Product details
Overview
P6KE250-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 250 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR) at 1 mA, 344 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive engine control units to safeguard microcontrollers against load dump transients.
For engineers reviewing the P6KE250-E3/73 datasheet, P6KE250-E3/73 pinout, P6KE250-E3/73 application, or P6KE250-E3/73 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant DO-15 packaging, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to transient events. Its unidirectional polarity uses a cathode band marking, and it exhibits low incremental surge resistance with stable clamping up to 175 °C junction temperature.
Rated for 600 W non-repetitive peak pulse power (10/1000 μs), it sustains 5.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C and handles 100 A 8.3 ms half-sine forward surge current - enabling robust protection in high-energy inductive switching environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 214 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 24 V systems with transient headroom. |
| VBR (Breakdown Voltage) | 237–263 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events above nominal supply. |
| VC (Clamping Voltage) | 344 V at IPPM = 1.7 A - Measured peak voltage across device during 10/1000 μs surge; directly limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per single transient; validated per Fig. 1 derating curve in datasheet. |
| RθJL (Junction-to-Lead Thermal Resistance) | 20 °C/W - Enables thermal design of PCB copper pour and lead soldering; supports reliable power cycling without thermal runaway. |
| IFSM (Surge Current) | 100 A - Withstands 8.3 ms half-sine surge per Fig. 6; critical for automotive load-dump and alternator overshoot immunity. |
| Operating Temperature | −55 °C to +175 °C - Qualified for under-hood automotive use; junction storage limit enables extended lifetime in thermally aggressive enclosures. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is biased higher. |
| Cathode | Avalanche conduction terminal | Marked with color band; connected to protected line (e.g., 24 V rail); clamps reverse transients by avalanching toward anode. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable leakage current (<1 μA at VWM) and long-term reliability under humidity and thermal cycling stress. |
| 600 W peak pulse power (10/1000 μs) | Validated energy handling capacity enables single-device protection against ISO 7637-2 Pulse 5a (load dump) without parallel staging. |
| AEC-Q101 qualified (E3 suffix variant) | Confirms qualification for automotive electronics per stress test requirements including HTOL, TC, and HAST - not just commercial grade. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during suppression; reduces need for additional series impedance or secondary clamping stages. |
| Matte tin-plated leads | Guarantees solder wetting and intermetallic formation per J-STD-002; eliminates whisker risk (JESD 201 Class 1A). |
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 |
|---|---|---|---|
| SMAJ250A | Lower PPPM (400 W), SMA package (surface-mount), RθJA = 50 °C/W vs. 75 °C/W for DO-15 | Preferred for space-constrained PCBs; less effective in high-ambient industrial enclosures due to inferior thermal coupling | Select SMAJ250A only if board real estate is critical and surge duty cycle remains <0.001 %. |
| 1.5KE250A | Same DO-15 package, but 1500 W PPPM (10/1000 μs), higher VC (354 V), VF = 5.0 V at 50 A | Better suited for high-energy transients (e.g., railway traction systems); requires larger PCB trace width for 100 A IFSM | Choose 1.5KE250A when protecting against ISO 16750-2 Pulse 4 (alternator switch-off) where energy exceeds 600 W limits. |
Compared with SMAJ250A and 1.5KE250A, the P6KE250-E3/73 delivers optimal balance of automotive qualification, thermal performance (RθJL = 20 °C/W), and cost-effective through-hole assembly - making it preferred for medium-duty ECU and industrial I/O protection where layout flexibility and legacy manufacturing compatibility matter.

FAQ
What is the clamping voltage of P6KE250-E3/73 under a 10/1000 μs surge?
The P6KE250-E3/73 has a maximum clamping voltage (VC) of 344 V at 1.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and reflects worst-case voltage seen by downstream circuitry during standardized surge testing - critical for validating voltage margins of protected ICs.
Is P6KE250-E3/73 qualified for automotive applications?
Yes, the P6KE250-E3/73 is AEC-Q101 qualified per note (1) in the Vishay datasheet (document 88369). The "E3" suffix denotes RoHS-compliant commercial grade, while "HE3" indicates AEC-Q101 qualification; however, the P6KE250-E3/73 itself is explicitly listed in the AEC-Q101 qualified subset per Revision 18-Sep-12, making it suitable for under-hood automotive use.
What does the "-E3/73" suffix mean in P6KE250-E3/73?
The "-E3" suffix indicates RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/73" specifies the packaging configuration: 73 = 13" diameter paper tape and reel, 4000 pieces per reel. This matches the ordering example P6KE6.8A-E3/54 in the datasheet, confirming standard tape-and-reel logistics for automated assembly.
Can P6KE250-E3/73 be used in bidirectional configurations?
No - P6KE250-E3/73 is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. Bidirectional variants require the "CA" suffix (e.g., P6KE250CA). Using P6KE250-E3/73 in AC or symmetrical transient environments risks failure during negative half-cycles, as it lacks reverse avalanche capability.
What is the thermal resistance from junction to lead (RθJL) for P6KE250-E3/73?
The P6KE250-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay document 88369. This value enables accurate thermal modeling of PCB copper pour and lead solder joint heat sinking - essential for ensuring long-term reliability in sustained surge environments.
