Product details
Overview
P4KE200CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 200V working stand-off voltage (VWM), 274V maximum clamping voltage (VC) at 1.51A peak pulse current, and 400W peak pulse power rating per 10/1000μs waveform - deployed in automotive lighting control modules to safeguard CAN transceivers against load dump and EFT events.
For engineers reviewing the P4KE200CA datasheet, P4KE200CA pinout, P4KE200CA application, or P4KE200CA equivalent, key selection criteria include bidirectional clamping symmetry, low leakage (<1μA @ 171V), DO-41 package compatibility with through-hole PCB layouts, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
The P4KE200CA operates as a silicon avalanche diode with symmetrical breakdown behavior in both polarities, enabling robust protection of balanced interfaces like RS-485 or differential sensor lines. Its 200V nominal voltage corresponds to a VBR range of 190–210V at 1mA test current, with temperature coefficient of 0.108%/°C ensuring stable clamping across -55°C to +175°C junction operation.
Clamping response is characterized by sub-nanosecond turn-on (≤5ns for bidirectional mode), low dynamic impedance, and guaranteed 274V VC at IPPM = 1.51A - validated per ANSI/IEEE C62.35 standards. The device sustains 400W non-repetitive surges without degradation when mounted on standard 5×5 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (min/max) | 190 / 210 V @ 1 mA - symmetric breakdown onset defining bidirectional protection window |
| VC @ IPPM | 274 V @ 1.51 A - peak clamped voltage during 10/1000μs surge; determines protected circuit's voltage stress limit |
| PPK | 400 W - peak pulse power handling per standardized waveform; defines single-event energy absorption capacity |
| ID @ VWM | <1 μA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |

Applications
| Automotive Lighting Control | Industrial RS-485 Networks |
|---|---|
Use Scenario: Protecting LED driver ICs and microcontrollers from load dump transients in 24V vehicle lighting systems. IC Role / Device Role: Primary overvoltage clamp placed across power input rails upstream of DC-DC converters. Use Value: Limits rail voltage to ≤274V during ISO 7637-2 Pulse 5a events, preventing latch-up or gate oxide rupture in downstream FETs and regulators. | Use Scenario: Safeguarding RS-485 transceivers in factory automation PLCs exposed to EFT bursts and ground loop surges. IC Role / Device Role: Bidirectional TVS connected between differential bus lines (A/B) and ground to shunt common-mode transients. Use Value: Maintains signal integrity by clamping fast-rising EFT pulses (IEC 61000-4-4 Level 4) without distorting data edges due to symmetrical 5ns response. |
| Smart Meter Power Input | Medical Sensor Interface |
Use Scenario: Securing AC/DC auxiliary power supply inputs in utility smart meters subjected to lightning-induced surges on distribution lines. IC Role / Device Role: First-stage protection element placed after fuse and before bridge rectifier to absorb line-to-line and line-to-ground spikes. Use Value: Withstands 400W 10/1000μs surges while maintaining <1μA leakage at 171V - preserving meter accuracy and low-power sleep modes. | Use Scenario: Shielding analog front-end amplifiers in portable patient monitors from ESD events during cable handling or probe connection. IC Role / Device Role: Low-capacitance bidirectional clamp across differential sensor inputs (e.g., ECG leads) referenced to isolated ground. Use Value: Delivers sub-5ns clamping without adding signal path capacitance that would degrade high-frequency biopotential bandwidth (>1 kHz). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Surface-mount SMB package (vs. through-hole DO-41); same 200V VWM and 274V VC rating | Requires PCB redesign for SMT assembly; better high-frequency performance due to lower parasitic inductance | Select when board space is constrained and automated reflow is preferred over wave soldering |
| 1.5KE200CA | Higher 1500W peak power rating; larger DO-201AE package; 287V VC at 5.2A IPPM | Over-specified for 400W-level threats; suited for primary AC input protection where higher energy absorption is mandated | Select only if system-level surge testing exceeds IEC 61000-4-5 Level 3 (1kV/2kA) requirements |
Compared with SMBJ200CA and 1.5KE200CA, the P4KE200CA offers optimal balance of proven automotive reliability (AEC-Q101), through-hole manufacturability, and precise 400W energy handling - making it ideal for cost-sensitive, medium-energy protection in lighting and industrial control nodes.

FAQ
What does the 'CA' suffix indicate in P4KE200CA?
The 'CA' suffix in P4KE200CA denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse polarities. Unlike unidirectional variants (e.g., P4KE200A), the P4KE200CA has identical breakdown and clamping characteristics regardless of voltage polarity, eliminating orientation constraints during PCB placement and simplifying design for AC-coupled or differential signal paths.
Is P4KE200CA AEC-Q101 qualified?
Yes, the P4KE200CA is AEC-Q101 qualified when ordered with the 'H' suffix (e.g., P4KE200CAH). Per Taiwan Semiconductor's ordering information, the 'H' code indicates full AEC-Q101 stress testing including HTGB, HTRB, and temperature cycling - confirming suitability for automotive under-hood applications. Standard P4KE200CA parts may not carry this qualification unless explicitly marked with 'H' in the ordering code.
What is the maximum clamping voltage of P4KE200CA and at what current is it specified?
The maximum clamping voltage (VC) of the P4KE200CA is 274 V, measured at a peak pulse current (IPPM) of 1.51 A under the standardized 10/1000μs waveform. This value represents the upper limit of voltage seen by protected circuitry during a worst-case surge event and is guaranteed across the full operating temperature range of –55°C to +175°C.
How does P4KE200CA differ from P4KE200A?
The P4KE200CA is bidirectional, whereas P4KE200A is unidirectional. Their electrical parameters differ accordingly: P4KE200CA has symmetric VBR (190–210 V) and VC (274 V) in both directions, while P4KE200A specifies forward VF (6.5 V) and lacks reverse breakdown definition. Additionally, P4KE200CA omits the cathode band marking required for P4KE200A, reflecting its polarity-agnostic construction.
Can P4KE200CA be used in place of P4KE200?
No - P4KE200 is unidirectional with a cathode band and forward voltage specification (VF = 6.5 V), while P4KE200CA is bidirectional with no polarity marking and symmetrical clamping. Substituting P4KE200CA for P4KE200 would eliminate intended forward conduction behavior in DC-biased circuits and may compromise protection in applications relying on unidirectional clamping architecture, such as certain power supply input stages.
