Product details
Overview
P6KE160 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 160V nominal breakdown voltage (VBR min/max: 144V–176V), 130V standoff voltage (VWM), clamps to ≤230V at 2.7A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input stages.
For engineers reviewing the P6KE160 datasheet, P6KE160 pinout, P6KE160 application, or P6KE160 equivalent, key selection criteria include its 10/1000μs waveform surge rating, low dynamic impedance, sub-1ps response time from 0V to VBR, and AEC-Q101 qualification option (P6KE160H) for automotive-grade reliability validation.
Technical Context
The P6KE160 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range. Its junction structure delivers fast clamping action with typical IR <1μA at 130V, enabling low-leakage standby operation in high-impedance circuits.
Thermal design relies on derating per Fig.2: full 600W surge capability applies only at TA = 25°C, decreasing linearly to ~300W at 75°C ambient. The device sustains 100A non-repetitive forward surge (IFSM) but is rated for unidirectional use only - bidirectional variants require CA suffix (e.g., P6KE160CA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin |
| VBR (min/max) | 144 V / 176 V - Breakdown occurs within this range at 1 mA test current; ensures consistent trigger threshold across production lot |
| VC @ IPP | 230 V at 2.7 A - Clamped voltage during 10/1000μs surge; determines protected circuit's maximum transient exposure |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; defines single-event surge survivability |
| TJ max | +175 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without forced cooling |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with 0.400 g mass; compatible with standard wave-soldering processes |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line (e.g., GND or return path) |
| Cathode | Avalanche clamping terminal | Connected to higher-potential side (e.g., +12V rail); marked by band; conducts during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Surge robustness | 600W peak pulse power at 10/1000μs - withstands IEC 61000-4-5 Level 4 surges without degradation |
| Clamping speed | Typically <1.0 ps response from 0V to VBR - faster than most microcontroller GPIO protection requirements |
| Leakage control | IR <1 μA at VWM = 130V - avoids loading high-impedance sensor bias networks or battery-monitoring dividers |
| Thermal stability | 0.108 %/°C VBR tempco - predictable voltage shift over -55°C to +175°C operating range |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary TVS clamp placed upstream of DC-DC converter input filter.

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 SMAJ160A | Same DO-214AC (SMA) package; 160V VBR, 230V [email protected]; 400W PPK rating | Lower surge rating requires parallel placement for 600W compliance; surface-mount only | Select when PCB space constraints favor SMD and total surge energy is ≤400W |
| ON Semiconductor 1.5KE160A | DO-201AD package; identical 160V VBR, 230V [email protected]; same 600W PPK; higher IFSM (200A) | Larger footprint (7.1mm body vs. DO-15's 4.2mm); higher thermal mass improves repetitive surge tolerance | Select when mechanical robustness and repeated surge cycling are critical, and axial lead spacing allows DO-201AD mounting |
Compared with P6KE160, SMAJ160A offers SMD compatibility but sacrifices 200W surge headroom, while 1.5KE160A provides identical electrical specs in a physically larger, thermally superior package - making it preferable for high-cycle industrial environments where DO-201AD layout is feasible.

FAQ
What is the maximum clamping voltage of P6KE160 under standard surge conditions?
The P6KE160 clamps to a maximum of 230 V when subjected to a 10/1000 μs waveform with a peak surge current of 2.7 A. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during a defined transient event - critical for ensuring protected ICs remain within their absolute maximum ratings.
Is P6KE160 suitable for bidirectional transient protection?
No, P6KE160 is a unidirectional TVS diode intended for DC line protection with defined polarity. For bidirectional applications such as AC lines or data buses, the P6KE160CA variant must be used - it features symmetrical breakdown in both directions and is explicitly designated for bipolar operation in the datasheet.
Does P6KE160 meet automotive qualification standards?
The base P6KE160 is not AEC-Q101 qualified; however, the P6KE160H variant - identified by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested per stress conditions including temperature cycling, humidity bias HAST, and ESD. Always verify the full part number suffix when selecting for automotive use.
What is the thermal derating behavior of P6KE160 above 25°C ambient?
P6KE160 follows a linear derating curve: its 600W peak pulse power rating decreases by approximately 5.3W/°C above 25°C, reaching ~300W at 75°C ambient. This derating is defined in Fig.2 of the datasheet and must be applied when designing for enclosed or high-temperature environments to ensure reliable surge survival.
How does the junction capacitance of P6KE160 affect high-frequency signal line protection?
P6KE160 exhibits low junction capacitance (<100 pF at VR = 0 V, f = 1 MHz), making it suitable for protecting low-speed digital lines and DC power rails. However, it is not recommended for high-speed data lines (e.g., USB 2.0, HDMI) where sub-10 pF capacitance is required - in those cases, specialized low-capacitance TVS arrays or ESD suppressors should be selected instead of P6KE160.
