Product details
Overview
P4KE160A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR), 219 V maximum clamping voltage at 1.8 A peak pulse current, 400 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4KE160A-E3/54 datasheet, P4KE160A-E3/54 pinout, P4KE160A-E3/54 application, or P4KE160A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, IPPM derating above 25 °C, thermal resistance (RθJL = 66 °C/W), and DO-41 lead-form compatibility with manual or wave-solder assembly.
Technical Context
This device operates as a silicon avalanche diode, triggered when reverse voltage exceeds its specified VBR range (152–168 V at 1.0 mA test current). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 136 V).
It delivers 400 W transient suppression under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and supports surge currents up to 1.8 A while maintaining clamping below 219 V - critical for protecting downstream MOSFETs, microcontrollers, and sensor interfaces against inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for safe DC rail protection. |
| VBR (min/max) | 152 V / 168 V at 1.0 mA - Confirmed avalanche onset range; defines minimum overvoltage threshold for reliable triggering. |
| VC @ IPPM | 219 V at 1.8 A - Clamped voltage during 10/1000 μs surge; must remain below protected device's absolute max rating. |
| PPPM | 400 W - Peak transient power handling capability; determines survivability of defined lightning or EFT pulses. |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance; enables estimation of temperature rise under sustained 1.5 W steady-state dissipation. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling and HTRB. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W PPPM; RθJA = 40 °C/W. | Requires PCB rework for SMT assembly; better thermal performance in compact layouts; not axial-leaded. | Select SMBJ160A when board space is constrained and automated assembly is used; verify pad thermal relief for 1.5 W steady-state dissipation. |
| 1.5KE160A | Same DO-41 package and VWM/VBR ratings, but higher 1500 W PPPM; larger die; higher IFSM (100 A vs. 40 A). | Overqualified for 400 W threat models; higher cost and larger junction capacitance may affect high-speed signal lines. | Choose 1.5KE160A only when legacy designs require backward compatibility or when surge threats exceed IEC 61000-4-5 Level 4. |
Compared with SMBJ160A and 1.5KE160A, the P4KE160A-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 compliance, and 400 W surge handling - making it ideal for cost-sensitive, high-reliability automotive and industrial through-hole applications where thermal constraints permit DO-41 mounting.

FAQ
What is the clamping voltage of the P4KE160A-E3/54 under standard surge conditions?
The P4KE160A-E3/54 has a maximum clamping voltage (VC) of 219 V at 1.8 A peak pulse current (IPPM) using the 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 - critical for ensuring compatibility with downstream ICs rated for ≤28 V or ≤36 V absolute maximum.
Is the P4KE160A-E3/54 suitable for automotive applications?
Yes, the P4KE160A-E3/54 is AEC-Q101 qualified (per note on page 3 of Vishay document 88365), confirming its reliability for automotive use. Its DO-41 package, 175 °C max junction temperature, and validated surge performance make it appropriate for engine control units, body control modules, and infotainment power rails where unidirectional transient suppression is required.
How does the P4KE160A-E3/54 differ from bidirectional TVS diodes like P4KE160CA?
The P4KE160A-E3/54 is unidirectional and features a cathode band for polarity identification; it conducts only in reverse bias above VBR and blocks forward current up to 5.0 V. In contrast, P4KE160CA is bidirectional with symmetrical clamping in both directions and no polarity marking - used where AC signals or dual-polarity transients require protection without DC bias constraints.
What is the thermal resistance of the P4KE160A-E3/54, and how does it impact layout design?
The P4KE160A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This means that under 1.5 W steady-state dissipation, the junction rises ~100 °C above lead temperature. Layouts should ensure adequate copper area on both leads and avoid thermally isolating the device - especially important in automotive under-hood applications where ambient temperatures exceed 85 °C.
Can the P4KE160A-E3/54 be used in place of the older P4KE160A without design changes?
Yes, the P4KE160A-E3/54 is a direct replacement for P4KE160A, sharing identical electrical specifications, DO-41 package dimensions, and pinout. The "E3/54" suffix denotes RoHS-compliant matte tin plating and packaging in 13″ paper tape/reel (5500 pcs), with no functional or mechanical differences affecting schematic or layout design.
