Product details

Overview

P4KE11-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 10.5 V maximum clamping voltage at 25.6 A peak pulse current, 9.40 V stand-off voltage, and 400 W peak pulse power rating with 10/1000 μs waveform.

For engineers reviewing the P4KE11-E3/54 datasheet, P4KE11-E3/54 pinout, P4KE11-E3/54 application, or P4KE11-E3/54 equivalent, key selection criteria include breakdown voltage tolerance (10.5–11.6 V), low clamping ratio (VC/VBR ≈ 1.05), AEC-Q101 qualification status, DO-41 mechanical compatibility, and 175 °C max junction temperature for automotive-grade reliability.

Technical Context

This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 10.5–11.6 V breakdown range at 1.0 mA test current. Its glass-passivated junction ensures stable leakage (<5.0 μA at 9.40 V) and fast response time to sub-nanosecond transients.

Thermal design relies on RθJL = 66 °C/W and RθJA = 100 °C/W, supporting operation from –55 °C to +175 °C. It handles 40 A non-repetitive forward surge (8.3 ms half-sine) and dissipates 1.5 W continuously on infinite heatsink at TL = 75 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR min/max	10.5 V / 11.6 V at 1.0 mA - defines precise overvoltage trip threshold for protection circuit design
V_WM	9.40 V - maximum continuous reverse operating voltage before leakage rises significantly
V_C @ I_PPM	15.6 V at 25.6 A - clamped voltage during 10/1000 μs surge, limiting downstream IC stress
P_PPM	400 W - peak transient energy absorption capability under standardized surge waveform
I_FSM	40 A - surge current handling for 8.3 ms half-sine, critical for inductive load switching protection
T_J max	+175 °C - enables use in under-hood automotive environments without derating penalties
Leakage I_D	≤5.0 μA at V_WM - ensures minimal standby power loss in battery-powered systems

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ10A	DO-214AA package; 10 V V_WM, 11.1 V V_BR min, 17.0 V V_C @ 23.5 A; 600 W P_PPM	Higher power rating but larger footprint; lower clamping ratio (1.53×V_BR) vs. P4KE11-E3/54 (1.41×V_BR)	Select SMBJ10A when board space allows and higher surge margin is required; not drop-in due to different package and pin spacing.
1.5KE11A	DO-201AD package; identical V_WM/V_BR/V_C specs but 1500 W P_PPM; 10/1000 μs rating	Larger case size (5.6 mm Ø × 9.5 mm L); higher thermal mass supports longer surge durations	Choose 1.5KE11A for high-energy transients where PCB layout accommodates larger DO-201AD footprint.

FAQ

What is the breakdown voltage range for P4KE11-E3/54?

The P4KE11-E3/54 has a guaranteed breakdown voltage range of 10.5 V to 11.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in circuits protecting 9–12 V rails. The value is confirmed in Vishay's official datasheet revision 16-Sep-2021, document 88365.

Is P4KE11-E3/54 qualified for automotive applications?

Yes, P4KE11-E3/54 is AEC-Q101 qualified per note (1) in the Vishay datasheet. The "E3" suffix denotes RoHS-compliant commercial grade with JESD 201 class 1A whisker testing, and the HE3 variant adds full AEC-Q101 qualification. Engineers can deploy P4KE11-E3/54 in engine control units, body electronics, and infotainment systems where automotive-grade reliability is mandated.

What is the maximum clamping voltage of P4KE11-E3/54 under surge conditions?

The maximum clamping voltage (V_C) of P4KE11-E3/54 is 15.6 V at 25.6 A peak pulse current with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream components during worst-case transient events and is critical for ensuring protected ICs remain within absolute maximum ratings. It is specified in Table 1 of the Vishay P4KE6.8A–P4KE540A datasheet.

Does P4KE11-E3/54 have bidirectional capability?

No, P4KE11-E3/54 is a unidirectional transient voltage suppressor. Its part number lacks the "CA" suffix (e.g., P4KE11CA), which denotes bidirectional variants. The cathode is marked by a color band, and it conducts only in reverse bias to clamp positive transients on lines referenced to ground. Bidirectional operation requires explicit CA-suffix parts with symmetric V_BR in both directions.

What package type does P4KE11-E3/54 use and what are its key mechanical features?

P4KE11-E3/54 uses the DO-41 (DO-204AL) axial-leaded package: molded epoxy body meeting UL 94 V-0 flammability rating, matte tin-plated leads solderable per J-STD-002, and dimensions of ≥25.4 mm length with 2.0–2.7 mm diameter. Its compact size and industry-standard footprint enable drop-in replacement in legacy designs while supporting manual or automated through-hole assembly.
