Product details
Overview
P6KE250C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 250 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR) 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. It is used in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the P6KE250C-E3/73 datasheet, P6KE250C-E3/73 pinout, P6KE250C-E3/73 application, or P6KE250C-E3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 20 °C/W), bi-directional symmetry for AC-coupled lines, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P6KE250C-E3/73 operates as a voltage-clamped avalanche diode with symmetrical bi-directional conduction-no polarity marking required. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients without overshoot.
It is rated for 600 W peak pulse power (10/1000 µs), derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surge duty cycles up to 0.01 %. With a maximum junction temperature of 175 °C and thermal resistance of 20 °C/W (junction-to-lead), it sustains transient energy dissipation in compact DO-15 layouts without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 214 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 237–263 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 344 V at IPPM = 1.7 A - Peak voltage seen by protected circuit under worst-case 10/1000 µs surge; determines IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability for standardized surge waveforms; validates robustness vs. IEC 61000-4-5 Level 4. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Negligible standby current; avoids loading on high-impedance signal paths like sensor outputs. |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal shutdown. |
| RθJL | 20 °C/W - Low thermal resistance allows efficient heat transfer to PCB copper or lead frame; supports high-reliability mounting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA | Same VWM (214 V) and VC (344 V), but in SMB package (surface-mount); lower RθJA (50 °C/W vs. 75 °C/W), higher IPPM (1.8 A). | Requires PCB rework for SMT layout; better suited for space-constrained designs where thermal via use is feasible. | Select SMBJ250CA when board real estate is limited and automated assembly is preferred; verify pad thermal relief for 600 W pulse handling. |
| 1.5KE250CA | Same DO-15 package and electrical specs, but 1500 W peak power rating; larger die, higher VF (5.0 V), heavier weight (1.1 g vs. 0.432 g). | Over-specified for 600 W needs; introduces unnecessary cost and board stress in vibration-prone automotive mounts. | Choose 1.5KE250CA only if future design scaling to higher surge levels (e.g., ISO 7637-2 Pulse 5a) is anticipated; otherwise P6KE250C-E3/73 offers optimal cost-performance balance. |
Compared with SMBJ250CA and 1.5KE250CA, P6KE250C-E3/73 delivers precise 600 W surge capability in the proven DO-15 through-hole format, with verified thermal performance (RθJL = 20 °C/W) and commercial-grade cost efficiency-ideal for high-volume industrial and automotive aftermarket applications where reliability and manufacturability are prioritized.

FAQ
What is the polarity configuration of P6KE250C-E3/73?
P6KE250C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and no functional polarity-either lead may be connected to line or ground. This eliminates orientation errors during manual or automated assembly and simplifies layout for AC-coupled signals such as RS-485 or audio lines.
Does P6KE250C-E3/73 meet AEC-Q101 qualification?
No-P6KE250C-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial grade per JESD 201 Class 1A whisker testing. The AEC-Q101 qualified version is designated P6KE250CHE3/73 (HE3 suffix). Both share identical electrical parameters and DO-15 packaging, but only the HE3 variant undergoes extended temperature cycling, humidity bias, and mechanical shock testing required for automotive under-hood use.
What is the maximum clamping voltage of P6KE250C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE250C-E3/73 is 344 V, measured at a peak pulse current (IPPM) of 1.7 A with a 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and must be compared directly against the absolute maximum ratings of downstream ICs to ensure safe operation.
How does P6KE250C-E3/73 differ from P6KE250A-E3/73?
P6KE250C-E3/73 is bi-directional (denoted by 'C'), while P6KE250A-E3/73 is uni-directional ('A'). The bi-directional version has identical VWM (214 V), VBR (237–263 V), and VC (344 V) specs but conducts symmetrically-critical for protecting AC signals or differential buses. The uni-directional variant includes a cathode band and exhibits forward voltage (~5.0 V at 50 A), making it unsuitable for bidirectional line protection without additional circuitry.
What is the thermal resistance profile of P6KE250C-E3/73?
P6KE250C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. This means that with 600 W peak power applied for <1 ms, junction temperature rise remains manageable when leads are soldered to adequate copper area. For sustained surge repetition, thermal design must account for lead-frame conduction-not PCB traces-as the dominant heat path.
