Product details
Overview
P4KE160 from Taiwan Semiconductor is a unidirectional 400W 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 working stand-off voltage (VWM), clamps transients to ≤230V at 1.8A peak pulse current, and delivers sub-nanosecond response for ESD and EFT immunity in automotive body electronics.
For engineers reviewing the P4KE160 datasheet, P4KE160 pinout, P4KE160 application, or P4KE160 equivalent, key selection criteria include its DO-41 package compatibility, 175°C junction rating, low leakage (<1μA @ 130V), and AEC-Q101 qualification path - critical for under-hood and lighting module surge protection design.
Technical Context
The P4KE160 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 144–176V breakdown range at 1mA test current. Its clamping action limits transient energy to ≤230V at 1.8A (10/1000μs waveform), sustaining 400W non-repetitive surge power without degradation.
Thermal performance is defined by a 175°C maximum junction temperature and 1W steady-state dissipation at 75°C lead temperature. The device exhibits a +0.108%/°C VBR temperature coefficient and <1μA reverse leakage above 130V, ensuring stable threshold behavior across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC operating voltage before conduction begins; sets safe margin below system rail. |
| VBR @ IT=1mA | 144–176 V - Breakdown voltage range defining reliable avalanche onset; ensures consistent triggering across units. |
| VC @ IPPM | 230 V - Clamped voltage at 1.8A peak pulse (10/1000μs); determines maximum stress on downstream ICs. |
| PPK | 400 W - Peak pulse power handling capacity; defines survivability against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <1 μA - Reverse leakage at stand-off voltage; minimizes quiescent power loss and avoids false triggering. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in high-ambient environments like engine compartments. |
| Package | DO-204AL (DO-41) - Industry-standard axial-leaded package with tin-plated leads; compatible with wave soldering per J-STD-002. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, glass-passivated silicon junction, cathode band marked on case end. Leads are pure tin-plated, compliant with JESD 201 Class 2 whisker resistance and UL 94V-0 flammability rating. Weight: 0.300g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return; completes conduction path during transient clamp event. |
| Cathode | Protected line input | Connected to protected node (e.g., 12V rail or CAN bus line); avalanche conduction occurs from cathode to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification path | Available in H-suffix variants (e.g., P4KE160H); supports automotive-grade reliability validation for body control modules. |
| Clamping ratio (VC/VBR) | ≤1.60 - Low ratio ensures minimal overvoltage overshoot during fast transients; improves IC survival margin. |
| Response time | <1.0 ps - Sub-picosecond turn-on enables suppression of ESD events (IEC 61000-4-2) before damage occurs. |
| Surge waveform compliance | Rated for 10/1000μs waveform per ANSI/IEEE C62.35 - matches real-world lightning-induced surges in automotive and industrial wiring. |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets environmental requirements for RoHS-compliant manufacturing and end-of-life processing. |

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 | Surface-mount SMB package (vs. axial DO-41); same 160V nominal, but lower 600W PPK rating and higher 243V VC. | Preferred for space-constrained PCBs; requires rework of layout and thermal pad design. | Select SMBJ160A only when board area is limited and higher clamping voltage is acceptable. |
| 1.5KE160A | Same DO-41 package and 160V rating, but 1500W PPK and 259V VC; larger junction, higher leakage (~5μA @ VWM). | Better for high-energy surges (e.g., ISO 7637-2 Pulse 5b), but less precise clamping for sensitive analog interfaces. | Choose 1.5KE160A where surge energy exceeds 400W but tighter clamping is not required. |
Compared with SMBJ160A and 1.5KE160A, the P4KE160 offers optimal balance of axial-package manufacturability, 400W surge capability, and low 230V clamping - making it ideal for cost-sensitive, high-volume automotive and industrial power rail protection where layout flexibility and thermal management via leads are advantageous.

FAQ
What is the maximum clamping voltage of the P4KE160 under standard surge conditions?
The P4KE160 clamps to a maximum of 230 V when subjected to a 1.8 A peak pulse current with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during transient events - a critical parameter for ensuring IC-level overvoltage safety margins in 12V and 24V systems.
Is the P4KE160 suitable for bidirectional transient protection?
No, the P4KE160 is a unidirectional TVS diode intended for DC line protection with defined polarity. For bidirectional applications such as AC lines or differential buses, the P4KE160A variant or dedicated bipolar parts like P4KE160CA must be used - the P4KE160 itself conducts only in reverse bias and will forward-conduct if positive voltage exceeds ~3.5V on its anode relative to cathode.
What does the "H" suffix mean in P4KE160H, and is it available through Aetrix Electronics?
The "H" suffix denotes AEC-Q101 qualification - indicating that the P4KE160H variant has undergone stress testing for automotive reliability, including temperature cycling, humidity bias HAST, and mechanical shock. While the base P4KE160 is standard-qualified, Aetrix Electronics stocks and supports the P4KE160H for automotive design-in and PPAP documentation upon request.
How does the P4KE160 compare to the 1.5KE160A in terms of physical compatibility and thermal performance?
The P4KE160 and 1.5KE160A share identical DO-41 packaging, lead finish, and mounting dimensions - enabling direct footprint reuse. However, the 1.5KE160A dissipates more heat due to its 1500W rating and larger die, requiring greater copper area for thermal relief. The P4KE160's 400W rating allows simpler thermal design with standard 5×5 mm pads per lead, per its datasheet derating curve.
Can the P4KE160 be used in parallel to increase surge current handling?
No - the P4KE160 should not be paralleled without external balancing resistors. Minor VBR tolerances (144–176V) cause uneven current sharing during transients, risking thermal runaway in the lower-VBR unit. For higher IPPM requirements, select a single higher-rated device (e.g., 1.5KE160A) or implement staged protection with series impedance.
