qualification standards?
The base P6KE16 is not AEC-Q101 qualified; however, the variant P6KE16H - identifiable by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested for temperature cycling, humidity bias, and mechanical shock. This makes P6KE16H suitable for under-hood and body-control applications.
What is the standoff voltage (VWM) of the P6KE16, and why does it matter?
The P6KE16 has a maximum standoff voltage (VWM) of 12.9 V, meaning it remains non-conductive below this DC or RMS voltage. This parameter ensures no leakage current flows during normal operation - critical for maintaining efficiency in always-on 12 V systems like automotive telematics or smart sensors.
Can the P6KE16 replace the P6KE16A in a design?
No - the P6KE16 and P6KE16A are not interchangeable without validation. While both share the same nominal voltage (16 V), the P6KE16A has tighter VBR tolerance (15.2–16.8 V vs. 14.4–17.6 V) and lower clamping voltage (22.5 V @ 28 A). Substituting requires checking whether the design margin accommodates the higher VC and wider VBR of the P6KE16.
