Product details
Overview
P6KE150CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features a 150 V breakdown voltage (VBR min/max = 143 V / 158 V), 128 V standoff voltage (VWM), 207 V maximum clamping voltage at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive power distribution systems.
For engineers reviewing the P6KE150CA-E3/54 datasheet, P6KE150CA-E3/54 pinout, P6KE150CA-E3/54 application, or P6KE150CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at VWM), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped shunt protector: during overvoltage events exceeding VWM = 128 V, it avalanches symmetrically in both directions to limit transient voltage to ≤207 V at IPPM = 2.9 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while thermal resistance RθJA = 75 °C/W supports operation up to 175 °C junction temperature.
The P6KE150CA-E3/54 complies with IEC 61000-4-2/4-4/4-5 surge immunity standards when applied with proper PCB layout. Its unmarked bidirectional polarity eliminates orientation concerns during placement, and its 0.432 g unit weight and DO-15 footprint align with space-constrained industrial and automotive control modules requiring robust ESD and lightning surge protection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | DO-214AA package; 150 V VWM, 243 V VC @ 2.5 A; lower 600 W rating but higher IPPM density due to surface-mount footprint. | Preferred for automated SMT assembly; unsuitable for through-hole legacy designs or high-vibration environments requiring axial lead retention. | Select SMBJ150CA only if board space is constrained and reflow profile supports DO-214AA thermal mass. |
| 1.5KE150CA | Same DO-15 package; 150 V VWM, 243 V VC @ 6.1 A; 1500 W peak power rating but larger physical size and higher leakage (5.0 μA). | Better suited for high-energy surge environments (e.g., outdoor telecom cabinets); over-spec'd for typical automotive interior modules. | Choose 1.5KE150CA only when system-level testing confirms need for >600 W clamping energy absorption. |
Compared with SMBJ150CA and 1.5KE150CA, P6KE150CA-E3/54 offers optimal balance of DO-15 mechanical robustness, 600 W surge handling, and <1.0 μA leakage - making it the preferred choice for cost-sensitive, vibration-prone automotive and industrial through-hole applications where precise clamping voltage and low standby current are critical.

FAQ
What is the clamping voltage of P6KE150CA-E3/54 at its rated peak pulse current?
The P6KE150CA-E3/54 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 2.9 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuits during surge events. The P6KE150CA-E3/54 maintains this clamping performance across its full operating temperature range of −55 °C to +175 °C.
Is P6KE150CA-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
P6KE150CA-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial grade construction and JESD 201 Class 1A whisker resistance - but it is not AEC-Q101 qualified. For automotive applications requiring formal AEC-Q101 certification, the HE3-suffixed variant (e.g., P6KE150CAHE3/54) must be selected. The P6KE150CA-E3/54 remains widely used in non-safety-critical automotive subsystems where commercial-grade reliability is acceptable.
How does the bidirectional nature of P6KE150CA-E3/54 affect PCB layout and mounting?
The P6KE150CA-E3/54 has no polarity marking and functions identically in both directions, so PCB layout requires no anode/cathode orientation check during placement. Its DO-15 axial package uses two identical leads, enabling direct replacement of failed units without verifying orientation. This simplifies manual assembly, rework, and field repair - especially valuable in high-mix manufacturing environments where P6KE150CA-E3/54 serves alongside unidirectional variants like P6KE150A.
What is the maximum reverse leakage current of P6KE150CA-E3/54 at its standoff voltage?
At its 128 V standoff voltage (VWM), the P6KE150CA-E3/54 exhibits a maximum reverse leakage current (IDRM) of 1.0 μA at 25 °C, per Vishay specification table on page 2 of document 88369. This ultra-low leakage ensures minimal power loss and avoids loading effects on high-impedance sensor outputs or precision reference lines where even nanoamp-level currents could induce measurement errors.
Can P6KE150CA-E3/54 be used in parallel to increase surge current handling?
No - P6KE150CA-E3/54 should not be paralleled to increase surge current capacity. Due to inherent VBR tolerance (143–158 V), mismatched avalanche onset causes uneven current sharing, leading to premature failure of the lower-breakdown unit. For higher IPPM requirements, select a single higher-rated device such as 1.5KE150CA (6.1 A) or verify coordinated clamping with external impedance balancing per Vishay application note AN8001.
