Product details
Overview
P6KE16A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 600 W peak pulse power (10/1000 μs), 15.2–16.8 V breakdown voltage at 1 mA, 13.6 V stand-off voltage, 22.5 V maximum clamping voltage at 26.7 A, and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the P6KE16A-E3/54 datasheet, P6KE16A-E3/54 pinout, P6KE16A-E3/54 application, or P6KE16A-E3/54 equivalent, this device is selected for robust overvoltage protection in DC power rails, automotive sensor interfaces, industrial I/O lines, and consumer equipment where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.44), and AEC-Q101 qualification are critical.
Technical Context
The P6KE16A-E3/54 uses a glass-passivated silicon junction to achieve stable avalanche breakdown with tight VBR tolerance (±5 %) and low temperature coefficient (0.086 %/°C). Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction path concerns.
It delivers 600 W surge capability under standardized 10/1000 μs waveform with 0.01 % duty cycle, and exhibits very low incremental surge resistance - enabling effective clamping of transient energy before downstream components experience damaging overvoltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 15.2 V / 16.8 V at IT = 1 mA - defines reliable avalanche initiation range for predictable clamping onset |
| VWM | 13.6 V - maximum continuous reverse working voltage; ensures no leakage-induced stress on protected circuit |
| VC @ IPPM | 22.5 V at 26.7 A - clamping voltage during full-rated 600 W transient; limits downstream voltage stress |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 surge immunity requirements |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine); supports high-energy fault clearing |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - thermal resistance junction-to-lead; supports efficient heat transfer to PCB copper when mounted with minimum lead length |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band.

IC Role / Device Role / Timing Role: Mounted directly at connector entry point to shunt surge energy before it enters isolation barriers or FPGA I/O banks. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) up to 4 kV/2 kA without derating or additional filtering. |
| Consumer Power Adapter Input | DC Power Rail Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers subjected to mains-borne surges and hot-plug transients. IC Role / Device Role / Timing Role: Placed across regulated 5 V/9 V/12 V output rails to clamp transient overshoot during regulation loop instability or capacitor failure. Use Value: Limits output voltage excursion to ≤22.5 V during 600 W surge, preventing damage to connected smartphones, tablets, or IoT hubs. | Use Scenario: Protecting 12–24 V DC distribution networks in telecom base stations and network switches from lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Used in parallel with bulk capacitors on main power bus to absorb fast-rising edge energy before it reaches PMICs and FPGAs. Use Value: Maintains system uptime by preventing brownout resets or catastrophic failure during outdoor-installed equipment exposure to indirect lightning strikes. |
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 | Same VBR range (15.2–16.8 V), but SMC (DO-214AB) package; 600 W rating, lower RθJA (50 °C/W vs. 75 °C/W) | Better thermal performance in high-density layouts; requires PCB footprint change from axial DO-15 to surface-mount SMC | Select SMBJ16A when board space is constrained and reflow assembly is used; P6KE16A-E3/54 preferred for through-hole reliability and serviceability |
| 1.5KE16A | Same DO-15 package and electrical specs, but older generation; not AEC-Q101 qualified; 1.5 kW rating (10/1000 μs) vs. 600 W | Higher peak power margin but larger physical size and higher cost; lacks automotive qualification documentation | Choose 1.5KE16A only if legacy design reuse mandates identical form factor and higher surge headroom is required; P6KE16A-E3/54 offers better cost-performance balance and automotive compliance |
Compared with SMBJ16A and 1.5KE16A, the P6KE16A-E3/54 provides optimal trade-off of AEC-Q101 qualification, DO-15 through-hole robustness, and verified 600 W surge handling - making it ideal for new automotive and industrial designs requiring traceable compliance and long-term supply stability.

FAQ
What is the breakdown voltage range of the P6KE16A-E3/54?
The P6KE16A-E3/54 has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at test current IT = 1 mA, measured per ANSI/IEEE C62.35. This tight ±5 % tolerance ensures consistent clamping behavior across production lots and operating temperatures, supporting reliable design margining in 12 V system protection.
Is the P6KE16A-E3/54 suitable for automotive applications?
Yes, the P6KE16A-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number: 88369, Revision: 27-Sep-2021), confirming its reliability for automotive use including engine control units, body electronics, and ADAS sensors. The E3 suffix denotes RoHS-compliant commercial grade with AEC-Q101 validation, and the device operates from –55 °C to +175 °C.
What does the "-E3/54" suffix mean in P6KE16A-E3/54?
The "-E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 4000 units. This ordering code ensures traceable, standardized logistics and compatibility with automated pick-and-place systems.
How does the clamping voltage of P6KE16A-E3/54 compare to its breakdown voltage?
The P6KE16A-E3/54 clamps to a maximum of 22.5 V at its rated peak pulse current (26.7 A), yielding a clamping ratio (VC/VBRmin) of ~1.44. This low ratio reflects efficient avalanche conduction and minimal voltage overshoot - critical for protecting 15 V-tolerant ICs while maintaining safe margin below absolute maximum ratings.
Can P6KE16A-E3/54 be used in bidirectional configurations?
No, P6KE16A-E3/54 is a unidirectional TVS diode, identified by its cathode band marking. For bidirectional operation, Vishay specifies the CA-suffix variant (e.g., P6KE16CA). Using P6KE16A-E3/54 in AC or floating applications would result in forward conduction during negative half-cycles, potentially causing failure or unintended circuit behavior.
