Product details
Overview
P6KE250A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 214 V stand-off 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.
For engineers reviewing the P6KE250A-E3/73 datasheet, P6KE250A-E3/73 pinout, P6KE250A-E3/73 application, or P6KE250A-E3/73 equivalent, key selection criteria include clamping performance under 1.7 A surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, AEC-Q101 qualification status, and compatibility with 275 °C solder dip per JESD 22-B106.
Technical Context
The P6KE250A-E3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning surges. Its unidirectional configuration provides cathode-marked polarity and forward conduction capability up to 100 A IFSM (8.3 ms half-sine).
Clamping behavior is defined by a maximum VC of 344 V at IPPM = 1.7 A (10/1000 μs), with temperature coefficient of VBR at +0.110 %/°C. It exhibits low incremental surge resistance and is rated for continuous power dissipation of 5.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 214 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin. |
| VBR (Breakdown Voltage) | 237–263 V at IT = 1 mA - Avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 344 V at IPPM = 1.7 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge. |
| PPPM (Peak Pulse Power) | 600 W - Sustains short-duration transients without failure; validated per Fig. 1 derating curve. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - Withstands repetitive inrush or fault currents in power supply inputs. |
| TJ max. | +175 °C - Enables operation in high-temperature environments including under-hood automotive zones. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance supports efficient heat transfer to PCB copper or heatsink. |

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; lower RθJA (50 °C/W vs. 75 °C/W); same VWM/VBR/VC ratings. | Better suited for surface-mount layouts with limited board space; requires rework for through-hole replacement. | Select SMBJ250A when automated SMT assembly is preferred and thermal pad area is available. |
| 1.5KE250A | Same DO-15 package but 1500 W PPPM rating; higher IPPM (3.4 A); larger junction capacitance (≈150 pF vs. ~50 pF). | Higher surge margin for infrequent extreme events; increased capacitive loading may affect high-speed signal integrity. | Choose 1.5KE250A where legacy 1.5 kW surge compliance is mandated and bandwidth impact is acceptable. |
Compared with SMBJ250A and 1.5KE250A, P6KE250A-E3/73 offers optimal balance of through-hole manufacturability, 600 W robustness, and minimal parasitic capacitance-ideal for cost-sensitive 24–48 V industrial and automotive power interfaces where DO-15 mechanical retention is required.

FAQ
What is the clamping voltage of P6KE250A-E3/73 at its rated peak pulse current?
The P6KE250A-E3/73 has a maximum clamping voltage (VC) of 344 V when subjected to its specified peak pulse current (IPPM) of 1.7 A using the standard 10/1000 μs waveform. This value is measured under controlled conditions per Figure 1 in the Vishay datasheet 88369 and reflects worst-case voltage exposure to downstream circuitry during surge events.
Is P6KE250A-E3/73 suitable for automotive applications?
Yes, P6KE250A-E3/73 is AEC-Q101 qualified per the HE3 suffix variant; however, the E3/73 variant is RoHS-compliant commercial grade. For automotive use, confirm with Vishay documentation whether the specific P6KE250A-E3/73 lot is certified under AEC-Q101-some E3 batches are qualified, but full qualification requires HE3 marking. Always verify qualification status via traceable certificate of compliance.
What does the "-E3/73" suffix indicate in P6KE250A-E3/73?
The "-E3" denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/73" specifies packaging in 73-inch tape-and-reel format (4000 pcs/reel). This differs from /54 (13-inch reel) and confirms compliance with lead-free assembly requirements and standardized logistics handling for automated placement.
How does P6KE250A-E3/73 compare to bidirectional variants like P6KE250CA?
P6KE250A-E3/73 is unidirectional with cathode marking and forward conduction capability (VF = 5.0 V at 50 A), whereas P6KE250CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Use P6KE250A-E3/73 for DC rail protection where polarity is fixed; choose P6KE250CA only for AC-coupled or floating signal lines requiring dual-direction clamping.
What is the maximum operating temperature for P6KE250A-E3/73?
The P6KE250A-E3/73 has a maximum junction temperature (TJ max.) of +175 °C and an operating junction/storage temperature range of –55 °C to +175 °C. This allows deployment in under-hood automotive, industrial motor drives, and outdoor telecom enclosures where ambient temperatures exceed 105 °C, provided thermal design accounts for RθJL = 20 °C/W and power derating per Figure 5.
