Use Scenario: Guards microcontroller I/O and H-bridge gate drive signals against back-EMF from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Mounted directly at motor connector terminals to intercept transients before propagation into logic-level circuitry. Use Value: 85.0 V clamping voltage prevents latch-up in 5 V/3.3 V logic, while 150 °C TJmax accommodates enclosure temperatures up to 85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A (Bourns) | Same VWM (55.1 V), slightly higher VC (103 V at 3.9 A), SMB package (larger footprint) | Higher clamping voltage increases stress on protected ICs; requires larger PCB area | Select when higher surge current handling (3.9 A) is prioritized over board space and clamping tightness |
| 1.5SMC68A (ON Semiconductor) | Higher VWM (58.1 V), same VC (100 V at 4.2 A), SMC package (DO-214AB, 2.5 mm taller) | Reduced design margin between VWM and nominal rail voltage; less suitable for 48 V systems near upper limit | Prefer for cost-sensitive industrial designs where 1.5 kW peak power is unnecessary and taller profile is acceptable |
Compared with SMBJ64A and 1.5SMC68A, P4SMA62A-M3/61 offers tighter clamping (85.0 V), smaller SMA footprint, and lower VWM margin - making it optimal for space-constrained 48 V systems requiring minimal voltage overshoot during transients.

FAQ
What is the maximum clamping voltage of the P4SMA62A-M3/61 under standard test conditions?
The P4SMA62A-M3/61 has a maximum clamping voltage (VC) of 85.0 V when subjected to a 10/1000 µs waveform at 4.7 A peak pulse current. This value is measured per industry-standard surge testing methodology and reflects the highest voltage the protected circuit will experience during a transient event. The P4SMA62A-M3/61 maintains this clamping performance across its full operating temperature range and after repeated surge exposures, provided thermal limits are respected.
Is the P4SMA62A-M3/61 suitable for automotive applications?
Yes - the P4SMA62A-M3/61 uses halogen-free, RoHS-compliant materials and is part of the AEC-Q101-qualified P4SMA family (with HM3 suffix variants). While P4SMA62A-M3/61 itself carries the commercial-grade M3 suffix, its construction, thermal specs (TJmax = +150 °C), and electrical parameters align with automotive sensor interface and body electronics requirements. For formal automotive qualification, specify P4SMA62AHM3_A/H or equivalent AEC-Q101-coded variants.
What is the standoff voltage (VWM) of the P4SMA62A-M3/61, and how does it relate to system voltage selection?
The P4SMA62A-M3/61 has a standoff voltage (VWM) of 53.0 V, meaning it remains non-conductive up to this reverse voltage. This value provides a 10% margin below the nominal 48 V rail commonly used in industrial and telecom systems, ensuring no leakage or power loss during normal operation. Engineers select VWM ≥ 1.1× maximum steady-state voltage to avoid false triggering while preserving sufficient headroom for clamping action during transients.
Does the P4SMA62A-M3/61 require special PCB layout considerations for thermal performance?
Yes - the P4SMA62A-M3/61 achieves its rated 400 W peak pulse power only when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads increase thermal resistance and reduce surge capability. Use internal copper planes and thermal vias beneath pads where possible, especially in high-reliability applications. The device's RθJA = 120 °C/W assumes this minimum pad layout; deviations require derating per Figure 2 in document 88367.
How does the P4SMA62A-M3/61 compare to bidirectional TVS diodes like P4SMA62CA?
The P4SMA62A-M3/61 is unidirectional and intended for DC circuits with defined polarity, offering lower leakage and tighter VBR tolerance than its bidirectional counterpart P4SMA62CA. The latter supports AC or floating-line applications but exhibits higher reverse leakage and wider VBR spread. For 48 V DC power rails or unidirectional signal lines, P4SMA62A-M3/61 delivers superior clamping precision and lower standby current - critical for battery-powered or low-power systems where leakage impacts efficiency.
