Product details
Overview
P6KE160H 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 160 V, maximum clamping voltage of 230 V at 2.7 A peak surge current, and stand-off voltage of 130 V - enabling robust ESD and lightning-induced surge suppression in automotive and industrial control systems.
For engineers reviewing the P6KE160H datasheet, P6KE160H pinout, P6KE160H application, or P6KE160H equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-reliability PCB layouts, low dynamic impedance (<1 Ω typical), sub-1 ps response time, and 175°C junction temperature rating for under-hood deployment.
Technical Context
The P6KE160H operates as a silicon avalanche diode optimized for unidirectional clamping. Its breakdown voltage (VBR) is specified at 144–176 V with 1 mA test current, and it delivers precise clamping at 230 V when subjected to a 10/1000 µs 2.7 A surge pulse. The device exhibits a temperature coefficient of VBR of 0.108 %/°C, ensuring stable threshold behavior across automotive ambient ranges.
It is rated for non-repetitive peak impulse power of 600 W, steady-state power dissipation of 5 W at 75°C (with 9.5 mm lead length), and withstands 100 A forward surge current (8.3 ms half-sine). Polarity is marked by a cathode band, and leakage current remains below 1 µA at 130 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12–48 V systems with transients. |
| VBR (min/max) | 144 V / 176 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC @ IPP | 230 V at 2.7 A - Clamping voltage during 10/1000 µs surge; limits downstream IC stress to safe levels per IEC 61000-4-5 Level 4. |
| PPK | 600 W - Peak pulse power handling capacity; supports single-event surge immunity up to 2.7 A without degradation. |
| TJMAX | 175 °C - Maximum junction temperature; enables operation in engine bay or industrial enclosures without derating. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage at rated stand-off; preserves battery life and avoids false triggers in low-power monitoring circuits. |
| Response Time | <1.0 ps - Avalanche initiation speed from 0 V to VBR; faster than most ESD events (IEC 61000-4-2), ensuring pre-damage clamping. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94V-0 flammability rating. Cathode indicated by band-marked end; anode is unmarked lead. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Current entry point during forward conduction; grounded reference in unidirectional clamp configuration | Connected to system ground or low-impedance return path; forms clamping loop with cathode on protected line. |
| Cathode (banded lead) | Protected line connection; reverse-biased terminal during normal operation | Placed directly on input rail (e.g., 12 V battery feed); conducts only during overvoltage to shunt energy to ground. |
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 |
|---|---|---|---|
| SMBJ160A | DO-214AA package; 600 W rating; VBR = 178–197 V; VC = 259 V @ 2.3 A; higher clamping voltage | Surface-mount layout; requires rework for through-hole replacement; lower surge current tolerance (2.3 A vs. 2.7 A) | Select SMBJ160A only if board space constraints mandate SMD and clamping margin allows +29 V higher VC. |
| 1.5KE160A | DO-201AD package; same 160 V nominal; VC = 234 V @ 2.6 A; 1.5 kW peak power but larger footprint and higher thermal mass | Through-hole compatible but longer leads increase inductance; less suitable for fast-edge ESD due to parasitic L | Choose 1.5KE160A only when legacy designs require backward-compatible mechanical fit and higher single-pulse energy absorption is needed. |
Compared with P6KE160H, SMBJ160A offers SMT convenience at the cost of higher clamping and reduced surge current, while 1.5KE160A provides greater energy handling in a less compact through-hole form - making P6KE160H the optimal balance of AEC-Q101 compliance, DO-15 manufacturability, and precise 230 V clamping for automotive and industrial DC rails.

FAQ
What is the maximum clamping voltage of the P6KE160H under standard surge conditions?
The P6KE160H has a maximum clamping voltage (VC) of 230 V when subjected to a 10/1000 µs waveform with a peak surge current (IPP) of 2.7 A. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components in the P6KE160H protection circuit.
Is the P6KE160H suitable for bidirectional transient suppression?
No - the P6KE160H is a unidirectional TVS diode, indicated by its "H" suffix and cathode band marking. For bidirectional protection, Taiwan Semiconductor specifies CA-suffixed variants (e.g., P6KE160CA); using P6KE160H in AC or bipolar signal paths would result in forward conduction and potential failure.
Does the P6KE160H meet automotive qualification standards?
Yes - the "H" suffix explicitly denotes AEC-Q101 qualification per the manufacturer's ordering information. The P6KE160H undergoes stress testing for temperature cycling, mechanical shock, and high-temperature reverse bias, making it approved for use in automotive powertrain and body electronics.
What is the leakage current specification for the P6KE160H at its rated stand-off voltage?
At its maximum working voltage (VWM) of 130 V, the P6KE160H exhibits a maximum reverse leakage current (IR) of 1 µA at 25°C. This ultra-low leakage preserves efficiency in always-on systems and avoids false triggering in high-impedance sensing nodes protected by the P6KE160H.
How does the P6KE160H compare to the P6KE160A variant?
The P6KE160H and P6KE160A share identical electrical parameters (VBR, VC, PPK), but only the P6KE160H carries AEC-Q101 qualification. The "A" suffix indicates tighter VBR tolerance (±5% vs. ±10% for non-A parts), while "H" adds automotive reliability validation - so P6KE160H is the preferred choice for automotive applications requiring both precision and qualification.
