Product details
Overview
P4KE220CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 209 V to 231 V breakdown voltage (VBR), 185 V standoff voltage (VWM), 328 V maximum clamping voltage (VC) at 1.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE220CA-E3/54 datasheet, P4KE220CA-E3/54 pinout, P4KE220CA-E3/54 application, or P4KE220CA-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade transient protection design.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its 10/1000 μs waveform response enables effective suppression of ESD, lightning-induced surges, and inductive switching transients without polarity sensitivity.
Thermal performance is defined by 66 °C/W junction-to-lead resistance and 100 °C/W junction-to-ambient (LLead = 10 mm), supporting operation from –55 °C to +175 °C. The 1.5 W steady-state power dissipation and 400 W peak pulse capability are derated linearly above 25 °C ambient per Fig. 2 and Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1.0 mA test current - defines reliable avalanche initiation threshold under reverse bias in both directions |
| VWM | 185 V - maximum continuous working voltage before leakage exceeds 1.0 μA, setting safe operating margin below clamping |
| VC @ IPPM | 328 V at 1.2 A peak pulse current - clamped voltage during 10/1000 μs transient, directly limiting downstream IC stress |
| PPPM | 400 W - peak transient energy handling capacity with 0.01 % duty cycle, enabling repetitive surge suppression in industrial controls |
| TJ max. | +175 °C - maximum junction temperature allowing sustained operation in under-hood automotive or high-ambient industrial environments |
| RθJL | 66 °C/W - low thermal resistance from junction to lead supports PCB-level heat sinking via copper pour or thermal vias |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with matte tin-plated leads; RoHS-compliant, AEC-Q101 qualified (E3 suffix denotes JESD 201 Class 1A whisker test compliance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (unmarked) | Bidirectional avalanche junction terminals | No polarity marking required; symmetric conduction enables placement without orientation check in AC-coupled or floating lines |
| Lead 1 / Lead 2 | Current path through passivated chip | Leads serve as both mechanical attachment and thermal conduction path; 275 °C solder dip tolerance supports wave/reflow reflow |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, low-leakage avalanche behavior over lifetime and temperature, critical for long-term reliability in automotive modules |
| 400 W peak pulse power (10/1000 μs) | Handles common surge standards including ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 without degradation |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, ADAS sensor interfaces, and infotainment power rails |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures, satisfying safety requirements for industrial and transportation equipment |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive analog front-ends |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤328 V while maintaining <1.0 μA leakage at 185 V, preserving signal integrity and preventing latch-up in 5 V/12 V sensor interfaces. |
Use Scenario: Safeguarding digital input/output channels in programmable logic controllers against inductive kickback from solenoids and contactors. IC Role / Device Role / Timing Role: Primary surge suppression device mounted at connector entry point on DIN-rail mounted I/O modules. Use Value: Withstands 400 W pulses at 0.01 % duty cycle and operates up to +175 °C, enabling robust field deployment in factory automation cabinets. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from lightning-induced surges on outdoor-facing telecom ports. IC Role / Device Role / Timing Role: First-stage transient suppressor on RJ-45 or F-type coaxial input paths before isolation transformers or TVS arrays. Use Value: Symmetric clamping ensures equal protection for positive/negative transients on balanced lines, meeting ITU-T K.21 basic protection level. |
Use Scenario: Secondary-side overvoltage clamp on DC output rails of wall-mounted AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Fail-safe shunt device that activates only during abnormal overvoltage (e.g., regulator failure), not during normal ripple. Use Value: 185 V VWM provides margin above 120 VRMS × √2 ≈ 170 V peak, ensuring no conduction during nominal operation while clamping fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | DO-214AA package, 200 W peak power, lower clamping voltage (300 V), higher capacitance (~100 pF) | Better suited for high-speed data lines where lower VC matters more than power handling | Select when board space allows SMC/SMB footprint and clamping voltage margin is prioritized over pulse energy capacity |
| 1.5KE220CA | DO-201AD package, 1500 W peak power, same VBR/VWM, higher IPPM (6.8 A) | Designed for primary-side AC line protection and higher-energy surge events (IEC 61000-4-5 Level 4) | Choose when system-level surge testing requires >400 W capability and larger PCB real estate is available |
Compared with P4KE220CA-E3/54, SMBJ220CA offers tighter clamping but reduced energy handling and higher parasitic capacitance, while 1.5KE220CA delivers 3.75× higher peak power in a larger package - selection depends on whether board area, clamping precision, or surge energy absorption is the dominant constraint.

FAQ
What is the breakdown voltage range for P4KE220CA-E3/54?
The P4KE220CA-E3/54 has a guaranteed breakdown voltage (VBR) range of 209 V to 231 V at 1.0 mA test current, measured in both directions due to its bidirectional construction. This specification ensures consistent avalanche initiation across polarity and is validated per ANSI/IEEE C62.35 standards.
Is P4KE220CA-E3/54 suitable for automotive applications?
Yes, P4KE220CA-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive systems. Its DO-41 package, glass-passivated junction, and 400 W pulse rating align with ISO 7637-2 and ISO 16750-2 transient immunity requirements.
What does the "CA" suffix indicate in P4KE220CA-E3/54?
The "CA" suffix in P4KE220CA-E3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., P4KE220A), it has no cathode band marking and is used where polarity is undefined or alternating.
How does the clamping voltage of P4KE220CA-E3/54 compare to its standoff voltage?
P4KE220CA-E3/54 has a standoff voltage (VWM) of 185 V and a maximum clamping voltage (VC) of 328 V at 1.2 A peak pulse current. This 143 V headroom ensures reliable non-conduction during normal operation while limiting transient overvoltage to a predictable, safe level for downstream circuitry.
What packaging and compliance certifications apply to P4KE220CA-E3/54?
P4KE220CA-E3/54 uses a DO-41 (DO-204AL) package with matte tin-plated leads, UL 94 V-0 compliant epoxy molding, and meets RoHS Directive 2011/65/EU. The "E3" suffix confirms JESD 201 Class 1A whisker resistance and commercial-grade AEC-Q101 qualification per Vishay document 88365.
