Product details
Overview
P4KE10A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 400 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 8.55 V stand-off voltage - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE10A-E3/54 datasheet, P4KE10A-E3/54 pinout, P4KE10A-E3/54 application, or P4KE10A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (66 °C/W junction-to-lead), unidirectional polarity marking, and AEC-Q101 qualification status for automotive use.
Technical Context
The P4KE10A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, triggering conduction when reverse voltage exceeds its 9.5–10.5 V breakdown range at 1 mA test current. Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 μs transients at 0.01 % duty cycle.
Designed for unidirectional protection only, it exhibits 3.5 V forward voltage at 25 A surge, 1.5 W steady-state power dissipation on infinite heatsink, and operates across –55 °C to +175 °C junction temperature range - validated per JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 9.5 V / 10.5 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 10 μA |
| VC @ IPPM | 14.5 V at 27.6 A - clamping voltage during 400 W transient, ensuring protected IC stays below 16 V absolute max |
| PPPM | 400 W (10/1000 μs) - peak surge energy handling capacity without degradation |
| RθJL | 66 °C/W - enables thermal design with lead-mounted PCB layout for sustained 1.5 W dissipation |
| TJ max | +175 °C - supports operation in under-hood automotive environments and high-ambient industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package, 600 W PPPM, 17.0 V VC @ 35.3 A, RθJA = 40 °C/W | Higher power handling but larger footprint; better suited for board space-constrained designs needing >400 W margin | Select SMBJ10A when surge energy exceeds 400 W or when lower thermal resistance is required for high ambient temperatures. |
| 1.5KE10A | Same DO-41 package, 1500 W PPPM, 17.0 V VC @ 88.2 A, higher IFSM (100 A) | Higher surge robustness but slower response due to larger junction capacitance; not AEC-Q101 qualified | Choose 1.5KE10A for non-automotive industrial applications demanding higher single-pulse immunity without qualification requirements. |
Compared with SMBJ10A and 1.5KE10A, the P4KE10A-E3/54 offers optimal balance of AEC-Q101 compliance, compact DO-41 footprint, and verified 400 W surge capability - making it preferred for cost-sensitive automotive and industrial designs where qualification and form factor are critical.

FAQ
What is the breakdown voltage range of the P4KE10A-E3/54?
The P4KE10A-E3/54 has a guaranteed breakdown voltage range of 9.5 V to 10.5 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in safety-critical circuits like automotive power supplies.
Is the P4KE10A-E3/54 suitable for automotive applications?
Yes, the P4KE10A-E3/54 is AEC-Q101 qualified and RoHS-compliant, making it suitable for automotive applications including engine control units, body control modules, and infotainment power rails. Its –55 °C to +175 °C operating range and JESD 201 class 1A whisker resistance meet stringent automotive reliability requirements.
What is the maximum clamping voltage of the P4KE10A-E3/54 during a surge event?
The P4KE10A-E3/54 clamps to a maximum of 14.5 V at its rated peak pulse current of 27.6 A (10/1000 μs waveform). This value is critical for ensuring protected ICs remain within their absolute maximum voltage ratings during transient events such as ISO 7637-2 load dump pulses.
Does the P4KE10A-E3/54 have bidirectional capability?
No, the P4KE10A-E3/54 is a unidirectional TVS diode. Bidirectional variants in the same family use the "CA" suffix (e.g., P4KE10CA). The cathode band on the P4KE10A-E3/54 body indicates polarity, and it must be oriented with cathode toward the protected circuit node for proper operation.
What packaging format is used for the P4KE10A-E3/54?
The P4KE10A-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with 5500 units per reel (package code "54"). This format supports automated SMT placement and is compatible with standard pick-and-place equipment used in high-volume electronics manufacturing.
