Product details
Overview
P4KE150A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 150 V breakdown voltage (VBR min/max = 143–158 V), 128 V stand-off voltage (VWM), 207 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 μs), and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the P4KE150A-E3/54 datasheet, P4KE150A-E3/54 pinout, P4KE150A-E3/54 application, or P4KE150A-E3/54 equivalent, this device is selected for robust overvoltage protection in automotive power rails, industrial sensor interfaces, and DC supply inputs where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The P4KE150A-E3/54 uses a glass-passivated silicon junction to achieve stable avalanche breakdown with tight VBR tolerance (±5 % at IT = 1.0 mA). Its unidirectional polarity-marked by cathode band-enables integration into DC-biased circuits without reverse conduction during normal operation.
Clamping performance is defined by VC = 207 V at IPPM = 207 A (10/1000 μs), yielding a clamping ratio of 1.38×VWM, while thermal resistance RθJL = 66 °C/W supports reliable power dissipation under repetitive surge conditions up to 0.01 % duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at IT = 1.0 mA - ensures consistent avalanche initiation across production lots |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 207 V at 207 A (10/1000 μs) - defines worst-case clamped voltage seen by protected circuitry |
| PPPM | 400 W - peak transient energy absorption capability per single pulse |
| IFSM | 40 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction events |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and high-temp industrial environments |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body. Leads solderable per J-STD-002 and JESD 22-B102; qualified to JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during forward surge events (e.g., reverse polarity misconnection) |
| Cathode | Avalanche clamping terminal | Connected to higher-potential side; initiates controlled breakdown when reverse voltage exceeds VWM |
Key Features

| AEC-Q101 qualified (E3 suffix) | Validated for automotive powertrain and body electronics applications requiring zero defect rates |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a) |
| UL 94 V-0 compliant molding | Meets flammability safety requirements for enclosed industrial and automotive enclosures |

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, 1.5× smaller footprint, 600 W PPPM, same VBR/VWM specs | Higher board density required; better suited for space-constrained consumer PCBs | Select SMBJ150A when layout area is limited and higher surge margin is needed |
| 1.5KE150A | Same DO-41 package but 1500 W PPPM, higher IPPM (630 A), larger junction area | Used in heavy-duty industrial motor drives where multi-kA surge exposure occurs | Choose 1.5KE150A for applications demanding >5× the surge energy handling of P4KE150A-E3/54 |
Compared with SMBJ150A and 1.5KE150A, the P4KE150A-E3/54 delivers optimal balance of cost, proven automotive qualification (AEC-Q101), and standardized DO-41 through-hole assembly compatibility-making it preferred for legacy industrial controls and automotive modules where reworkability and thermal mass matter.

FAQ
What is the clamping voltage of the P4KE150A-E3/54 under maximum rated surge current?
The P4KE150A-E3/54 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 207 A using the standard 10/1000 μs waveform. This value is measured at the instant the current reaches its peak and reflects the upper limit of voltage imposed on the protected circuit during a worst-case transient event. The P4KE150A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P4KE150A-E3/54 suitable for automotive applications?
Yes, the P4KE150A-E3/54 is AEC-Q101 qualified (as indicated by the "E3" suffix), making it suitable for automotive applications including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and compliance with JESD 201 Class 1A whisker testing confirm its suitability for under-hood and chassis-mounted systems where thermal stress and long-term reliability are critical. The P4KE150A-E3/54 meets these requirements without derating.
How does the P4KE150A-E3/54 differ from bidirectional TVS diodes like P4KE150CA?
The P4KE150A-E3/54 is unidirectional and features a cathode band marking; it conducts only in reverse bias above VWM and blocks forward current until ~3.5 V. In contrast, P4KE150CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. The P4KE150A-E3/54 is intended for DC-biased lines (e.g., 12 V power rails), whereas P4KE150CA suits AC-coupled or floating signal paths. Their VBR and VC values differ accordingly.
What is the maximum steady-state power dissipation of the P4KE150A-E3/54?
The P4KE150A-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. This rating assumes ideal thermal conduction and must be derated linearly above 25 °C ambient per the published derating curve (Fig. 5). For typical PCB mounting, actual usable power is limited by trace copper area and layer count-not the P4KE150A-E3/54's intrinsic capability.
Can the P4KE150A-E3/54 be used in parallel for higher surge current handling?
No, the P4KE150A-E3/54 should not be operated in parallel without external balancing resistors due to manufacturing variations in VBR (±5 % tolerance), which cause uneven current sharing during transients. Uneven distribution risks thermal runaway in one device, leading to premature failure. For higher surge ratings, select a single higher-rated device such as 1.5KE150A instead of paralleling P4KE150A-E3/54 units.
