Overview
P4KE400C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 342 V standoff voltage (VWM), 380–420 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), and clamps to ≤548 V at 0.73 A peak pulse current - deployed in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE400C-E3/54 datasheet, P4KE400C-E3/54 pinout, P4KE400C-E3/54 application, or P4KE400C-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, bidirectional clamping behavior, AEC-Q101 qualification status, and direct alternative part comparisons for ESD and lightning transient protection design.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical bidirectional avalanche breakdown, enabling suppression of both positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for repeatable clamping under repetitive 0.01% duty cycle surges.
The P4KE400C-E3/54 exhibits a maximum clamping voltage (VC) of 548 V at IPPM = 0.73 A (10/1000 μs), with thermal resistance RθJL = 66 °C/W and operating junction temperature range from –55 °C to +175 °C - supporting high-reliability deployment in under-hood automotive and industrial control environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400CA | DO-214AA package; 600 W PPPM; lower VC (520 V at 0.75 A); higher capacitance (~100 pF). | Better suited for space-constrained PCBs but less optimal for high-frequency signal lines due to higher junction capacitance. | Select SMBJ400CA when board area is limited and clamping voltage margin <28 V is acceptable. |
| 1.5KE400CA | DO-201AD package; 1500 W PPPM; same VWM/VBR range; higher IFSM (200 A) but larger footprint and higher thermal resistance (RθJA = 125 °C/W). | Preferred for high-energy industrial surge environments (e.g., factory floor mains coupling) where 400 W is insufficient. | Choose 1.5KE400CA only when system-level surge tests exceed IEC 61000-4-5 Level 4 and DO-41 thermal limits are exceeded. |

FAQ
What does the "C" suffix indicate in P4KE400C-E3/54?
The "C" in P4KE400C-E3/54 denotes bidirectional configuration - meaning the device provides symmetrical clamping for both positive and negative transients without polarity sensitivity. Unlike unidirectional variants (e.g., P4KE400A-E3/54), the P4KE400C-E3/54 has no cathode marking and functions identically regardless of terminal orientation, simplifying layout in AC-coupled or differential signal paths.
Is P4KE400C-E3/54 RoHS-compliant and halogen-free?
Yes, P4KE400C-E3/54 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per IEC 61249-2-21. The molding compound meets UL 94 V-0 flammability rating, and matte tin-plated leads satisfy J-STD-002 solderability requirements - confirmed in Vishay document 88365, revision 16-Sep-2021.
What is the maximum clamping voltage of P4KE400C-E3/54 under standard test conditions?
The maximum clamping voltage (VC) of P4KE400C-E3/54 is 548 V, measured at a peak pulse current (IPPM) of 0.73 A using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage rating selection in protected circuits.
Can P4KE400C-E3/54 replace P4KE400A-E3/54 in a design?
No - P4KE400C-E3/54 is bidirectional while P4KE400A-E3/54 is unidirectional; they are not functionally interchangeable without circuit review. The unidirectional version requires correct anode/cathode orientation and conducts forward current, whereas the P4KE400C-E3/54 blocks in both directions until breakdown. Swapping may cause unintended conduction or failed protection in DC-biased lines.
Does P4KE400C-E3/54 meet AEC-Q101 for automotive use?
Yes, P4KE400C-E3/54 is explicitly AEC-Q101 qualified per Vishay documentation (note "(1) AEC-Q101 qualified" in datasheet section "RATINGS AND CHARACTERISTICS CURVES"). This includes stress testing for temperature cycling, high-temperature reverse bias, and ESD per JESD22-A114, validating its suitability for under-hood and body-control module applications.
