Product details
Overview
P4SMA150CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 150 V standoff voltage (VWM), 165 V minimum breakdown voltage (VBR), 207 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom systems.
For engineers reviewing the P4SMA150CA-E3/61 datasheet, P4SMA150CA-E3/61 pinout, P4SMA150CA-E3/61 application, or P4SMA150CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, 150 V working voltage, 207 A surge handling at 10/1000 µs, low clamping voltage of 207 V, and AEC-Q101 qualification availability in automotive-grade variants.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low incremental surge resistance minimizes voltage overshoot during ESD or lightning-induced surges.
The device is rated for 400 W peak pulse power (derated to 300 W above 91 V), with thermal resistance RθJA = 120 °C/W and maximum junction temperature of 150 °C. It meets J-STD-020 MSL Level 1 and supports automated SMT placement due to its low-profile SMA package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for protected circuitry. |
| VBR (Breakdown Voltage) | 165 V min - Voltage at which device enters avalanche conduction; ensures reliable turn-on before damage threshold. |
| VC (Clamping Voltage) | 207 V at IPPM - Peak voltage seen by downstream circuit during 207 A transient; critical for IC-level protection margin. |
| IPPM (Peak Pulse Current) | 207 A - Maximum non-repetitive surge current it can safely divert using 10/1000 µs waveform. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy-handling capacity under standard test condition; derates to 300 W above 91 V. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Negligible leakage current preserves signal integrity and power efficiency in standby. |
| TJ max | 150 °C - Maximum junction temperature; enables operation in high-ambient industrial environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Not functional in bidirectional clamping mode; symmetrical terminals enable polarity-agnostic placement. |
| Cathode | Current exit terminal in forward bias | Not functional in bidirectional clamping mode; no marking on bidirectional devices per spec. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same VWM (150 V) and VC (243 V), but SMB package (DO-214AA); 600 W PPPM rating. | Higher power handling but larger footprint; requires PCB layout change. | Select when higher surge margin is needed and board space allows SMB footprint. |
| 1.5SMC150CA | Same VWM/VC specs, but SMC package (DO-214AB); 1500 W PPPM, higher IPPM (312 A). | Designed for primary-side AC line protection; not optimized for signal-line placement density. | Choose for front-end AC input stages where space and thermal mass support larger SMC outline. |
Compared with P4SMA150CA-E3/61, SMBJ150CA offers higher surge rating in a slightly larger package, while 1.5SMC150CA delivers triple the power handling in a significantly larger outline - making P4SMA150CA-E3/61 optimal for space-constrained secondary-side or signal-line protection where 400 W suffices.

FAQ
What is the clamping voltage of P4SMA150CA-E3/61 at its rated peak pulse current?
The clamping voltage (VC) of P4SMA150CA-E3/61 is 207 V when subjected to its maximum peak pulse current (IPPM) of 207 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and reflects the maximum voltage imposed on protected circuitry during worst-case surge events. The P4SMA150CA-E3/61 maintains this clamping performance bidirectionally, ensuring consistent protection regardless of transient polarity.
Is P4SMA150CA-E3/61 suitable for automotive applications?
P4SMA150CA-E3/61 itself is commercial-grade and RoHS-compliant, but Vishay offers an AEC-Q101-qualified version under the ordering code P4SMA150CAHE3_A. That variant shares identical electrical specs and SMA packaging while meeting automotive reliability requirements including temperature cycling, humidity testing, and accelerated life validation. For automotive designs, specify the HE3 suffix variant rather than P4SMA150CA-E3/61 unless only commercial-grade qualification is required.
How does the bidirectional configuration of P4SMA150CA-E3/61 affect its PCB layout?
The bidirectional nature of P4SMA150CA-E3/61 eliminates polarity marking - there is no cathode band or orientation requirement during placement. This simplifies PCB layout and assembly, especially for differential or floating signal lines like RS-485, CAN, or Ethernet pairs. Unlike unidirectional TVS diodes, P4SMA150CA-E3/61 can be placed without regard to signal direction, reducing design risk and enabling reuse across multiple interface types without footprint changes.
What is the maximum operating temperature for P4SMA150CA-E3/61?
P4SMA150CA-E3/61 has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. Its thermal resistance from junction to ambient (RθJA) is 120 °C/W under standard mounting conditions (0.2" × 0.2" copper pads). Derating curves in Figure 2 of the datasheet show usable power dissipation decreases linearly above 25 °C ambient, supporting reliable operation in enclosed industrial enclosures or under-hood automotive locations when thermally managed.
Does P4SMA150CA-E3/61 meet any industry safety or flammability standards?
Yes - P4SMA150CA-E3/61's SMA (DO-214AC) package uses molding compound compliant with UL 94 V-0 flammability rating, and the device carries Underwriters Laboratory Recognition (QVGQ2) under UL 497B for protector classification. It is also rated per ANSI/IEEE C62.35 for transient voltage protection devices. These certifications validate its suitability for end-equipment requiring safety agency approval, including industrial controls, telecom infrastructure, and consumer power supplies.
