Product details
Overview
P4KE220C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 220V nominal standoff voltage, 242V maximum breakdown voltage at 1mA test current, 175V working voltage, 1.2A peak pulse current (10/1000μs), and clamps transients to ≤344V - deployed in automotive lighting control modules and industrial PLC I/O protection.
For engineers reviewing the P4KE220C datasheet, P4KE220C pinout, P4KE220C application, or P4KE220C equivalent, key selection criteria include its bidirectional polarity marking, DO-41 package compatibility with through-hole PCB layouts, low leakage (<1μA at 175V), and AEC-Q101 qualification for automotive-grade reliability under repetitive EFT and lightning surge stress.
Technical Context
The P4KE220C operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - both anodes tied internally, cathodes exposed at each end - enabling identical VBR (198–242V) and VC (≤344V) performance in either polarity. Its 400W peak pulse power rating is defined per 10/1000μs waveform per ANSI/IEEE C62.35, with junction temperature range from –55°C to +175°C.
It exhibits fast transient response (≤5.0ns rise time from 0V to VBR), low dynamic impedance during clamping, and a temperature coefficient of VBR = 0.108%/°C - critical for stable overvoltage protection across wide ambient and self-heating conditions in unregulated DC bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 175 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for system DC rail voltage |
| VBR (min/max) | 198 / 242 V @ 1 mA - guaranteed avalanche onset window; ensures reliable triggering above normal operating voltage |
| VC @ IPPM | ≤344 V @ 1.2 A - clamped voltage during 10/1000μs surge; defines worst-case stress on downstream ICs |
| PPK | 400 W - peak pulse power handling per single 10/1000μs event; supports IEC 61000-4-5 Level 3/4 surges |
| ID @ VWM | <1 μA - ultra-low reverse leakage at rated standoff; minimizes standby power loss and thermal drift |
| TJ max | +175 °C - maximum junction temperature; enables operation in engine bay or industrial enclosures without derating |
| Package | DO-204AL (DO-41) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding compound |
Pinout & Package
DO-204AL (DO-41) axial-leaded package with cathode band marking omitted for bidirectional configuration; terminals are non-polarized and interchangeable - no functional distinction between anode/cathode ends.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode 1 | Bidirectional terminal A | Either end serves as clamping node; symmetric conduction allows flexible placement in AC or floating DC lines |
| Anode 2 / Cathode 2 | Bidirectional terminal B | Electrically identical to Terminal A; no polarity sensitivity - installed without orientation check |
Key Features

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 SMAJ220CA | Same DO-214AC (SMA) package; 220V VWM, 356V VC @ 1.13A; 400W rating; faster 1ps unidirectional response but bidirectional spec matches P4KE220C | Surface-mount only; requires rework of PCB layout; better high-frequency ESD immunity due to lower junction capacitance (150pF vs 220pF) | Select when board space is constrained and SMT assembly is preferred over through-hole. |
| ON Semiconductor 1.5KE220CA | Higher 1500W rating; same DO-204AL package; 220V VWM, 344V VC @ 4.35A; wider VBR tolerance (198–242V same); higher TJ max (+175°C) | Over-specified for 400W use cases; larger thermal mass delays response slightly; suited for repeated surge environments like wind turbine pitch control | Select when system must survive >5000 surge events or operate continuously at elevated ambient temperatures (>105°C). |
Compared with SMAJ220CA and 1.5KE220CA, the P4KE220C offers optimal balance of cost, proven automotive qualification (AEC-Q101), and axial-leaded manufacturability - making it ideal for legacy through-hole designs where footprint and reliability outweigh raw power rating.

FAQ
What is the polarity configuration of P4KE220C?
The P4KE220C is a bidirectional TVS diode with symmetrical clamping characteristics in both directions. It has no cathode band marking and both terminals are functionally identical - enabling installation without orientation concern in AC-coupled or floating DC circuits. This differs from unidirectional variants like P4KE220A, which require correct polarity alignment.
Does P4KE220C meet AEC-Q101 requirements?
Yes, the P4KE220C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet (Version N2104). It undergoes stress testing including temperature cycling, high-temperature operating life, and mechanical shock per JESD22 standards - validating its suitability for automotive underhood and chassis-mounted applications.
What is the maximum clamping voltage of P4KE220C under surge conditions?
The maximum clamping voltage (VC) of P4KE220C is 344 V when subjected to its rated peak pulse current of 1.2 A under the standard 10/1000μs waveform. This value is measured at the device terminals and represents the worst-case voltage imposed on protected circuitry during transient events.
Can P4KE220C be used in place of P4KE220A?
No - P4KE220C is bidirectional while P4KE220A is unidirectional. Substituting them without circuit review risks failure: P4KE220A conducts forward current below VBR and blocks reverse voltage up to VWM, whereas P4KE220C clamps in both directions. Use P4KE220C only where bidirectional protection is explicitly required.
What packaging options are available for P4KE220C?
P4KE220C is supplied in DO-204AL (DO-41) axial-leaded package, available in tape-and-reel (5,000 pcs) and ammo box (3,000 pcs) formats. The part marking includes voltage code "220" and suffix "C" denoting bidirectional configuration; lead finish is pure tin per J-STD-002 for reliable solderability.
