Product details
Overview
P6KE150C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 150V nominal standoff voltage, 215V maximum clamping voltage at 2.9A peak pulse current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive lighting control modules to safeguard CAN transceivers against load dump and EFT events.
For engineers reviewing the P6KE150C datasheet, P6KE150C pinout, P6KE150C application, or P6KE150C equivalent, key selection criteria include verified bidirectional clamping performance, AEC-Q101 qualification status, junction temperature derating above 25°C, and compatibility with 10/1000μs surge waveforms per IEC 61000-4-5 Level 4.
Technical Context
The P6KE150C operates as a silicon avalanche diode with symmetrical breakdown in both polarities, enabling bidirectional transient suppression without polarity sensitivity. Its low dynamic impedance ensures rapid voltage clamping during fast-rising transients, while its 175°C maximum junction temperature supports operation in under-hood automotive environments.
Clamping response is characterized by sub-nanosecond turn-on (≤1.0ps unidirectional, ≤5.0ns bidirectional), and it maintains <1μA reverse leakage at 121V standoff - critical for low-power sensor interfaces. The device complies with UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.

| Automotive CAN Bus Interface | Smart Building Sensor Node |
Use Scenario: Transient protection on CAN_H and CAN_L lines in gateway ECUs where ESD and coupled noise threaten physical layer transceivers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed differential across bus lines to suppress common-mode surges without distorting signal integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA (Bourns) | Same 150V VWM, 215V VC, but SMB package (surface-mount); 600W rating at 10/1000μs | Requires PCB redesign for SMT vs. through-hole; better thermal dissipation in compact layouts | Select when board space is constrained and reflow assembly is used |
| 1.5KE150CA (ON Semiconductor) | Identical electrical specs (150V VWM, 215V VC, 600W), DO-204AC package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial use only | Select for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with P6KE150C, SMBJ150CA offers surface-mount compatibility at the expense of through-hole assembly flexibility, while 1.5KE150CA provides identical protection performance without automotive qualification - making P6KE150C the preferred choice for AEC-Q101-compliant vehicle subsystems.

FAQ
What is the clamping voltage of P6KE150C at its rated peak pulse current?
The P6KE150C has a maximum clamping voltage (VC) of 215 V at 2.9 A peak pulse current (IPP), measured under the standard 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is confirmed per ANSI/IEEE C62.35 test conditions. The P6KE150C maintains this clamping performance across its full operating temperature range.
Is P6KE150C unidirectional or bidirectional?
P6KE150C is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity dependence. Its marking does not include a cathode band, and its electrical specifications - including identical VBR min/max and VC values in both directions - confirm true bidirectional behavior. This makes the P6KE150C suitable for protecting AC-coupled lines, differential buses like CAN, and floating power domains.
Does P6KE150C meet AEC-Q101 qualification?
The base P6KE150C is not AEC-Q101 qualified; however, the AEC-Q101-compliant variant is designated P6KE150CH (with 'H' suffix). Per Taiwan Semiconductor's ordering information, all P6KExH parts - including P6KE150CH - undergo full AEC-Q101 stress testing (HTGB, TCT, H3TRB, etc.) and are approved for automotive under-hood applications. Always verify the 'H' suffix when specifying for automotive programs.
What is the maximum junction temperature rating for P6KE150C?
The P6KE150C has a maximum junction temperature (TJ) rating of +175°C, with a minimum of −55°C - enabling reliable operation in high-ambient environments such as engine compartments and industrial motor drives. Derating of peak pulse power begins above TA = 25°C per the published pulse derating curve (Fig.2), and thermal design must account for lead length and PCB copper area per the datasheet's PD = 5 W specification at 75°C ambient.
How does P6KE150C compare to P6KE150A in terms of electrical performance?
P6KE150C and P6KE150A differ in breakdown voltage tolerance: P6KE150C has a VBR range of 135–165 V (±10%), while P6KE150A tightens this to 143–158 V (±5%). Both share identical VWM (121 V), VC (215 V), and PPK (600 W). The tighter VBR spread of P6KE150A improves consistency in clamping onset across production lots - useful in precision protection schemes - whereas P6KE150C offers broader interchangeability in less sensitive applications.
