Product details
Overview
P6KE200CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 200 V standoff voltage (VWM), 220–242 V breakdown range (VBR), 600 W peak pulse power (10/1000 μs), and clamps to ≤274 V at 2.2 A peak pulse current. It is used in automotive sensor interfaces and industrial I/O modules to suppress ESD and inductive switching transients.
For engineers reviewing the P6KE200CA-E3/73 datasheet, P6KE200CA-E3/73 pinout, P6KE200CA-E3/73 application, or P6KE200CA-E3/73 equivalent, this page delivers verified electrical specs, DO-15 package details, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-qualified alternatives - all grounded in Vishay's official Document #88369 (Rev. 27-Sep-2021).
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), then avalanches rapidly (<1 ns response) when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping in both polarities, critical for AC-coupled or floating signal paths.
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, with power derating linear from 5.0 W at TL = 75 °C to zero at TJ = 175 °C. The glass-passivated junction and DO-15 package support reliable operation across -55 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; sets operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 220–242 V at IT = 1 mA - Confirmed avalanche onset range; defines minimum transient level that triggers conduction. |
| VC (Clamping Voltage) | ≤274 V at IPPM = 2.2 A (10/1000 μs) - Maximum voltage seen by protected circuit during worst-case surge; determines safe IC withstand margin. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per transient event; validated for 0.01 % duty cycle repetition. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Ensures negligible standby power loss and no signal distortion in high-impedance circuits. |
| TJ max. | +175 °C - Enables use in under-hood automotive or high-temperature industrial environments without thermal shutdown. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking on bidirectional variants like P6KE200CA-E3/73.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | No functional distinction - either lead serves as input/output; clamping occurs identically for ±polarity transients. |
| Lead 1 / Lead 2 | Current path terminals | Direct connection to PCB traces; requires ≥0.375″ (9.5 mm) lead length for rated PD = 5.0 W at TL = 75 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and low leakage over lifetime; resists moisture ingress and electrochemical degradation. |
| 600 W peak pulse rating (10/1000 μs) | Handles common automotive load-dump and ISO 7637-2 Pulse 5a surges without degradation. |
| AEC-Q101 qualification | Validates suitability for automotive ECUs, body control modules, and ADAS sensor interfaces requiring zero-failure field reliability. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures; required for industrial safety certifications (e.g., IEC 62368-1). |
| Low clamping ratio (VC/VBR ≈ 1.24) | Minimizes overvoltage stress on protected ICs - e.g., keeps 3.3 V or 5 V logic within safe absolute maximum ratings. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and Hall-effect sensors from battery dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between signal line and ground, clamping transients before they reach the IC's ESD protection diodes. Use Value: Prevents latch-up or permanent gate oxide damage in 5 V tolerant transceivers during 12 V system load-dump events (ISO 7637-2). |
Use Scenario: Safeguarding 4–20 mA current-loop inputs against wiring faults and lightning-induced surges in factory-floor I/O modules. IC Role / Device Role / Timing Role: Bidirectional clamp across differential input pins, absorbing common-mode transients up to ±1 kV. Use Value: Maintains analog accuracy by limiting input voltage excursion to <274 V, avoiding ADC saturation or op-amp rail-to-rail clipping. |
| Consumer Power Adapter Output | Telecom Line Card Protection |
Use Scenario: Secondary-side overvoltage suppression on 19 V laptop adapter outputs exposed to open-load or feedback failure. IC Role / Device Role / Timing Role: Parallel-connected TVS across output capacitor, triggered only during fault conditions exceeding 220 V. Use Value: Limits output to ≤274 V, preventing catastrophic failure of downstream USB-PD controllers or buck converters. |
Use Scenario: Primary protection for Ethernet PHYs and DSL line drivers against induced surges on RJ-45 ports in central office equipment. IC Role / Device Role / Timing Role: First-stage clamp on each twisted pair, coordinated with gas discharge tube (GDT) upstream for multi-level protection. Use Value: Clamps fast-rising transients (<1 ns) before GDT fires, reducing let-through energy to <10 mJ at the IC interface. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W rating retained. | Requires PCB re-layout for SMT assembly; better suited for space-constrained designs with automated placement. | Select when board real estate is limited and reflow soldering is available; not drop-in for through-hole DO-15 footprints. |
| P6KE200AHE3/73 | Unidirectional variant with identical VWM/VBR/VC, same DO-15 package, and AEC-Q101 qualification. | Only protects against negative transients unless paired with another diode; lacks inherent AC-symmetry. | Choose only for DC-biased rails where polarity is fixed and cost-per-unit is prioritized over design simplicity. |

The P6KE200CA-E3/73 clamps to a maximum of 274 V when subjected to its specified peak pulse current of 2.2 A (10/1000 μs waveform). This value is measured per Figure 1 in Vishay Document #88369 and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping voltage remains consistent across both polarities due to the device's bidirectional construction.
Is P6KE200CA-E3/73 suitable for automotive applications?
Yes, P6KE200CA-E3/73 is AEC-Q101 qualified per Vishay's documentation, confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. Its 175 °C maximum junction temperature and DO-15 package robustness make it appropriate for under-hood and body-control module applications where transient immunity and long-term reliability are mandatory.
How does the bidirectional nature of P6KE200CA-E3/73 affect its usage compared to unidirectional TVS diodes?
The bidirectional structure of P6KE200CA-E3/73 enables symmetrical clamping for both positive and negative transients without requiring external polarity configuration. Unlike unidirectional types such as P6KE200AHE3/73, it eliminates the need for dual-diode arrangements or careful orientation during assembly - simplifying layout and improving protection coverage for AC-coupled or floating signal paths in applications like telecom line cards or sensor bridges.
