Product details
Overview
P4KE200CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on AC-coupled or differential signal lines. It features 200 V standoff voltage (VWM), 228–252 V breakdown range (VBR), 400 W peak pulse power (10/1000 μs), and clamps to ≤328 V at 1.5 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P4KE200CA-E3/54 datasheet, P4KE200CA-E3/54 pinout, P4KE200CA-E3/54 application, or P4KE200CA-E3/54 equivalent, this page delivers verified electrical specs, DO-41 terminal mapping, bidirectional clamping behavior, AEC-Q101 qualification status, and direct alternatives for ESD/lightning surge protection in 24 V and 48 V systems.
Technical Context
This device operates as a symmetrical avalanche diode with identical forward and reverse clamping characteristics - enabling protection of bidirectional data lines (e.g., RS-485, CAN FD, analog sensor bridges) without polarity concerns. Its glass-passivated junction ensures stable VBR over temperature and long-term reliability under repetitive surge stress.
Rated for 175 °C maximum junction temperature and 100 °C/W thermal resistance (junction-to-ambient), the P4KE200CA-E3/54 sustains transient energy dissipation without thermal runaway when mounted on standard PCB copper. The 1.5 W steady-state power rating supports continuous leakage management in high-impedance monitoring circuits.
Key Specifications

IC Role / Device Role / Timing Role: Line-to-line and line-to-ground TVS on A/B bus terminals, absorbing common-mode and differential-mode energy without affecting DC bias. Use Value: Maintains bus integrity during 4 kV EFT (IEC 61000-4-4) and 1 kV surge (IEC 61000-4-5) events due to low clamping ratio (VC/VWM = 1.64). |
| Telecom DSL Line Card | Medical Patient Monitor Analog Inputs |
Use Scenario: Front-end protection of ADSL/VDSL line drivers and receivers subjected to induced surges from nearby power lines or lightning coupling. IC Role / Device Role / Timing Role: Primary surge clamp on tip/ring pairs, coordinated with gas discharge tubes (GDTs) for staged protection architecture. Use Value: Fast response (<1 ns) and low capacitance (<100 pF) prevent signal distortion on broadband DSL signals up to 30 MHz. |
Use Scenario: Isolation barrier protection for ECG/SpO₂ analog front-ends where patient-connected inputs must survive defibrillation pulses and ESD events. IC Role / Device Role / Timing Role: Secondary protection stage after optocoupler or transformer isolation, limiting residual transients to <100 V on isolated side. Use Value: AEC-Q101 qualification correlates with long-term stability required for Class II medical devices; leakage <1 μA avoids baseline drift in precision amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | DO-214AA package, 600 W PPPM, lower clamping (VC = 324 V @ 1.7 A), higher capacitance (~150 pF) | Better suited for space-constrained PCBs requiring surface-mount assembly; less optimal for high-frequency analog lines due to higher CJ | Select SMBJ200CA when automated SMT placement is mandatory and board real estate is limited; verify layout thermal relief for 600 W surge handling. |
| 1.5KE200CA | DO-201AD package, 1500 W PPPM, higher VC (360 V @ 4.2 A), same VWM/VBR range, higher IFSM (125 A) | Designed for higher-energy threats (e.g., IEC 61000-4-5 Level 4); requires larger pad area and longer trace clearance | Choose 1.5KE200CA when system-level testing requires >400 W surge margin or legacy through-hole compatibility with larger footprint is acceptable. |
