Product details
Overview
P6KE220 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 nominal breakdown voltage of 220 V, clamps transients to ≤344 V at 1.8 A peak pulse current, and delivers fast response (<1.0 ps from 0 V to VBR), low dynamic impedance, and <1 µA reverse leakage at 175 V standoff voltage - deployed in automotive lighting control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE220 datasheet, P6KE220 pinout, P6KE220 application, or P6KE220 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity marking, 175 °C maximum junction temperature, and compliance with AEC-Q101 (when ordered as P6KE220H), making it suitable for high-reliability 24/48 V DC systems requiring robust ESD and EFT immunity.
Technical Context
The P6KE220 operates as a silicon avalanche diode optimized for clamping high-energy transients per the 10/1000 µs waveform standard. Its unidirectional configuration enables asymmetric protection with cathode-band polarity, and its 220 V nominal breakdown (VBR = 198–242 V @ 1 mA) ensures precise voltage thresholding above system operating rails while maintaining low leakage (<1 µA @ 175 V).
Thermal performance is defined by a 175 °C maximum junction temperature and derating curves supporting operation up to 125 °C ambient. The device's 600 W non-repetitive peak pulse power rating is validated under JEDEC-standard test conditions, with mechanical construction meeting UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V @ 1 mA - defines reliable conduction onset window for overvoltage detection |
| VWM | 175 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |

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 SMAJ220A | Same DO-214AC (SMA) package; lower PPK (400 W); VC = 356 V @ 1.7 A | Suitable for space-constrained PCBs but requires derating in high-energy surge environments | Select when footprint size is critical and surge energy is ≤400 W; verify thermal margin in sealed enclosures |
| ON Semiconductor 1.5KE220A | Same DO-201AD package; identical 600 W rating; VC = 344 V @ 1.8 A; AEC-Q101 not available | Drop-in replacement for legacy designs using 1.5KE series; lacks automotive qualification | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with Littelfuse SMAJ220A and ON Semi 1.5KE220A, the P6KE220 offers superior surge energy handling in axial through-hole form factor and optional AEC-Q101 qualification - critical for automotive and harsh-environment deployments where board-level reliability and thermal robustness are prioritized over miniaturization.

FAQ
What is the maximum clamping voltage of the P6KE220 under standard surge conditions?
The P6KE220 clamps to a maximum of 344 V when subjected to a 10/1000 µs waveform with a peak pulse current of 1.8 A. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during transient events - critical for ensuring compatibility with 300 V-rated capacitors and 350 V MOSFETs in the same power stage.
Is the P6KE220 unidirectional or bidirectional, and how is polarity identified?
The P6KE220 is a unidirectional TVS diode, indicated by a cathode band marking on the DO-204AC (DO-15) package body. The banded end connects to the higher-potential side (e.g., 24 V rail), while the unbanded end connects to ground. Bidirectional variants carry "CA" suffixes (e.g., P6KE220CA), which the P6KE220 does not have.
Does the P6KE220 meet automotive qualification standards?
Yes - the P6KE220H variant is AEC-Q101 qualified for automotive applications, including under-hood environments. Standard P6KE220 parts are not AEC-Q101 certified; qualification applies only to ordering codes ending in "H". Always specify P6KE220H for automotive designs requiring formal reliability validation.
What is the standoff voltage (VWM) of the P6KE220, and why does it matter?
The P6KE220 has a maximum working voltage (VWM) of 175 V, meaning it remains in high-impedance state below this DC or RMS voltage, drawing less than 1 µA leakage current. This parameter ensures no interference with normal 220 V nominal systems operating at ≤175 V, such as 125 V AC-derived DC supplies or regulated 150 V intermediate rails.
Can the P6KE220 be used in surface-mount designs?
No - the P6KE220 uses a DO-204AC (DO-15) axial through-hole package and is not compatible with SMT assembly. For surface-mount equivalents, consider the SMAJ220A (DO-214AC) or SMCJ220A (DO-214AB), which offer similar voltage ratings but differ in power rating, package size, and thermal dissipation characteristics.
