Product details
Overview
P6KE250A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 250 V standoff voltage (VWM = 214 V), 237–263 V breakdown voltage at 1 mA, 344 V maximum clamping voltage at 1.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive engine control units to protect microcontroller I/O against load dump transients.
For engineers reviewing the P6KE250A-E3/54 datasheet, P6KE250A-E3/54 pinout, P6KE250A-E3/54 application, or P6KE250A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, DO-15 package mechanical compatibility, and AEC-Q101 qualification status for automotive use.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 214 V), but avalanches within <1 ns when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR and low leakage (<1 μA at VWM), while the DO-15 package enables direct leaded mounting on PCBs with minimal board space.
The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine), delivers 5.0 W steady-state power dissipation at TL = 75 °C, and exhibits +0.110 %/°C temperature coefficient of VBR - enabling predictable clamping behavior across -55 °C to +175 °C operating junction range without derating ambiguity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 214 V - maximum continuous DC or RMS voltage the device blocks without conduction; sets upper limit for protected circuit operating voltage. |
| VBR (Breakdown Voltage) | 237–263 V at 1 mA - precise avalanche onset range defining clamping initiation threshold under transient stress. |
| VC (Clamping Voltage) | 344 V at IPPM = 1.7 A (10/1000 μs) - peak voltage seen by downstream circuit during worst-case surge; determines required IC overvoltage margin. |
| PPPM (Peak Pulse Power) | 600 W - maximum single-pulse energy handling capability; validates robustness against ISO 7637-2 Pulse 5a load dump events. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - withstands repetitive inductive switch-off surges without degradation; supports engine ECU relay/coil drive protection. |
| RθJL (Junction-to-Lead) | 20 °C/W - enables accurate thermal design for lead-mounted heatsinking; critical for sustained surge duty in enclosed automotive modules. |
| TJ max. | +175 °C - qualified for under-hood environments; eliminates need for derating in high-ambient engine bay applications. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reference terminal for unidirectional clamping | Connected to ground or low-side return path; defines polarity-sensitive protection direction. |
| Cathode (non-banded end) | Protected line connection point | Connected to the line being safeguarded (e.g., 24 V battery rail); conducts surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 μA), and long-term reliability under thermal cycling in automotive environments. |
| 600 W peak pulse power (10/1000 μs) | Validates compliance with ISO 7637-2 Pulse 5a (load dump) requirements for 24 V systems without external heat sinking. |
| AEC-Q101 qualified (E3 suffix variant) | Confirms qualification for automotive electronic modules including powertrain, body control, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD or inductive kick), improving protection fidelity. |
| Solder dip rated 275 °C / 10 s | Supports standard wave soldering processes without parametric shift or delamination risk. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Digital Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250A | DO-214AA package (smaller footprint), same VWM (214 V), slightly higher VC (354 V at 1.6 A), lower RθJA (50 °C/W vs. 75 °C/W). | Better suited for space-constrained PCBs; requires tighter layout for thermal management due to smaller thermal mass. | Select SMBJ250A when board area is limited and thermal vias can be added; retain P6KE250A-E3/54 for legacy DO-15 footprints or higher surge repetition tolerance. |
| 1.5KE250A | Same DO-15 package, identical VWM/VBR/VC specs, but rated for 1500 W peak power (10/1000 μs) and 100 A IFSM - higher surge margin. | Overqualified for basic load dump; adds cost and size without benefit unless system faces extreme surge repetition or combined lightning + load dump stress. | Choose 1.5KE250A only if validation confirms >600 W surge exposure; otherwise P6KE250A-E3/54 provides optimal cost-performance balance for standard automotive Grade 3 compliance. |
Compared with SMBJ250A and 1.5KE250A, P6KE250A-E3/54 offers the most cost-effective AEC-Q101-qualified solution for DO-15-restricted layouts requiring precise 600 W surge handling - balancing thermal performance, footprint compatibility, and qualification rigor without over-engineering.

FAQ
What is the maximum clamping voltage of the P6KE250A-E3/54 under standard test conditions?
The P6KE250A-E3/54 has a maximum clamping voltage (VC) of 344 V when subjected to a 10/1000 μs waveform peak pulse current of 1.7 A. This value is measured per JEDEC standards and defines the highest voltage the protected circuit will experience during a specified transient event - critical for ensuring downstream ICs remain within their absolute maximum ratings. The P6KE250A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE250A-E3/54 suitable for automotive applications?
Yes, the P6KE250A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics. Its DO-15 package, -55 °C to +175 °C operating junction range, and 600 W surge capability meet ISO 16750-2 and ISO 7637-2 requirements for load dump and coupled transient immunity. The E3 suffix confirms RoHS compliance and whisker testing to JESD 201 Class 1A - making P6KE250A-E3/54 appropriate for under-hood and cabin modules.
How does the P6KE250A-E3/54 differ from bidirectional TVS diodes like P6KE250CA?
The P6KE250A-E3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6KE250CA is bidirectional with no polarity marking and symmetric clamping in both directions. Unidirectional operation allows P6KE250A-E3/54 to provide lower leakage (<1 μA at 214 V) and tighter VBR tolerance, ideal for DC rail protection. Bidirectional variants are used for AC lines or differential signal pairs - so P6KE250A-E3/54 must not be substituted for P6KE250CA without verifying circuit polarity and transient directionality.
What is the thermal resistance specification for the P6KE250A-E3/54, and why does it matter?
The P6KE250A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt of dissipated power raises the junction temperature 20 °C above the lead temperature. This parameter is essential for calculating safe surge repetition rates and verifying thermal survival during multiple transients - especially in sealed enclosures where ambient temperature exceeds 75 °C. Accurate RθJL enables reliable lifetime prediction without overdesigning heatsinks, directly impacting P6KE250A-E3/54 deployment in thermally constrained modules.
Can the P6KE250A-E3/54 be used in place of older P6KE250A variants without design changes?
Yes, the P6KE250A-E3/54 is a direct replacement for legacy P6KE250A versions with identical electrical specifications, DO-15 mechanical dimensions, and pinout. The "E3" suffix denotes RoHS compliance and JESD 201 Class 1A whisker resistance, while "/54" indicates packaging in 13-inch paper tape and reel (4000 pcs). No PCB layout, schematic, or thermal design modifications are needed - the P6KE250A-E3/54 maintains full functional and mechanical compatibility with prior P6KE250A builds.
