Product details
Overview
P6SMB62A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA test current, and clamps transients to ≤85.0 V at 7.1 A peak pulse current (IPPM) under 10/1000 μs waveform - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the P6SMB62A-M3/52 datasheet, P6SMB62A-M3/52 pinout, P6SMB62A-M3/52 application, or P6SMB62A-M3/52 equivalent, this page delivers verified electrical parameters, thermal derating behavior, SMB package mechanical data, and validated alternatives for ESD/surge protection design-in and BOM rationalization.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche response. Its 600 W peak pulse power rating (10/1000 μs) and low incremental surge resistance enable effective suppression of inductive switching spikes and lightning-induced surges without latch-up or degradation.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, typical) and RθJL = 20 °C/W (junction-to-lead), supporting reliable operation up to TJ = +150 °C. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/52 (Vishay) | Same SMB package; VWM = 55.1 V, VC = 103 V at 5.8 A - higher clamping voltage, lower IPPM | Less effective clamping headroom for 48 V systems requiring sub-90 V protection | Select when higher VWM margin is needed and clamping voltage >85 V is acceptable |
| 1.5SMC62A (ON Semiconductor) | SAME VWM/VBR/VC specs; identical SMB footprint; 600 W rating; RoHS-compliant but not halogen-free | No AEC-Q101 qualified variant; M3 suffix unavailable | Choose for cost-sensitive commercial designs where halogen-free compliance is not mandated |
Compared with SMAJ64A-E3/52 and 1.5SMC62A, P6SMB62A-M3/52 delivers tighter clamping (85.0 V vs. 103 V), halogen-free construction, and direct AEC-Q101 qualification path - making it optimal for space-constrained, high-reliability 48 V industrial and automotive protection.

FAQ
What is the maximum clamping voltage of P6SMB62A-M3/52 under a 10/1000 μs surge?
The P6SMB62A-M3/52 clamps to a maximum of 85.0 V when subjected to its rated peak pulse current of 7.1 A under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and confirmed in the Vishay datasheet revision 09-Jan-2024, ensuring predictable protection for downstream components operating near 48 V or 60 V rails. The P6SMB62A-M3/52 maintains this clamping performance across its full operating temperature range.
Does P6SMB62A-M3/52 meet automotive qualification standards?
The base P6SMB62A-M3/52 is commercial-grade and halogen-free/RoHS-compliant, but not AEC-Q101 qualified. However, Vishay offers the P6SMB62AHM3_B variant - identical electrical specs and SMB package - which is fully AEC-Q101 qualified for automotive applications. Engineers designing for automotive ECUs should specify the HM3_B suffix to ensure qualification compliance while retaining the same protection characteristics of the P6SMB62A-M3/52.
What is the thermal resistance of P6SMB62A-M3/52, and how does it affect PCB layout?
P6SMB62A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe junction temperatures under repetitive surges, the PCB must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal as specified in the datasheet. Reducing pad size increases RθJA, risking thermal overload - so layout adherence is critical for P6SMB62A-M3/52 reliability in high-duty-cycle applications.
How does the M3 suffix differ from E3 in P6SMB62A-M3/52?
The M3 suffix in P6SMB62A-M3/52 indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, whereas E3 denotes RoHS-compliant but standard brominated flame-retardant molding compound. Both share identical electrical specs and SMB packaging, but P6SMB62A-M3/52 meets stricter environmental mandates (e.g., EU ELV, China RoHS II) and is preferred for green-design programs. The "/52" denotes 7" tape-and-reel packaging with 750 units per reel.
Can P6SMB62A-M3/52 be used in bidirectional protection circuits?
No - P6SMB62A-M3/52 is strictly unidirectional, as indicated by the "A" suffix and cathode-band marking. For bidirectional protection, Vishay specifies the CA-suffixed variant (e.g., P6SMB62CA-M3/52), which provides symmetrical clamping in both polarities. Using P6SMB62A-M3/52 in a bidirectional configuration would result in forward conduction and failure during negative transients. Always match suffix ("A" = unidirectional, "CA" = bidirectional) to circuit polarity requirements.
