Product details
Overview
P6SMB62A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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 a 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62A-E3/52 datasheet, P6SMB62A-E3/52 pinout, P6SMB62A-E3/52 application, or P6SMB62A-E3/52 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101 qualification status for automotive-grade variants - all critical for ESD and lightning transient protection design validation.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging glass-passivated junction technology for stable reverse breakdown and low incremental surge resistance. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) define thermal limits under repetitive surge duty cycles.
The device responds within picoseconds to transients, with clamping action triggered when reverse voltage exceeds VWM = 53.0 V and fully engaged at VBR ≥ 58.9 V. It meets MSL Level 1 per J-STD-020 and supports automated SMT placement due to its low-profile SMB package and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
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 |
|---|---|---|---|
| SMAJ64A (Microchip) | Same SMB package; VWM = 55.1 V, VC = 103 V at 5.8 A - higher clamping voltage and lower IPPM. | Less effective clamping margin for 48 V systems where 85.0 V ceiling is critical; suitable only if downstream components tolerate >100 V surge. | Select P6SMB62A-E3/52 when tighter clamping (85.0 V vs. 103 V) and higher IPPM (7.1 A vs. 5.8 A) are required for robust 48 V rail protection. |
| 1.5SMC62A (ON Semiconductor) | Same VWM/VBR specs and SMB package; VC = 85.0 V at 7.1 A - identical clamping, but RθJA = 110 °C/W (vs. 100 °C/W). | Higher thermal resistance reduces safe operating area under repetitive surge conditions; requires larger copper pads for equivalent thermal performance. | Choose P6SMB62A-E3/52 for better thermal management in space-constrained layouts or high-duty-cycle environments. |
Compared with SMAJ64A and 1.5SMC62A, P6SMB62A-E3/52 delivers superior clamping precision (85.0 V), higher surge current handling (7.1 A), and lower thermal resistance (100 °C/W), making it optimal for compact, thermally demanding 48 V industrial and automotive protection designs.

FAQ
What is the maximum clamping voltage of P6SMB62A-E3/52 under a 10/1000 µs surge?
The P6SMB62A-E3/52 has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 7.1 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB62A-E3/52 RoHS-compliant and halogen-free?
Yes, P6SMB62A-E3/52 carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P6SMB62A-M3/52) must be selected. Both E3 and M3 versions meet JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.
Does P6SMB62A-E3/52 have AEC-Q101 qualification?
No, P6SMB62A-E3/52 itself is not AEC-Q101 qualified. However, Vishay offers automotive-grade variants under the HE3 and HM3 suffixes (e.g., P6SMB62AHE3_B), which include full AEC-Q101 stress testing and are marked with revision codes like "_B". The E3/52 version is intended for commercial and industrial applications where automotive qualification is not required.
What is the thermal resistance of P6SMB62A-E3/52, and how does it affect layout?
P6SMB62A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal PCB copper; increasing pad area or adding thermal vias reduces RθJA, directly improving surge repetition capability and long-term reliability under frequent transient exposure.
How does the glass passivation in P6SMB62A-E3/52 improve long-term reliability?
The glass passivated chip junction in P6SMB62A-E3/52 prevents moisture ingress and metallization migration at elevated temperatures and humidity, significantly reducing parametric drift in VBR and leakage current over time. This construction is validated per JESD22-A101 and JESD22-A110, making P6SMB62A-E3/52 suitable for outdoor, industrial, and automotive under-hood applications where environmental stress is severe.
