Product details
Overview
P4KE30CA-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 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 400 W peak pulse power (10/1000 μs), and clamps to ≤41.4 V at 9.7 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE30CA-E3/54 datasheet, P4KE30CA-E3/54 pinout, P4KE30CA-E3/54 application, or P4KE30CA-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 environments, and verified 175 °C maximum junction temperature operation.
Technical Context
The P4KE30CA-E3/54 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 suppression of lightning-induced surges and inductive switching spikes without polarity sensitivity.
It exhibits low incremental surge resistance and fast response time (<1 ns), with thermal resistance RθJL = 66 °C/W enabling reliable power dissipation under transient conditions. The device is rated for 1.5 W steady-state power dissipation at TL = 75 °C and supports repetitive surge duty cycles up to 0.01 %.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA test current - defines precise avalanche onset threshold for bidirectional clamping |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 41.4 V at 9.7 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, validated per Fig. 1 |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for layout-dependent thermal management |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and J-STD-002 solderability standard. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | No functional distinction between leads - either end connects to protected line or ground; no orientation required during placement |
| Lead 1 / Lead 2 | Current path for transient conduction | Both leads conduct equally during positive or negative overvoltage events; solder joint design must support 40 A surge (IFSM) in unidirectional mode if used asymmetrically |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when combined with appropriate series impedance |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio suppressors |
| Solder dip tolerance (275 °C, 10 s) | Ensures robustness during wave soldering processes without parametric shift or bond degradation |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Use Scenario: Protecting Ethernet PHY interfaces and DSL line drivers from lightning-induced longitudinal surges on twisted-pair telecom lines. IC Role / Device Role / Timing Role: Bidirectional TVS placed differential-mode across line pairs, referenced to isolated ground plane. Use Value: Symmetrical clamping ensures equal protection for positive and negative transients, critical for full-duplex communication integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Surface-mount SMB package (vs. through-hole DO-41); same VBR, lower RθJA (50 °C/W), 600 W PPPM | Preferred for space-constrained PCBs and automated SMT assembly; not suitable for manual repair or high-vibration mechanical retention | Select SMBJ30CA when board area is limited and reflow compatibility is required; verify pad thermal relief for 400 W surge energy dissipation. |
| 1.5KE30CA | Higher PPPM = 1500 W, larger DO-201AE package, same VBR and bidirectional configuration | Used where higher surge margin is mandated (e.g., outdoor telecom cabinets, utility metering), with greater mechanical robustness | Choose 1.5KE30CA for applications requiring >400 W headroom or extended lifetime under frequent surge exposure; requires larger PCB footprint and lead spacing. |
Compared with SMBJ30CA and 1.5KE30CA, the P4KE30CA-E3/54 offers optimal balance of proven DO-41 mechanical reliability, AEC-Q101 qualification, and cost-effective through-hole manufacturability - making it preferred for automotive and industrial control modules where serviceability and vibration resistance are prioritized over miniaturization.

FAQ
What is the polarity configuration of the P4KE30CA-E3/54?
The P4KE30CA-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics - neither lead is designated anode or cathode. This eliminates orientation constraints during PCB placement and ensures identical clamping behavior for positive and negative transients. The "CA" suffix explicitly denotes bidirectional functionality per Vishay's naming convention.
Does the P4KE30CA-E3/54 meet automotive qualification standards?
Yes, the P4KE30CA-E3/54 is AEC-Q101 qualified, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and humidity bias HAST. This qualification validates its use in automotive powertrain, body electronics, and ADAS subsystems where reliability under thermal and mechanical stress is mandatory.
What is the maximum clamping voltage of the P4KE30CA-E3/54 under surge conditions?
The P4KE30CA-E3/54 clamps to a maximum of 41.4 V at its rated peak pulse current of 9.7 A (10/1000 μs waveform). This value is measured per Figure 1 in the Vishay datasheet 88365 and represents the upper limit of voltage imposed on protected circuitry during standardized surge events.
Can the P4KE30CA-E3/54 be used in AC line protection applications?
The P4KE30CA-E3/54 is not rated for direct AC mains protection due to its 25.6 V stand-off voltage (VWM) and lack of UL/IEC 61643-11 certification for AC line-rated suppressors. It is intended for low-voltage DC signal/power rail protection - such as 12 V/24 V automotive buses or 3.3 V/5 V data lines - where VWM exceeds nominal system voltage by ≥20 %.
What is the thermal resistance specification for the P4KE30CA-E3/54?
The P4KE30CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with lead length L = 10 mm. This parameter governs heat transfer from the silicon die to the PCB copper pour or heatsink via the leads, and must be considered when designing for repeated surge duty cycles or elevated ambient temperatures.
