Product details
Overview
P4KE16CA-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 400 W peak pulse power (10/1000 μs), 16 V breakdown voltage (VBR min/max = 15.2–16.8 V at 1.0 mA), 13.6 V stand-off voltage (VWM), and clamps to ≤22.5 V at 17.8 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE16CA-E3/54 datasheet, P4KE16CA-E3/54 pinout, P4KE16CA-E3/54 application, or P4KE16CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and compliance with 10/1000 μs surge waveform standards.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling robust transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for repeatable clamping performance under repetitive surges.
The P4KE16CA-E3/54 is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; its 1.5 W steady-state power dissipation (PD) and 66 °C/W junction-to-lead thermal resistance support reliable operation in constrained PCB layouts with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA - defines precise clamping onset threshold in both directions |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤22.5 V at 17.8 A - peak clamped voltage during 10/1000 μs transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per single 10/1000 μs waveform, duty cycle ≤0.01 % |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJL | 66 °C/W - quantifies thermal path efficiency from junction to lead, guiding board-level thermal design |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics per stress-test requirements |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are electrically symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends function identically; connects across protected line and ground (or rail-to-rail) without orientation dependency |
| Lead 1 / Lead 2 | Thermal and electrical interface | Provides primary heat dissipation path (RθJL = 66 °C/W) and low-inductance surge current return |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures ±5 % VBR tolerance and long-term stability under thermal cycling and humidity |
| 400 W 10/1000 μs pulse rating | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes let-through energy to sensitive downstream ICs such as CAN transceivers or ADC front-ends |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS sensor interfaces |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and automotive enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | DO-214AA package (larger footprint), 600 W PPPM, same VBR range and bidirectional configuration | Better suited for higher-energy surges; requires PCB area increase and different thermal layout | Select SMBJ16CA when system-level surge testing exceeds IEC 61000-4-5 Level 4 or when higher IPPM margin is required |
| 1.5KE16CA | DO-201AE package, 1500 W PPPM, identical VBR/VWM specs but higher clamping voltage (VC = 25.6 V @ 58.3 A) | Used where higher pulse energy absorption is prioritized over low clamping voltage | Choose 1.5KE16CA for legacy designs requiring drop-in replacement with higher surge headroom, accepting +3.1 V higher clamping |
Compared with SMBJ16CA and 1.5KE16CA, the P4KE16CA-E3/54 offers optimal balance of compact DO-41 footprint, AEC-Q101 qualification, and tight 22.5 V clamping - making it preferred for space-constrained automotive and industrial modules where thermal management and reliability certification are critical.

FAQ
What does the "CA" suffix indicate in P4KE16CA-E3/54?
The "CA" suffix denotes that the P4KE16CA-E3/54 is a bidirectional Transient Voltage Suppressor, meaning it provides symmetrical clamping in both polarities - unlike unidirectional variants (e.g., P4KE16A) which require correct anode/cathode orientation. This makes the P4KE16CA-E3/54 ideal for AC-coupled or polarity-agnostic signal lines where transient direction is unpredictable.
Is P4KE16CA-E3/54 qualified for automotive applications?
Yes, the P4KE16CA-E3/54 is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. The qualification covers stress tests such as high-temperature reverse bias, temperature cycling, and highly accelerated life testing - all performed per the P4KE16CA-E3/54's published specifications and construction.
What is the maximum clamping voltage of P4KE16CA-E3/54 under surge conditions?
The P4KE16CA-E3/54 clamps to a maximum of 22.5 V at its rated peak pulse current of 17.8 A (10/1000 μs waveform). This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit protection design - ensuring connected ICs like microcontrollers or transceivers remain within safe absolute maximum ratings during transient events.
Can P4KE16CA-E3/54 be used in place of unidirectional P4KE16A?
No - the P4KE16CA-E3/54 is bidirectional and has no polarity marking, while P4KE16A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: P4KE16CA-E3/54 works only where symmetrical clamping is needed (e.g., differential lines), whereas P4KE16A must be oriented correctly for DC-biased rails. Using P4KE16CA-E3/54 in a unidirectional design may result in unintended forward conduction.
What packaging format is supplied for P4KE16CA-E3/54?
The P4KE16CA-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 5500 pieces per reel (ordering code /54). The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance - suitable for standard reflow and wave soldering processes per J-STD-002 and JESD 22-B102.
