Product details
Overview
P6KE150A-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 150 V breakdown voltage (VBR = 143–158 V at 1.0 mA), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, microcontrollers, and sensor interfaces against inductive switching transients in industrial motor drives.
For engineers reviewing the P6KE150A-E3/73 datasheet, P6KE150A-E3/73 pinout, P6KE150A-E3/73 application, or P6KE150A-E3/73 equivalent, key selection criteria include standoff voltage (VWM = 128 V), low leakage (<1.0 µA), AEC-Q101 qualification status (E3 suffix denotes commercial grade; HE3 required for automotive), thermal resistance (RθJA = 75 °C/W), and DO-15 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤207 V at 2.9 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns).
Designed for single-pulse surge suppression per IEC 61000-4-5 Level 3 (1 kV/2 Ω), it supports repetitive surges at 0.01% duty cycle and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and derating above TA = 25 °C per Figure 2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Same VBR range (143–158 V) but SMC (DO-214AB) surface-mount package; 600 W rating; lower RθJA (50 °C/W) | Requires PCB redesign for SMT layout; better thermal performance in dense layouts | Select SMBJ150A for new designs prioritizing board space and thermal efficiency over through-hole serviceability |
| 1.5KE150A | Same DO-15 package and electrical specs, but 1.5 kW peak power rating (10/1000 µs); larger die size; higher IPPM (9.8 A) | Overqualified for 600 W needs; higher cost and capacitance; suitable for harsher surge environments | Choose 1.5KE150A only if system-level testing requires >600 W margin or legacy 1.5KE footprint reuse |
Compared with SMBJ150A, P6KE150A-E3/73 offers direct DO-15 through-hole compatibility and lower cost for legacy repairs; versus 1.5KE150A, it delivers optimal cost-performance balance for standard 600 W IEC-compliant protection without over-engineering.

FAQ
What is the standoff voltage rating of the P6KE150A-E3/73?
The P6KE150A-E3/73 has a maximum stand-off voltage (VWM) of 128 V, meaning it remains in high-impedance blocking mode up to this DC or RMS voltage level while maintaining reverse leakage below 1.0 µA. This value ensures compatibility with 120 V AC-derived DC rails and 24–48 V industrial systems where sustained overvoltage must be avoided. The P6KE150A-E3/73 is therefore suited for primary-side clamping in such applications.
Is the P6KE150A-E3/73 suitable for automotive applications?
The P6KE150A-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction and not AEC-Q101 qualification. For automotive use, the HE3-suffixed variant (P6KE150AHE3/73) must be selected. The P6KE150A-E3/73 itself is appropriate for non-safety-critical industrial or consumer systems where AEC-Q101 is not mandated, but its electrical specs - including 175 °C TJ max and 100 A IFSM - remain identical to the qualified version.
What is the clamping voltage of the P6KE150A-E3/73 at its rated peak pulse current?
The P6KE150A-E3/73 exhibits a maximum clamping voltage (VC) of 207 V when subjected to its specified peak pulse current (IPPM) of 2.9 A under the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured per JEDEC standards. Designers must ensure downstream components tolerate this 207 V transient, confirming margin relative to their absolute maximum ratings. The P6KE150A-E3/73 achieves this with minimal voltage overshoot due to its fast <1 ns response.
How does the P6KE150A-E3/73 differ from the 1.5KE150A in practical design use?
The P6KE150A-E3/73 and 1.5KE150A share identical VBR (143–158 V), VWM (128 V), and DO-15 packaging, but the 1.5KE150A offers 1.5 kW peak pulse power (vs. 600 W) and higher IPPM (9.8 A). In practice, the P6KE150A-E3/73 is preferred for cost-sensitive, IEC 61000-4-5 Level 3-compliant designs where 600 W suffices, whereas the 1.5KE150A suits harsher environments like utility metering or railway systems. Both parts use the same footprint, but the P6KE150A-E3/73 reduces bill-of-materials cost without sacrificing core protection function.
What is the thermal resistance and maximum junction temperature of the P6KE150A-E3/73?
The P6KE150A-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ) of +175 °C. These values define its safe operating area under continuous power dissipation and transient overload. At 25 °C ambient, its 5.0 W steady-state power rating allows use in thermally constrained enclosures, while the 175 °C TJ max enables deployment in high-temperature industrial settings. Derating begins above 25 °C per Figure 2 in the Vishay datasheet 88369, and the P6KE150A-E3/73 maintains full surge capability within this envelope.
