Product details
Overview
P6SMB510A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 510 V standoff voltage (VWM), 698 V clamping voltage (VC) at 0.86 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial power supplies and telecom interfaces.
For engineers reviewing the P6SMB510A-E3/5B datasheet, P6SMB510A-E3/5B pinout, P6SMB510A-E3/5B application, or P6SMB510A-E3/5B equivalent, key selection criteria include unidirectional polarity, 510 V stand-off rating, 698 V clamping performance under 0.86 A surge, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 510 V (VWM), it avalanches at 485–535 V (VBR, min/max @ 1 mA), limiting transient energy by diverting surge current to ground. Its low incremental surge resistance ensures stable clamping during repetitive 10/1000 μs pulses at 0.01% duty cycle.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, enabling operation up to TJ = 150 °C. The glass-passivated junction and MSL Level 1 moisture sensitivity rating support lead-free reflow up to 260 °C peak, meeting J-STD-020 requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ510A | Same VWM (510 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for 600 W surge requirements per IEC 61000-4-5 | Select P6SMB510A-E3/5B when 600 W clamping and SMB mechanical robustness are required. |
| 1.5SMC510A | Same VWM (510 V), same PPPM (600 W), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Requires more PCB area; better thermal dissipation (RθJA ≈ 60 °C/W) for high-duty-cycle use | Choose P6SMB510A-E3/5B for space-constrained designs where SMB footprint and 5.59 mm × 4.06 mm size are critical. |
Compared with SMAJ510A and 1.5SMC510A, P6SMB510A-E3/5B delivers identical 510 V standoff and 600 W surge rating in the smallest standardized 600 W TVS package, balancing board space, thermal performance, and surge margin for industrial and telecom deployments.

FAQ
What is the clamping voltage of P6SMB510A-E3/5B and how is it measured?
The clamping voltage (VC) of P6SMB510A-E3/5B is 698 V, measured at a peak pulse current (IPPM) of 0.86 A using a 10/1000 μs double-exponential waveform. This value represents the maximum voltage that appears across the device during a standardized surge event, ensuring downstream components see no more than 698 V. The test condition is defined in the Vishay datasheet document 88370 and applies under TA = 25 °C with specified PCB pad layout.
Is P6SMB510A-E3/5B RoHS-compliant and what does the "E3" suffix indicate?
Yes, P6SMB510A-E3/5B is RoHS-compliant. The "E3" suffix denotes Vishay's commercial-grade, lead-free, RoHS-compliant construction with matte tin-plated terminals meeting J-STD-002 and JESD 22-B102 solderability standards. It also satisfies JESD 201 Class 2 whisker resistance testing, confirming long-term interconnect reliability in automated assembly processes.
Can P6SMB510A-E3/5B be used in bidirectional configurations?
No, P6SMB510A-E3/5B is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB510CA). Using P6SMB510A-E3/5B in bidirectional signal paths would result in forward conduction during negative transients, causing failure. For AC or differential line protection, select the CA version instead.
What is the thermal resistance and maximum operating temperature of P6SMB510A-E3/5B?
P6SMB510A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 5.0 mm × 5.0 mm copper pads. Its maximum operating junction temperature is +150 °C, allowing reliable operation in industrial enclosures with ambient temperatures up to +85 °C when properly heatsinked via PCB copper.
How does the "5B" in P6SMB510A-E3/5B affect packaging and ordering?
The "5B" denotes the tape-and-reel packaging variant: 13-inch diameter reel containing 3200 units, optimized for high-volume SMT placement. It differs from "52" (7-inch reel, 750 units) and does not affect electrical or thermal specifications. The "5B" format ensures consistent feeder compatibility and minimizes changeover downtime in automated production lines handling P6SMB510A-E3/5B.
