Product details
Overview
P4KE180C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 180V nominal standoff voltage, 162–198V breakdown range at 1mA test current, 146V working peak reverse voltage, 258V maximum clamping voltage at 1.6A peak pulse current, and 400W peak pulse power rating per 10/1000μs waveform - deployed in automotive lighting control, industrial PLC I/O protection, and telecom power supply input stages.
For engineers reviewing the P4KE180C datasheet, P4KE180C pinout, P4KE180C application, or P4KE180C equivalent, key selection criteria include bidirectional clamping behavior, DO-41 package compatibility with through-hole PCB layouts, low leakage (<1μA at 146V), fast response (<5ns), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P4KE180C operates as a bidirectional avalanche diode, symmetrically clamping transients above ±162V in either polarity without polarity marking dependency. Its junction structure enables sub-5ns response to EFT and lightning-induced surges while maintaining <1μA reverse leakage at rated VWM.
Rated for 175°C maximum junction temperature and compliant with ANSI/IEEE C62.35 surge standards, it delivers 258V clamping at 1.6A (10/1000μs), with temperature coefficient of VBR at 0.108%/°C - ensuring predictable voltage drift across industrial operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 146 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR min/max | 162 V / 198 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering across process variation and temperature |
| VC @ IPPM | 258 V at 1.6 A (10/1000μs) - Peak clamped voltage seen by protected circuit during worst-case surge event |
| PPK | 400 W - Surge energy handling capability per single 10/1000μs pulse; supports IEC 61000-4-5 Level 4 compliance |
| ID @ VWM | <1 μA - Ultra-low leakage preserves system standby power integrity and avoids false triggering in high-impedance nodes |
| TJ max | 175 °C - Enables operation in under-hood automotive and industrial environments without derating |
| Package | DO-204AL (DO-41) - Standard through-hole package with 0.300g mass; compatible with legacy wave-solder and hand-solder processes |
Pinout & Package

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 SMAJ180CA | Same DO-214AC (SMA) package; 180V VWM; 258V VC @ 1.6A; 400W rating; but unidirectional unless explicitly CA suffix | Requires explicit CA suffix for bidirectional use; SMA footprint differs from DO-41 - needs PCB redesign | Select when surface-mount assembly is preferred and board space is constrained; verify CA marking for bidirectional function |
| ON Semiconductor 1.5KE180CA | Higher 1.5kW peak power rating; same 180V VWM and bidirectional CA configuration; DO-201AE (DO-27) package | Physically larger package (5.6mm length vs. DO-41's 4.3mm); higher thermal mass but incompatible lead spacing | Choose for systems requiring higher single-pulse energy absorption (e.g., utility meter main AC input) where board real estate allows larger case |
Compared with SMAJ180CA and 1.5KE180CA, the P4KE180C offers drop-in compatibility with legacy DO-41 through-hole designs, lower profile for height-constrained enclosures, and direct AEC-Q101 qualification path via P4KE180CH - making it optimal for cost-sensitive automotive and industrial replacements where layout change is prohibited.

FAQ
What is the polarity configuration of P4KE180C?
The P4KE180C is a bidirectional TVS diode with no cathode marking - both terminals are functionally identical. It clamps transients symmetrically above ±162V, eliminating need for orientation verification during placement. This design simplifies PCB layout and supports AC-coupled or floating DC applications where polarity reversal is possible. The P4KE180C achieves this using a back-to-back Zener junction structure housed in a DO-41 package.
Does P4KE180C meet AEC-Q101 qualification?
The base P4KE180C is not AEC-Q101 qualified; however, the P4KE180CH variant - identical electrically and mechanically but manufactured under automotive-grade process controls and tested per AEC-Q101 stress conditions - is certified. For automotive under-hood applications such as headlamp drivers or body control modules, specify P4KE180CH to ensure qualification. The P4KE180C remains suitable for industrial and telecom applications where AEC-Q101 is not mandated.
What is the maximum clamping voltage of P4KE180C under standard surge conditions?
The P4KE180C clamps to a maximum of 258V when subjected to a 10/1000μs surge waveform with peak current of 1.6A. This value is measured at TA = 25°C and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events. At elevated temperatures, clamping voltage increases slightly due to the 0.108%/°C temperature coefficient of VBR - a factor critical for thermal design in enclosed enclosures.
Can P4KE180C replace P4KE180A in existing designs?
Yes, the P4KE180C can replace P4KE180A in most applications because both share identical VWM (146V), VBR range (162–198V), VC (258V), and package (DO-41). The "C" suffix denotes bidirectional configuration, while "A" indicates tighter VBR tolerance (±5% vs. ±10% for non-A parts); however, P4KE180A itself is also bidirectional per TSC documentation. Verify that the original design relies on bidirectional clamping - if unidirectional behavior was intended, P4KE180C remains functionally appropriate but requires no polarity alignment.
What is the reverse leakage current specification for P4KE180C at its working voltage?
The P4KE180C exhibits ≤1μA reverse leakage current at its maximum working stand-off voltage of 146V, measured at TA = 25°C. This ultra-low leakage preserves power efficiency in battery-backed or low-quiescent-current systems and prevents false triggering in high-impedance sensing nodes. Leakage remains below 5μA up to 175°C junction temperature, supporting reliable operation in thermally demanding environments like engine control units or outdoor telecom cabinets.
