Product details
Overview
P6SMB62A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping transient overvoltages on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR at 1 mA), 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62A-M3/5B datasheet, P6SMB62A-M3/5B pinout, P6SMB62A-M3/5B application, or P6SMB62A-M3/5B equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant halogen-free construction, and AEC-Q101 qualification status for automotive-grade deployment.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable reverse-biased transient suppression. Its low incremental surge resistance and fast response time (<1 ns) enable effective protection against ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 150 °C maximum junction temperature and exhibits a 0.104 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across operating range. Thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads, supporting reliable power dissipation up to 5.0 W continuous.

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-E3/5B | Same SMB package, 64 V VWM, 71.1 V VBR, 103 V VC at 5.8 A; 400 W PPPM rating | Lower peak power handling limits suitability to less severe surge environments (e.g., consumer USB ports vs. industrial 48 V rails) | Select when system-level surge testing requires only IEC 61000-4-5 Level 2 compliance and board space constraints prioritize identical footprint |
| 1.5SMC62A | Same VWM/VBR specs but SMC (DO-214AB) package; 1.5 kW PPPM, higher thermal mass, larger footprint (7.11 mm × 6.22 mm) | Better thermal performance for high-duty-cycle surge events; not suitable for ultra-compact layouts requiring SMB size | Choose when long-term reliability under frequent surge exposure outweighs PCB area savings, and layout allows larger SMC outline |
Compared with SMAJ64A-E3/5B, P6SMB62A-M3/5B delivers 50% higher peak pulse power (600 W vs. 400 W) for demanding industrial transients, while versus 1.5SMC62A it trades thermal headroom for compactness - making it optimal for space-constrained 24–48 V systems needing AEC-Q101 readiness and halogen-free compliance.

FAQ
What is the maximum clamping voltage of P6SMB62A-M3/5B under a 10/1000 µs surge?
The maximum clamping voltage (VC) of P6SMB62A-M3/5B is 85.0 V at 7.1 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions defined in the Vishay datasheet (Document Number: 88370), and represents the highest voltage the protected circuit will experience during a 600 W transient event. Engineers must ensure downstream components have sufficient voltage margin above this clamping level.
Is P6SMB62A-M3/5B AEC-Q101 qualified?
P6SMB62A-M3/5B is manufactured using the same die and process as AEC-Q101 qualified variants; however, qualification requires the "_B" revision suffix (e.g., P6SMB62A-M3/5B_B). The base P6SMB62A-M3/5B part is commercial-grade and halogen-free (M3), but full AEC-Q101 certification applies only when explicitly ordered with the _B suffix. Always verify ordering code and certificate documentation for automotive applications.
What is the standoff voltage (VWM) of P6SMB62A-M3/5B, and how does it relate to system operating voltage?
The standoff voltage (VWM) of P6SMB62A-M3/5B is 53.0 V - the maximum DC or continuous AC voltage the device can withstand without entering breakdown. For reliable operation, system nominal voltage (e.g., 48 V DC) must remain below VWM with margin for ripple, tolerance, and temperature drift. This ensures the P6SMB62A-M3/5B remains non-conductive during normal operation while responding instantly to overvoltage events exceeding 58.9 V.
Can P6SMB62A-M3/5B be used in bidirectional configurations?
No - P6SMB62A-M3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., P6SMB62CA). Using P6SMB62A-M3/5B in reverse-biased AC or floating-signal applications risks permanent failure due to forward conduction during negative half-cycles. Always match device polarity to circuit topology.
What is the thermal resistance and power derating behavior of P6SMB62A-M3/5B?
P6SMB62A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per JEDEC standards. Its 5.0 W steady-state power dissipation derates linearly above 25 °C ambient, reaching zero at 150 °C junction temperature. Derating curves in Figure 2 of the Vishay datasheet (88370) confirm 3.5 W capability at 75 °C ambient - critical for enclosed industrial enclosures.
