Product details
Overview
P4KE16-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and ESD events on power rails and signal lines. It features 16 V breakdown voltage (VBR min/max: 15.2–16.8 V), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P4KE16-E3/54 datasheet, P4KE16-E3/54 pinout, P4KE16-E3/54 application, or P4KE16-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, IPPM capability under system-level surge profiles, thermal derating above 25 °C, and compatibility with DO-41 footprint and lead-soldering requirements per J-STD-002.
Technical Context
The P4KE16-E3/54 operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages. Its unidirectional polarity uses a cathode band marking, and it conducts only in reverse bias above VBR, clamping to ≤22.5 V at 17.8 A while limiting forward voltage to ≤3.5 V at 25 A.
Thermal performance is defined by RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). It supports continuous power dissipation of 1.5 W on infinite heatsink at TL = 75 °C and withstands 40 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines minimum and maximum voltage at which avalanche conduction begins reliably at 1.0 mA test current |
| VWM | 13.6 V - maximum DC or continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.5 V at 17.8 A - clamped voltage during 10/1000 µs surge; determines protection margin for downstream 15 V-rated components |
| PPPM | 400 W - peak pulse power handling capacity under standardized 10/1000 µs waveform, duty cycle ≤0.01 % |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush or fault-current scenarios |
| TJ max. | +175 °C - maximum junction temperature, enabling operation in under-hood automotive or industrial ambient up to +125 °C with proper derating |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 class 1A whisker resistance. Overall length: 25.4 mm min., diameter: 2.0–2.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); carries full surge current during forward conduction events |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates reverse-biased avalanche at ≥15.2 V to clamp transients |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, low-leakage avalanche behavior over temperature and lifetime, with <1.0 μA ID at VWM |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity without external series impedance |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive powertrain and body electronics applications requiring reliability under thermal cycling and vibration |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving clamping precision for sensitive 15 V logic interfaces |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in enclosed industrial enclosures and consumer power supplies |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load-dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, acting as last-line voltage clamp before LDO or MCU power pins. Use Value: Clamps 12 V rail to ≤22.5 V during 400 W surges, preserving 15 V absolute maximum rating of automotive-grade microcontrollers. | Use Scenario: Shielding analog output lines of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at connector entry point, shunting transients before op-amp or ADC input stage. Use Value: Sub-1 ns response ensures clamping occurs before sensor front-end damage; 13.6 V VWM avoids interference with 10 V full-scale analog signals. |
| Consumer AC-DC Adapter Output | Telecom DSL Line Interface |
Use Scenario: Secondary-side overvoltage suppression in offline SMPS delivering regulated 12 V to USB peripherals. IC Role / Device Role / Timing Role: Standoff-rated TVS across output capacitor, absorbing transformer leakage spikes and rectifier reverse recovery energy. Use Value: 400 W rating handles repetitive flyback spikes; 1.5 W PD enables continuous operation without heatsink in compact adapters. | Use Scenario: Primary protection for DSL PHY interface against lightning-induced surges on twisted-pair lines. IC Role / Device Role / Timing Role: First-stage unidirectional suppressor on line driver output, coordinated with gas discharge tube (GDT) upstream. Use Value: 17.8 A IPPM provides robust coordination with GDT let-through; DO-41 form factor allows manual placement in telecom line card layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Surface-mount SMB package (vs. axial DO-41); same VBR range (15.2–16.8 V), identical 400 W PPPM, but lower IPPM (17.3 A vs. 17.8 A) and higher VC (26.0 V vs. 22.5 V) | Requires PCB redesign for SMD footprint; better suited for high-density consumer boards where space is constrained | Select SMBJ16A when automated assembly and board area savings outweigh clamping voltage margin loss. |
| 1N6267A | Legacy DO-41 TVS with same VBR (15.2–16.8 V) and VC (22.5 V), but lower PPPM (300 W) and no AEC-Q101 qualification | Lacks automotive qualification and reduced surge margin; suitable only for cost-sensitive industrial controls without automotive compliance needs | Choose 1N6267A only for legacy replacement in non-automotive designs where 300 W surge rating suffices. |
Compared with SMBJ16A and 1N6267A, the P4KE16-E3/54 delivers superior clamping voltage (22.5 V), full AEC-Q101 qualification, and highest surge margin (400 W), making it optimal for new automotive and high-reliability industrial designs requiring proven axial-leaded robustness.

FAQ
What is the breakdown voltage tolerance of the P4KE16-E3/54?
The P4KE16-E3/54 has a specified breakdown voltage range of 15.2 V to 16.8 V at 1.0 mA test current (VBR min/max), representing ±5.0% tolerance around the nominal 16 V rating. This tight spread ensures consistent clamping behavior across production lots and supports reliable design margins for 15 V systems.
Does the P4KE16-E3/54 meet automotive qualification standards?
Yes, the P4KE16-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number 88365, Revision 16-Sep-2021). The "E3" suffix denotes RoHS-compliant commercial grade with JESD 201 class 1A whisker resistance; AEC-Q101 validation confirms suitability for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of the P4KE16-E3/54 under surge conditions?
The P4KE16-E3/54 exhibits a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current of 17.8 A using the standard 10/1000 µs waveform. This value is measured under controlled test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the P4KE16-E3/54 be used in bidirectional configurations?
No, the P4KE16-E3/54 is a unidirectional TVS diode, indicated by the absence of "CA" suffix (e.g., P4KE16CA would be bidirectional). Its cathode band marks the avalanche terminal; applying reverse voltage beyond VBR triggers clamping, while forward bias conducts like a standard diode with VF ≤3.5 V at 25 A.
What is the thermal resistance specification for the P4KE16-E3/54?
The P4KE16-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W (with 10 mm lead length). These values govern temperature rise under steady-state power dissipation and are essential for calculating safe operating area in thermally constrained layouts.
