Product details
Overview
P6KE27A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary-level overvoltage protection of DC power rails and signal lines. It features a 27 V nominal breakdown voltage (VBR = 25.7–28.4 V at 1 mA), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE27A-E3/73 datasheet, P6KE27A-E3/73 pinout, P6KE27A-E3/73 application, or P6KE27A-E3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal derating above 25 °C ambient, unidirectional polarity marking (cathode band), and compatibility with J-STD-002 solderability requirements for lead-free assembly.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 23.1 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream components. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM).
It delivers 600 W peak pulse power handling per 10/1000 µs waveform with 0.01% duty cycle, supported by 20 °C/W junction-to-lead thermal resistance and 175 °C maximum junction temperature. The device is RoHS-compliant (E3 suffix), qualified to AEC-Q101 for automotive use, and rated for 100 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1 mA - defines precise turn-on threshold for reliable clamping onset without false triggering |
| VWM | 23.1 V - maximum continuous working voltage; must exceed system operating voltage to prevent leakage-induced power loss |
| VC @ IPPM | 37.5 V at 16.0 A - clamping voltage seen by protected circuit during worst-case surge; determines safe margin below IC damage threshold |
| PPPM | 600 W - peak transient energy absorption capability with 10/1000 µs waveform; enables robust protection against ESD, load dump, and inductive switching |
| IPPM | 16.0 A - maximum surge current the device can safely clamp; used to size upstream fusing and verify PCB trace current capacity |
| TJmax | 175 °C - maximum junction temperature; supports operation in under-hood automotive environments and high-power industrial enclosures |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables accurate thermal modeling when mounted on PCB with minimal copper heatsinking |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. Cathode identified by color band at one end; anode is unmarked. Complies with UL 94 V-0 flammability rating and JESD 22-B106 solder dip (275 °C, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current entry point during forward conduction | Connected to ground or lower-potential rail in unidirectional configuration; must be routed with low-inductance path for effective surge diversion |
| Cathode (banded end) | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 24 V supply or CAN_H); polarity marking prevents incorrect installation that would disable protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures ±5% VBR tolerance and <1 µA leakage at VWM, critical for low-power sensor nodes and battery-backed systems |
| 600 W peak pulse power (10/1000 µs) | Provides single-event surge immunity exceeding ISO 7637-2 Pulse 1/2a/5a requirements for 12 V automotive systems |
| AEC-Q101 qualification (E3 suffix) | Validates reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes voltage overshoot during transients, enabling protection of 3.3 V/5 V logic without additional series impedance |
| Solderable per J-STD-002 & JESD 22-B102 | Guarantees consistent wetting and joint integrity in lead-free reflow and wave solder processes across high-volume manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package; 24 V VWM, 38.9 V VC @ 15.4 A; 600 W rating; higher thermal resistance (RθJA = 110 °C/W) | Better suited for surface-mount layouts with space constraints; less effective in high-ambient-temperature environments without heatsinking | Select SMBJ24A when automated SMT assembly is required and board real estate is limited; verify thermal margin at 75 °C ambient. |
| 1.5KE27A | DO-201AD package; identical VBR (25.7–28.4 V), same VC (37.5 V), but higher RθJL (25 °C/W) and larger physical size (10.16 mm length) | Higher mechanical robustness for high-vibration environments; requires larger PCB cutout and manual insertion labor | Choose 1.5KE27A where mechanical durability outweighs size penalty, e.g., railway signaling or heavy machinery controls. |

FAQ
What is the maximum clamping voltage of the P6KE27A-E3/73 under surge conditions?
The P6KE27A-E3/73 has a maximum clamping voltage (VC) of 37.5 V when subjected to its rated peak pulse current of 16.0 A with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on the protected circuit during transient events. Designers must ensure this clamping level remains below the absolute maximum rating of downstream components. The P6KE27A-E3/73 achieves this with low dynamic impedance and fast response time.
Is the P6KE27A-E3/73 suitable for automotive applications?
Yes, the P6KE27A-E3/73 is AEC-Q101 qualified (E3 suffix denotes commercial grade with AEC-Q101 compliance), making it suitable for automotive applications including engine control units, body electronics, and sensor interfaces. It operates across –55 °C to +175 °C junction temperature range and withstands 100 A non-repetitive forward surge current (8.3 ms half-sine). The P6KE27A-E3/73 also meets JESD 201 class 1A whisker testing and UL 497B recognition for surge protectors.
How does the P6KE27A-E3/73 differ from bidirectional TVS diodes like P6KE27CA?
The P6KE27A-E3/73 is unidirectional and features a cathode band for polarity identification, while P6KE27CA is bidirectional with no polarity marking and symmetric clamping in both directions. Unidirectional types like P6KE27A-E3/73 offer lower leakage current and tighter VBR tolerance, making them ideal for DC rail protection. Bidirectional variants are used for AC lines or differential signals. The P6KE27A-E3/73 cannot substitute for P6KE27CA in AC-coupled applications without circuit redesign.
What is the thermal resistance specification for the P6KE27A-E3/73?
The P6KE27A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W. These values enable accurate thermal modeling during PCB layout - especially important when operating near maximum power dissipation (5.0 W) or elevated ambient temperatures. Derating curves in the datasheet show power reduction above 25 °C ambient, and the P6KE27A-E3/73 maintains full rating up to 75 °C lead temperature.
Can the P6KE27A-E3/73 be used in place of the older P6KE27A without design changes?
Yes, the P6KE27A-E3/73 is a direct replacement for legacy P6KE27A variants, retaining identical electrical specifications, DO-15 package dimensions, and pinout. The "E3" suffix indicates RoHS compliance and JESD 201 class 1A whisker testing, while "/73" denotes tape-and-reel packaging (73 = 7-inch reel). No PCB layout, schematic, or firmware modifications are needed when upgrading to P6KE27A-E3/73, and the P6KE27A-E3/73 maintains full compatibility with existing assembly processes.
