Product details
Overview
P6KE350 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supplies and industrial control interfaces. It features a nominal breakdown voltage of 350 V, clamps transients to ≤504 V at 1.2 A peak surge current, exhibits <1 μA reverse leakage at 284 V standoff voltage, and uses a DO-204AC (DO-15) axial package for through-hole mounting in AC/DC front-end circuits.
For engineers reviewing the P6KE350 datasheet, P6KE350 pinout, P6KE350 application, or P6KE350 equivalent, key selection criteria include its 315–385 V breakdown range, 10/1000 µs 600 W surge rating, low dynamic impedance, fast sub-nanosecond response, and AEC-Q101 qualification option - all critical for robust ESD and lightning surge immunity in automotive and industrial power rails.
Technical Context
The P6KE350 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range (315–385 V at 1 mA test current). Its clamping action limits transient energy to ≤504 V at 1.2 A peak pulse current under standardized 10/1000 µs waveform conditions.
Thermal derating begins above 25°C ambient, with maximum junction temperature rated at +175°C and steady-state power dissipation of 5 W at 75°C on 5×5 mm copper pads. It complies with ANSI/IEEE C62.35 for surge testing and meets UL 94V-0 flammability requirements in its molded DO-204AC package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 350 V - defines mid-point of breakdown range used for system-level voltage margining |
| Breakdown Voltage VBR | 315–385 V at 1 mA - ensures reliable conduction onset across manufacturing tolerance and temperature |
| Standoff Voltage VWM | 284 V - maximum continuous reverse voltage before significant leakage; sets operating margin below VBR |
| Peak Pulse Power PPK | 600 W at 10/1000 µs - sustains high-energy surges without failure in telecom or industrial AC line protection |
| Clamping Voltage VC | ≤504 V at 1.2 A - limits downstream IC stress during worst-case transients per IEC 61000-4-5 |
| Reverse Leakage ID | <1 µA at 284 V - minimizes standby power loss and avoids false triggering in high-impedance sensing nodes |
| Junction Temperature | −55°C to +175°C - supports operation in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Meets JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or return path; forms avalanche junction with cathode |
| Cathode | High-side transient clamp node | Connected to protected line (e.g., AC input or DC bus); conducts surge current to ground when VREV > VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W surge capability | Withstands 10/1000 µs transients up to 600 W without degradation - suitable for Level 4 IEC 61000-4-5 compliance |
| Fast response time | <1.0 ps from 0 V to VBR - clamps ESD and fast-rising spikes before sensitive downstream components react |
| Low dynamic impedance | Enables tight clamping voltage window (VC − VBR ≈ 150 V) - reduces voltage overshoot during surge events |
| AEC-Q101 qualified option | Available as P6KE350H - validated for automotive powertrain and body electronics per stress-test requirements |
| UL recognition | File #E-326243 - confirms safety compliance for end-equipment certification in North America |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ350A | Same DO-214AC (SMA) package; 350 V nominal, 504 V clamping at 1.2 A; 400 W rating | Lower surge rating requires parallel placement for 600 W compliance; surface-mount only | Select when board space constraints favor SMD or when lower cost offsets need for higher surge headroom |
| ON Semiconductor 1.5KE350A | Same DO-201AD (DO-27) axial package; identical 350 V nominal, 504 V clamping, but 1500 W rating | Higher surge capacity enables single-device coverage for harsher environments (e.g., utility metering) | Select when future-proofing against higher surge test levels or extending lifetime in high-cycle industrial settings |
Compared with P6KE350, SMAJ350A offers compact SMD packaging but reduced surge handling, while 1.5KE350A delivers triple the peak power in a larger axial form factor - enabling trade-offs between layout density, reliability margin, and mechanical mounting requirements.

FAQ
What is the breakdown voltage range of the P6KE350?
The P6KE350 has a guaranteed breakdown voltage (VBR) range of 315 V to 385 V at 1 mA test current, measured per ANSI/IEEE C62.35. This 70 V spread reflects process tolerance and ensures reliable turn-on across temperature and unit-to-unit variation while maintaining safe margin below its 504 V clamping voltage.
Is the P6KE350 unidirectional or bidirectional?
The P6KE350 is a unidirectional TVS diode, indicated by its single cathode band marking and specification of VBR and VWM only for reverse bias. It is not rated for symmetrical bipolar operation - for bidirectional protection, the P6KE350A variant must be selected instead.
Does the P6KE350 meet automotive qualification standards?
The base P6KE350 is not AEC-Q101 qualified; however, the P6KE350H variant - identifiable by the "H" suffix - is fully AEC-Q101 qualified and tested for automotive applications including body electronics and infotainment power rails. Always verify the full part number suffix before automotive use.
What is the maximum clamping voltage of the P6KE350 at rated surge current?
The P6KE350 clamps to a maximum of 504 V when subjected to its rated peak pulse current of 1.2 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the P6KE350 be used in surface-mount designs?
No - the P6KE350 uses a DO-204AC (DO-15) axial leaded package intended for through-hole mounting. For surface-mount equivalents, consider the SMAJ350A (DO-214AC) or SMCJ350A (DO-214AB), which share similar electrical specs but differ in package size, thermal performance, and surge rating.
