Product details
Overview
P4KE62CA-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 a 62 V breakdown voltage (VBR min/max = 58.9–65.1 V), 400 W peak pulse power (10/1000 μs), and clamps to ≤85.0 V at 4.7 A peak pulse current - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE62CA-E3/54 datasheet, P4KE62CA-E3/54 pinout, P4KE62CA-E3/54 application, or P4KE62CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility with through-hole PCB layouts, AEC-Q101 qualification for automotive use, and verified 175 °C maximum junction temperature operation.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) transient voltage exceeds its breakdown threshold, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at 53.0 V stand-off).
Designed for unidirectional and bidirectional configurations, P4KE62CA-E3/54 uses symmetric avalanche characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity sensitivity. Its 66 °C/W junction-to-lead thermal resistance supports reliable power dissipation under repetitive surge conditions up to 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 58.9–65.1 V at 1.0 mA test current - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 53.0 V - maximum continuous working voltage before leakage rises above 1.0 μA |
| Peak Pulse Power PPPM | 400 W (10/1000 μs waveform) - sustains single high-energy surges common in automotive load-dump or inductive switching |
| Clamping Voltage VC | ≤85.0 V at 4.7 A IPPM - limits downstream voltage stress during full-rated surge event |
| Junction Temperature Range | –55 °C to +175 °C - enables deployment in under-hood automotive or industrial environments |
| Package | DO-41 (DO-204AL) - standard axial-leaded through-hole package with UL 94 V-0 epoxy body |
| AEC-Q101 Qualified | Yes - validated for automotive electronic systems requiring robust reliability and qualification traceability |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated axial leads; no polarity marking for bidirectional types - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as input/output - no cathode band; identical clamping behavior in both directions |
| Lead 1 / Lead 2 | Current path to PCB copper pour or heatsink | Leads conduct surge current to board-level thermal mass; RθJL = 66 °C/W enables effective heat transfer |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and <1.0 μA leakage at VWM, critical for low-power sensor interfaces |
| 400 W peak pulse rating (10/1000 μs) | Handles ISO 7637-2 Pulse 1/2a/5a surge levels without degradation in automotive ECUs and body controllers |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial control cabinets and automotive junction boxes |
| Solderable per J-STD-002/JESD 22-B102 | Compatible with standard wave and reflow soldering processes; 275 °C max solder dip for 10 s |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Surface-mount SMB package; same 64 V VBR, 600 W PPPM, lower clamping (≤104 V at 5.8 A) | Requires SMT layout; better suited for space-constrained telecom modules than through-hole industrial boards | Select when board real estate is limited and higher pulse power margin is needed |
| 1.5KE62CA | Same DO-41 package but higher 1500 W PPPM rating; VBR 58.9–65.1 V; larger case volume and higher VF | Used where legacy 1.5 kW surge standards apply (e.g., IEC 61000-4-5 Level 4) | Choose for enhanced surge margin in high-risk industrial mains-connected equipment |
Compared with SMBJ64CA and 1.5KE62CA, P4KE62CA-E3/54 offers optimal balance of proven through-hole manufacturability, AEC-Q101 qualification, and 400 W surge handling - making it ideal for cost-sensitive, high-volume automotive and industrial designs where DO-41 placement and qualification traceability are mandatory.

FAQ
What is the breakdown voltage tolerance for P4KE62CA-E3/54?
The P4KE62CA-E3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, corresponding to ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge design margins in automotive and industrial applications where P4KE62CA-E3/54 is deployed.
Is P4KE62CA-E3/54 suitable for automotive applications?
Yes, P4KE62CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction stability, and DO-41 mechanical robustness meet stringent automotive reliability requirements. P4KE62CA-E3/54 is commonly used in engine control units, body electronics, and ADAS sensor interfaces where transient immunity is critical.
Does P4KE62CA-E3/54 have polarity markings?
No, P4KE62CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., P4KE62A), the CA suffix indicates symmetrical avalanche characteristics in both directions - meaning either lead can connect to either side of the protected circuit. This eliminates orientation concerns during manual or automated assembly of P4KE62CA-E3/54 into DO-41 footprints.
What is the maximum clamping voltage of P4KE62CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE62CA-E3/54 is 85.0 V at 4.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a full-rated surge event, directly informing safe operating area calculations for protected ICs such as CAN transceivers or microcontroller GPIOs interfacing with P4KE62CA-E3/54.
How does the DO-41 package of P4KE62CA-E3/54 affect thermal performance?
The DO-41 package of P4KE62CA-E3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, enabling efficient heat conduction from the silicon die to PCB copper pours or heatsinks. When mounted with 10 mm lead length, its junction-to-ambient resistance is 100 °C/W - a key parameter for derating power dissipation above 25 °C ambient, especially in sealed enclosures where P4KE62CA-E3/54 operates near its 175 °C TJMAX.
