Product details
Overview
P4KE150CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 128 V standoff voltage (VWM), 143–158 V breakdown range (VBR) at 1 mA test current, 207 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the P4KE150CA-E3/54 datasheet, P4KE150CA-E3/54 pinout, P4KE150CA-E3/54 application, or P4KE150CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for transient energy dissipation in space-constrained PCB layouts.
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche junction structure. Its bidirectional symmetry enables suppression of both positive and negative transients without polarity sensitivity, and its glass-passivated chip ensures stable breakdown characteristics under repetitive surge stress.
The 10/1000 μs waveform rating reflects standardized lightning/surge immunity testing per REA definitions. Clamping voltage (VC = 207 V max at IPPM) is guaranteed across temperature (−55 °C to +175 °C), and thermal derating follows a linear curve above TA = 25 °C per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 207 V max at 207 A - Peak voltage seen by protected circuit during full-rated surge; determines downstream component stress |
| PPPM (Peak Pulse Power) | 400 W with 10/1000 μs waveform - Standardized surge energy handling capacity; validated at 0.01% duty cycle |
| RθJL (Junction-to-Lead Thermal Resistance) | 66 °C/W - Enables thermal design of lead-mounted PCB layout; critical for sustained surge repetition |
| TJ Max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments |

IC Role / Device Role / Timing Role: Clamp device placed after rectification but before LDO regulators, limiting voltage spikes to safe levels. Use Value: Eliminates need for oversized output capacitors or redundant regulation stages while meeting UL 62368-1 transient withstand requirements. |
Use Scenario: Primary protection for Ethernet PHYs and DSL line drivers connected to outside plant wiring subject to induced lightning surges. IC Role / Device Role / Timing Role: First-stage surge absorber mounted at connector entry point, diverting >1 kV transients to chassis ground. Use Value: Extends mean time between failures (MTBF) of telecom infrastructure by reducing cumulative degradation of sensitive analog front-end components. |
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 | Surface-mount SMB package; same VWM/VBR/VC ratings; lower RθJA (50 °C/W vs. 100 °C/W) | Better suited for high-density SMT layouts; requires reflow profile validation instead of wave soldering | Select when board space is constrained and thermal management uses copper pour rather than lead conduction |
| 1.5KE150CA | Higher PPPM (1500 W); larger DO-201AE package; higher IPPM (312 A); same VWM/VBR/VC | Used where single-event surge energy exceeds 400 W, e.g., AC mains input stages or motor drive feedback lines | Choose only if system-level surge testing requires >400 W margin; otherwise P4KE150CA-E3/54 offers optimal cost-size-performance balance |
Compared with SMBJ150CA and 1.5KE150CA, the P4KE150CA-E3/54 delivers verified AEC-Q101 qualification in a through-hole DO-41 form factor ideal for prototyping, service replacement, and legacy industrial designs requiring manual assembly or wave soldering compatibility.

FAQ
What is the clamping voltage of the P4KE150CA-E3/54 under full-rated surge conditions?
The P4KE150CA-E3/54 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 207 A with a 10/1000 μs waveform. This value is measured at the device terminals and represents the highest voltage imposed on the protected circuit during worst-case transient events, ensuring downstream ICs remain within safe operating limits.
Is the P4KE150CA-E3/54 suitable for automotive applications?
Yes, the P4KE150CA-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, ADAS sensors, and body electronics. Its −55 °C to +175 °C operating junction temperature range and validated reliability under temperature cycling, HTRB, and ESD stress make it appropriate for under-hood and cabin-mounted systems.
How does the bidirectional configuration of the P4KE150CA-E3/54 affect its circuit implementation?
The P4KE150CA-E3/54 has no polarity marking and functions identically in both directions, allowing either lead to connect to signal or ground. This simplifies layout, eliminates orientation errors during assembly, and enables symmetric protection of AC-coupled or differential lines such as CAN bus or RS-485 without external diode pairing.
What is the thermal resistance specification for the P4KE150CA-E3/54, and why does it matter?
The P4KE150CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This parameter directly impacts how effectively surge energy is conducted away from the junction through the leads into the PCB copper. Lower RθJL values improve survivability during repetitive surges and inform trace width and pad design for thermal relief.
Can the P4KE150CA-E3/54 replace unidirectional TVS diodes in existing designs?
No - the P4KE150CA-E3/54 is strictly bidirectional and lacks cathode/anode polarity. Replacing a unidirectional TVS (e.g., P4KE150A) with P4KE150CA-E3/54 may cause unintended forward conduction in DC-biased circuits. Use only where bidirectional clamping is required, such as AC signal lines or floating grounds; verify system-level polarity constraints before substitution.
