Product details
Overview
P6SMB62A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients 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 capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62A-E3/5B datasheet, P6SMB62A-E3/5B pinout, P6SMB62A-E3/5B application, or P6SMB62A-E3/5B equivalent, this part delivers verified transient suppression performance in automotive-qualified (AEC-Q101 option available), RoHS-compliant, commercial-grade packaging with MSL Level 1 moisture sensitivity and matte tin-plated leads solderable per J-STD-002.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp overvoltage events before they damage downstream components. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while low incremental surge resistance (rd) maintains tight clamping under high-current transients.
The device is rated for continuous power dissipation of 5.0 W at 50 °C on infinite heatsink, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It supports operating junction temperatures from –65 °C to +150 °C and handles 100 A non-repetitive forward surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 (Microchip) | 64 V VWM, 71.1–78.6 V VBR, 103 V VC at 5.8 A; same SMB package but higher clamping voltage (+18 V) and lower IPPM. | Less effective clamping margin for 60 V-rated components; suitable only where protected ICs tolerate >100 V transient exposure. | Select SMAJ64A only if board layout restricts replacement to identical footprint and original design already accommodates higher VC. |
| 1.5SMC68A (ON Semiconductor) | 68 V VWM, 75.6–83.6 V VBR, 112 V VC at 5.3 A; larger SMC (DO-214AB) package (0.280" × 0.165"), incompatible with SMB land pattern. | Requires PCB redesign due to larger pad layout and 20 % higher clamping voltage; not drop-in. | Choose 1.5SMC68A only when higher power rating (1500 W) justifies mechanical redesign and thermal derating analysis confirms improved junction temperature margin. |
Compared with SMAJ64A and 1.5SMC68A, P6SMB62A-E3/5B provides the lowest clamping voltage (85.0 V) in SMB footprint, enabling tighter voltage margining for 60–80 V system rails without layout change or thermal compromise.

FAQ
What is the maximum clamping voltage of P6SMB62A-E3/5B under standard test conditions?
The maximum clamping voltage of P6SMB62A-E3/5B is 85.0 V, measured at a peak pulse current (IPPM) of 7.1 A using the industry-standard 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage the protected circuit will experience during a transient event. P6SMB62A-E3/5B achieves this with low incremental resistance, making it suitable for safeguarding 60 V-rated power MOSFETs and interface ICs.
Is P6SMB62A-E3/5B RoHS-compliant and halogen-free?
Yes, P6SMB62A-E3/5B carries the "E3" suffix, indicating it is RoHS-compliant and meets commercial-grade environmental requirements per JEDEC standards. It is not halogen-free - that designation applies to "M3" variants (e.g., P6SMB62A-M3/5B). The E3 version uses matte tin-plated leads and complies with JESD 201 Class 2 whisker resistance testing, making it suitable for lead-free reflow assembly without preconditioning.
Can P6SMB62A-E3/5B be used in automotive applications?
P6SMB62A-E3/5B itself is commercial-grade, but Vishay offers AEC-Q101-qualified versions in the same P6SMB family (e.g., P6SMB62AHE3_B). These variants undergo extended stress testing for temperature cycling, humidity, and mechanical shock, qualifying them for under-hood and body electronics. For automotive use, specify the HE3 or HM3 suffix and confirm qualification status via Vishay's official documentation - P6SMB62A-E3/5B alone does not carry AEC-Q101 certification.
What is the thermal resistance of P6SMB62A-E3/5B and how does it affect power handling?
P6SMB62A-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. At ambient temperatures above 25 °C, its 5.0 W steady-state power dissipation must be derated linearly - for example, to ~3.5 W at 75 °C ambient. Proper copper pad layout (0.2" × 0.2" per terminal) is essential to achieve these ratings; insufficient copper reduces effective heat transfer and risks thermal runaway during repetitive surges.
How does the VBR tolerance of P6SMB62A-E3/5B impact circuit protection design?
P6SMB62A-E3/5B has a specified VBR range of 58.9 V to 65.1 V at 1 mA test current, representing a ±5 % tolerance. This means the actual breakdown may occur as low as 58.9 V - requiring designers to ensure all downstream components (e.g., MOSFETs, regulators) have sufficient margin above this minimum. For instance, pairing P6SMB62A-E3/5B with a 60 V-rated device risks premature conduction; a 65 V or higher rating is recommended. The tight tolerance ensures consistent clamping behavior across production lots.
