Product details
Overview
P6KE160A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1.0 mA), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and DC power rail protection.
For engineers reviewing the P6KE160A-E3/54 datasheet, P6KE160A-E3/54 pinout, P6KE160A-E3/54 application, or P6KE160A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal derating above 25 °C ambient, junction-to-lead thermal resistance (20 °C/W), and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, responding to transients in <1 ps with low incremental surge resistance. Its unidirectional polarity uses a cathode band marking, and it complies with AEC-Q101 for automotive-grade reliability.
Rated for -55 °C to +175 °C operating junction temperature, it delivers 5.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). Clamping performance is specified at 2.7 A IPPM, where VC ≤ 219 V ensures safe voltage limiting for downstream 200 V-rated components.
Key Specifications

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 | DO-214AA package (SMB), 152–168 V VBR, 219 V VC at 2.7 A, same PPPM but lower IFSM (100 A vs. SMBJ's 79 A) | Surface-mount footprint; requires PCB rework for replacement; better high-frequency decoupling due to lower parasitic inductance | Select when board space is constrained and SMT assembly is preferred; verify thermal pad layout for 5.0 W dissipation |
| 1.5KE160A | Same DO-15 package, identical VWM/VBR/VC specs, but 1500 W PPPM (10/1000 μs) and higher IFSM (200 A) | Higher surge margin for infrequent but extreme events (e.g., direct lightning coupling); larger junction area increases capacitance (~100 pF vs. ~50 pF) | Choose when legacy 1.5KE footprint is fixed and enhanced surge headroom justifies added cost and capacitance trade-off |
Compared with SMBJ160A and 1.5KE160A, P6KE160A-E3/54 offers optimal balance of axial-leaded manufacturability, 600 W surge capability, and low-cost commercial qualification - making it ideal for high-volume industrial and automotive applications where DO-15 compatibility and AEC-Q101 compliance are required without over-engineering.

FAQ
What is the clamping voltage of P6KE160A-E3/54 at its rated peak pulse current?
The P6KE160A-E3/54 has a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 2.7 A using the 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and ensures predictable overvoltage limiting for downstream components rated up to 200 V. The P6KE160A-E3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE160A-E3/54 suitable for automotive applications?
Yes, P6KE160A-E3/54 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive environments including engine control units, body electronics, and sensor interfaces. Its -55 °C to +175 °C junction temperature range, 100 A surge rating, and glass-passivated junction meet stringent automotive reliability requirements. The E3 suffix denotes RoHS-compliant commercial grade with AEC-Q101 validation.
How does the P6KE160A-E3/54 differ from bidirectional TVS diodes like P6KE160CA?
P6KE160A-E3/54 is unidirectional with cathode band marking and conducts only in reverse bias, making it ideal for DC rail or signal-line-to-ground protection. In contrast, P6KE160CA is bidirectional, symmetric in both directions, and used for AC lines or differential signals. The P6KE160A-E3/54 has lower leakage at VWM and is not rated for bidirectional surge handling - substituting one for the other requires circuit topology verification.
What is the thermal resistance and how does it affect PCB layout for P6KE160A-E3/54?
The P6KE160A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt dissipated raises the junction temperature 20 °C above the lead temperature. For reliable operation, PCB traces connected to both leads should be wide and short, with thermal vias to inner ground planes - especially critical when operating near its 5.0 W steady-state limit or during repetitive surges. The P6KE160A-E3/54 thermal performance is validated per Figure 5 in Vishay doc 88369.
Can P6KE160A-E3/54 be used in place of P6KE150A or P6KE170A?
P6KE160A-E3/54 is part of a standardized family with adjacent variants differing only in VWM/VBR ratings - P6KE150A (128 V VWM) and P6KE170A (145 V VWM). Substitution is feasible if the protected circuit's maximum operating voltage falls within the new device's VWM margin and clamping voltage remains below the IC's absolute maximum rating. The P6KE160A-E3/54 provides 136 V standoff, balancing margin and responsiveness for 12–16 V systems.
