Product details
Overview
P4KE200CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features 400 W peak pulse power (10/1000 μs), 171 V stand-off voltage (VWM), 200–210 V breakdown voltage (VBR), and clamps to ≤274 V at 1.5 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P4KE200CAHE3/54 datasheet, P4KE200CAHE3/54 pinout, P4KE200CAHE3/54 application, or P4KE200CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, and verified 175 °C junction temperature rating for under-hood and motor-control environments.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche breakdown in both polarities, enabling use without polarity awareness in AC-coupled or floating signal paths. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping across repetitive transients.
The P4KE200CAHE3/54 delivers defined clamping performance under standardized 10/1000 μs waveform conditions, with thermal derating governed by RθJA = 100 °C/W and RθJL = 66 °C/W. Its AEC-Q101 qualification confirms suitability for automotive applications requiring robustness against thermal cycling and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC/AC working margin. |
| VBR min/max | 200 V / 210 V at 1 mA - guaranteed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤274 V at 1.5 A - clamped voltage under full-rated 400 W surge; determines protected circuit's maximum stress level. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; validates immunity to common ISO 7637-2 and IEC 61000-4-5 threats. |
| TJ max | +175 °C - maximum junction temperature; supports operation in engine bay, motor drives, and high-ambient industrial enclosures. |
| ID @ VWM | ≤1.0 μA - reverse leakage at stand-off voltage; minimizes standby power loss in battery-powered systems. |
| Package | DO-41 (DO-204AL) - industry-standard axial leaded package with UL 94 V-0 molded epoxy body and matte tin-plated leads. |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, cylindrical epoxy-molded body, 2.0–2.7 mm diameter, 5.2 mm minimum length, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Bidirectional construction means no cathode marking; terminals are non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends function identically; conducts surge current in either direction once VBR is exceeded. |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads serve as primary heat dissipation path (RθJL = 66 °C/W); require ≥10 mm lead length for rated PD = 1.5 W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, mechanical shock, and humidity testing per JESD22 standards. |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in harsh environments. |
| 400 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-earth) surge immunity requirements without external series impedance. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, protecting downstream MOSFET gates and MCU I/O pins. |
| RoHS-compliant HE3 suffix | Meets JESD201 Class 2 whisker resistance and automotive material compliance (Vishay doc# 99912). |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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. axial DO-41); same VWM (171 V), lower PPPM (600 W), higher VC (274 V @ 2.2 A). | Requires PCB rework for SMT assembly; better suited for space-constrained designs with automated placement. | Select SMBJ200CA when board real estate is limited and thermal coupling to copper pour can support higher peak power. |
| 1.5KE200CA | Higher PPPM (1500 W), larger DO-201 package; identical VWM/VBR/VC specs but 3× higher surge current rating (5.3 A vs. 1.5 A). | Used where single-event surge energy exceeds 400 W, e.g., main AC input stages or industrial power supplies. | Choose 1.5KE200CA only if system-level testing confirms need for >400 W clamping; otherwise P4KE200CAHE3/54 offers optimal cost-size-performance balance. |
Compared with SMBJ200CA and 1.5KE200CA, the P4KE200CAHE3/54 provides AEC-Q101 qualification and DO-41 through-hole compatibility out-of-box, making it the preferred choice for automotive and legacy industrial designs where mechanical robustness and serviceability outweigh SMT density or ultra-high-power needs.

FAQ
What is the clamping voltage of P4KE200CAHE3/54 under maximum rated surge current?
The P4KE200CAHE3/54 clamps to a maximum of 274 V when subjected to its rated peak pulse current of 1.5 A (corresponding to 400 W with a 10/1000 μs waveform). This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P4KE200CAHE3/54 suitable for automotive applications?
Yes, the P4KE200CAHE3/54 carries the HE3 suffix, indicating AEC-Q101 qualification per Vishay's documentation. It meets automotive requirements for temperature cycling, mechanical shock, and humidity resistance, and is explicitly recommended for sensor unit protection and ECU power rail clamping in vehicles.
How does the bidirectional design of P4KE200CAHE3/54 affect its circuit implementation?
The bidirectional architecture of P4KE200CAHE3/54 eliminates polarity sensitivity - it functions identically regardless of orientation across a line or rail. This simplifies layout, avoids cathode-marking errors, and enables direct placement on AC-coupled signals or floating differential buses like RS-485 or CAN without additional diodes or biasing.
What is the maximum operating temperature for P4KE200CAHE3/54?
The P4KE200CAHE3/54 has a maximum junction temperature (TJ max) of +175 °C, confirmed in Vishay's Thermal Characteristics table. This allows reliable operation in under-hood automotive locations, motor drive heatsinks, and industrial enclosures where ambient temperatures exceed 105 °C, provided thermal derating per Figure 5 is observed.
Does P4KE200CAHE3/54 require a heatsink for standard 400 W surge handling?
No external heatsink is required for single-event 400 W surges, as the P4KE200CAHE3/54 relies on short-duration thermal mass of its DO-41 leads and junction. However, for repetitive surges or continuous power dissipation, derating applies: its 1.5 W steady-state power rating assumes TL = 75 °C with 10 mm lead length, per Figure 5 in the datasheet.
