Product details
Overview
P6KE150A-E3/54 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, 600 W peak pulse power rating (10/1000 μs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply input stages.
For engineers reviewing the P6KE150A-E3/54 datasheet, P6KE150A-E3/54 pinout, P6KE150A-E3/54 application, or P6KE150A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101 qualification status for automotive-grade design validation.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance. Its 600 W peak pulse power rating is defined per 10/1000 μs waveform with 0.01 % duty cycle, and clamping voltage remains stable up to 175 °C junction temperature.
The device exhibits a positive temperature coefficient of breakdown voltage (+0.108 %/°C), enabling predictable voltage shift under thermal stress. With 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient resistance, it supports reliable power dissipation up to 5.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at IT = 1.0 mA - defines minimum guaranteed clamping onset threshold under standardized test current |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA; sets safe DC operating margin |
| VC @ IPPM | 207 V at 2.9 A - maximum clamped voltage during 10/1000 μs transient; determines protected circuit's worst-case overvoltage exposure |
| PPPM | 600 W - peak pulse power handling capability; enables robust protection against lightning-induced surges and inductive switching spikes |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine); supports single-event fault clearing without catastrophic failure |
| TJ max. | +175 °C - extended junction temperature rating allows use in under-hood automotive environments and high-power industrial enclosures |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enables efficient heat transfer to PCB copper pour or heatsinked leads |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during reverse-transient suppression |
| Cathode | Reverse-biased terminal | Connected to protected line (e.g., 12 V rail); blocks normal operation but avalanches during overvoltage to clamp energy into anode path |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable long-term reliability under repeated surge stress without degradation |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics per stress test requirements including HTOL, TC, UHAST, and ESD - suitable for engine control and body modules |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity when properly laid out with low-inductance PCB routing |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during transient events, reducing stress on downstream MOSFETs, regulators, and microcontrollers |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Ensures lead finish integrity in high-vibration environments and eliminates tin whisker risk in long-life automotive applications |

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 | DO-214AA package, 600 W rating, VBR = 143–158 V, VC = 243 V @ 2.5 A - higher clamping voltage, surface-mount only | Requires SMT layout; less suited for through-hole high-current chassis connections or manual repair | Select SMBJ150A only when board space constraints mandate SMT and clamping margin permits 36 V higher VC. |
| 1.5KE150A | DO-201AD package, same VBR/VC specs, 1500 W peak power - larger case, higher thermal mass, 1.5× footprint | Better thermal endurance for repetitive surges; not drop-in compatible due to longer lead spacing and higher weight | Choose 1.5KE150A where sustained surge duty cycles exceed 0.01 % or where legacy DO-201AD sockets exist. |
Compared with SMBJ150A and 1.5KE150A, P6KE150A-E3/54 offers optimal balance of axial-leaded mechanical robustness, AEC-Q101 qualification, and compact DO-15 footprint - making it preferred for cost-sensitive, high-volume automotive and industrial through-hole designs requiring validated reliability.

FAQ
What is the maximum clamping voltage of P6KE150A-E3/54 under standard surge conditions?
The P6KE150A-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 10/1000 μs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream components during transient suppression. The P6KE150A-E3/54 maintains this clamping performance across its full operating temperature range up to +175 °C junction temperature.
Is P6KE150A-E3/54 qualified for automotive applications?
Yes, the P6KE150A-E3/54 is AEC-Q101 qualified per Vishay documentation (Document Number 88369, Revision 27-Sep-2021). The "E3" suffix denotes RoHS-compliant commercial grade with JESD 201 Class 1A whisker testing, and the HE3 variant adds full AEC-Q101 qualification. Engineers deploying P6KE150A-E3/54 in engine control, body electronics, or ADAS modules can rely on its validated stress-test performance.
How does the thermal resistance of P6KE150A-E3/54 affect PCB layout decisions?
The P6KE150A-E3/54 has RθJL = 20 °C/W and RθJA = 75 °C/W, meaning effective heat removal depends heavily on copper pour area connected to its leads. For continuous 5.0 W dissipation, PCB land patterns must provide ≥100 mm² of 2-oz copper per lead. The P6KE150A-E3/54 benefits from short, wide traces and thermal vias to inner ground planes - especially critical in automotive under-hood applications where ambient temperatures exceed 85 °C.
Can P6KE150A-E3/54 be used in bidirectional configurations?
No - P6KE150A-E3/54 is strictly unidirectional, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE150CA). Using P6KE150A-E3/54 in AC or dual-polarity circuits will result in forward conduction during negative half-cycles, causing failure. Always verify polarity marking and select P6KE150CA only when symmetrical clamping in both directions is required.
What is the leakage current specification for P6KE150A-E3/54 at its working voltage?
At its maximum steady-state reverse voltage (VWM = 128 V), the P6KE150A-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage ensures minimal power loss in always-on systems and prevents drift in precision analog circuits powered from the same rail. The P6KE150A-E3/54 maintains leakage below 5.0 μA even at +125 °C ambient, supporting high-reliability industrial deployments.
