Product details
Overview
P4KE11A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 10.5 V minimum breakdown voltage (VBR), 9.40 V maximum stand-off voltage (VWM), 15.6 V clamping voltage (VC) at 25.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and ICs in automotive and industrial power supplies.
For engineers reviewing the P4KE11A-E3/54 datasheet, P4KE11A-E3/54 pinout, P4KE11A-E3/54 application, or P4KE11A-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, thermal resistance data, and real-world protection use cases - all confirmed from Vishay's official document #88365 (Rev. 16-Sep-2021).
Technical Context
The P4KE11A-E3/54 operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to ESD and inductive switching transients. Its 10/1000 μs waveform capability supports 400 W non-repetitive surge handling, while the 66 °C/W junction-to-lead thermal resistance enables reliable operation up to 175 °C junction temperature.
It exhibits 0.075 %/°C temperature coefficient of breakdown voltage and 5.0 μA maximum reverse leakage at 9.40 V stand-off, ensuring stable clamping behavior across automotive temperature ranges. The device is RoHS-compliant (E3 suffix), meets JESD 201 Class 1A whisker test, and is rated for 40 A peak forward surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1.0 mA test current - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 9.40 V maximum - ensures no conduction during normal 9 V system operation, minimizing standby leakage |
| VC @ IPPM | 15.6 V at 25.6 A - limits downstream voltage stress to safe levels for 12 V rail components like microcontrollers |
| PPPM | 400 W with 10/1000 μs waveform - sustains high-energy transients from relay coil collapse or load dump |
| IFSM | 40 A peak forward surge (8.3 ms half-sine) - withstands repetitive inrush events without degradation |
| TJ max | 175 °C - supports under-hood automotive environments and high-temperature industrial enclosures |
| RθJL | 66 °C/W - enables direct PCB trace heat sinking without external heatsink for moderate duty cycles |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with matte tin-plated leads; cathode indicated by color band; compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or transient clamping in reverse-biased mode | Connected to protected line (e.g., 12 V supply rail); must be routed with low-inductance path to ground reference |
| Cathode | Current exit point; marked with color band; reverse-biased during normal operation | Connected to system ground; determines polarity-sensitive placement - incorrect orientation disables protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics over 1000+ surge events without parameter drift |
| AEC-Q101 qualified (E3 suffix) | Validated for automotive powertrain and body electronics per stress test requirements including HTOL and TC |
| 400 W peak pulse power (10/1000 μs) | Clamps 100 V/10 A transients typical of ISO 7637-2 Pulse 1/2a/5a without failure or parametric shift |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), critical for protecting sensitive gate oxides |
| Solder dip 275 °C max. (10 s) | Supports standard wave soldering processes without delamination or junction damage |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Guarding |

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; 10 V VWM; 17.0 V VC @ 23.5 A; 600 W PPPM | Higher power rating but larger footprint; better suited for board space-constrained designs requiring >400 W margin | Select SMBJ10A when higher surge margin and surface-mount assembly are prioritized over through-hole compatibility |
| 1N6267A | Same DO-41 package; 10 V VWM; 17.0 V VC @ 23.5 A; 400 W PPPM; no AEC-Q101 qualification | Lacks automotive qualification; suitable only for commercial-grade consumer or industrial equipment | Choose 1N6267A for cost-sensitive non-automotive applications where AEC-Q101 compliance is not required |
Compared with SMBJ10A and 1N6267A, the P4KE11A-E3/54 provides tighter VBR tolerance (10.5–11.6 V vs. ±5 %), AEC-Q101 validation, and optimized thermal resistance (66 °C/W) for lead-mounted reliability - making it the preferred choice for automotive and high-reliability industrial deployments where DO-41 through-hole mounting is specified.

FAQ
What is the maximum clamping voltage of the P4KE11A-E3/54 under surge conditions?
The P4KE11A-E3/54 has a maximum clamping voltage (VC) of 15.6 V at 25.6 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document #88365 and ensures downstream components see limited overvoltage during transient events. The P4KE11A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P4KE11A-E3/54 suitable for automotive applications?
Yes, the P4KE11A-E3/54 is AEC-Q101 qualified (E3 suffix), validated for automotive powertrain and body electronics per high-temperature operating life (HTOL), temperature cycling (TC), and mechanical shock requirements. Its 175 °C maximum junction temperature and 66 °C/W thermal resistance make the P4KE11A-E3/54 appropriate for under-hood and dashboard-mounted modules.
How does the P4KE11A-E3/54 differ from bidirectional TVS diodes like P4KE11CA?
The P4KE11A-E3/54 is unidirectional and features a cathode band for polarity-sensitive installation, whereas P4KE11CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The P4KE11A-E3/54 offers lower leakage (5.0 μA at 9.4 V) versus bidirectional variants and is intended for DC line protection where reverse conduction must be blocked during normal operation.
What is the thermal resistance specification for the P4KE11A-E3/54?
The P4KE11A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with lead length L = 10 mm. This value enables effective heat dissipation through PCB copper pours or chassis connections without requiring additional heatsinking. The P4KE11A-E3/54 also specifies 100 °C/W junction-to-ambient resistance under standard test conditions.
Can the P4KE11A-E3/54 be used in place of the P4KE10A or P4KE12A?
The P4KE11A-E3/54 is not a direct replacement for P4KE10A (VWM = 8.55 V) or P4KE12A (VWM = 10.2 V) due to its specific 9.40 V maximum stand-off voltage and 10.5–11.6 V breakdown range. Substitution requires verifying that system operating voltage tolerances and clamping margins remain within design limits - the P4KE11A-E3/54 should only replace other P4KE11A variants with identical E3/54 packaging and qualification.
