Product details
Overview
P4KE200-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 200 V breakdown voltage (VBR min/max = 190–210 V), 171 V stand-off voltage (VWM), 274 V maximum clamping voltage (VC) at 1.5 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE200-E3/54 datasheet, P4KE200-E3/54 pinout, P4KE200-E3/54 application, or P4KE200-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, DO-41 mechanical compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression in DC power rails and low-speed signal paths. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, while thermal resistance RθJL = 66 °C/W supports reliable energy dissipation during repetitive 0.01% duty cycle surges.
The P4KE200-E3/54 is rated for TJ = −55 °C to +175 °C operation, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Its forward voltage VF = 5.0 V at 25 A (per spec note 3) confirms suitability for high-current transient events without latch-up in unidirectional configurations.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA package; 200 V VBR; 300 W PPPM; 1.0 A IPPM; surface-mount only | Requires PCB re-layout for SMD footprint; lower surge rating limits use in high-energy automotive load dump | Select when board space is constrained and surge energy does not exceed 300 W |
| 1.5KE200A | DO-204AL package; same VBR range; 1500 W PPPM; 6.2 A IPPM; through-hole compatible | Higher surge capacity suits heavy-duty industrial motor drives but increases cost and size vs. P4KE200-E3/54 | Choose for legacy designs requiring >400 W headroom or where 1.5KE series is already qualified |
Compared with SMBJ200A and 1.5KE200A, the P4KE200-E3/54 offers optimal balance of DO-41 through-hole compatibility, 400 W surge rating, and AEC-Q101 qualification - making it preferred for new automotive and industrial designs where cost, reliability, and mechanical fit must align.

FAQ
What is the clamping voltage of the P4KE200-E3/54 under standard test conditions?
The P4KE200-E3/54 has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 1.5 A using a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4KE200-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P4KE200-E3/54 suitable for automotive applications?
Yes, the P4KE200-E3/54 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its DO-41 package, −55 °C to +175 °C operating range, and 400 W surge rating meet critical requirements for under-hood and chassis-mounted systems. The P4KE200-E3/54 is explicitly listed in the AEC-Q101 qualified variants table in revision 16-Sep-2021 of document 88365.
How does the P4KE200-E3/54 differ from bidirectional TVS diodes like P4KE200CA?
The P4KE200-E3/54 is unidirectional and features a cathode band marking, enabling asymmetric clamping - conducting forward current below ~5.0 V while suppressing reverse surges above 190 V. In contrast, P4KE200CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. The P4KE200-E3/54 is selected when protection is needed only on one side of a DC rail, offering tighter VBR tolerance and lower leakage than its bidirectional counterpart.
What is the thermal resistance specification for the P4KE200-E3/54?
The P4KE200-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, as specified in the Thermal Characteristics section of Vishay document 88365. This parameter quantifies how effectively heat transfers from the silicon junction to the lead frame during surge events. It supports thermal design calculations for PCB copper pour sizing and ensures safe operation up to 175 °C junction temperature. The P4KE200-E3/54 does not specify RθJA for free-air conditions due to its intended use with lead-based heat sinking.
Does the P4KE200-E3/54 require derating at elevated ambient temperatures?
Yes, the P4KE200-E3/54 requires derating above TA = 25 °C per Figure 2 in Vishay document 88365. Its peak pulse power capability decreases linearly to zero at TJ = 175 °C, with a defined derating curve showing 50% power retention at approximately 100 °C ambient when mounted on standard PCB leads. Designers must apply this derating when deploying the P4KE200-E3/54 in high-temperature enclosures such as engine compartments or sealed industrial cabinets.
