For engineers reviewing the P6SMB82CA-M3/52 datasheet, P6SMB82CA-M3/52 pinout, P6SMB82CA-M3/52 application, or P6SMB82CA-M3/52 equivalent, this device delivers verified bidirectional clamping performance, halogen-free RoHS compliance (M3 suffix), and J-STD-020 MSL Level 1 moisture sensitivity - critical for high-reliability automated SMT assembly and automotive-grade derivative qualification paths.
Technical Context
The P6SMB82CA-M3/52 operates as a silicon avalanche diode with symmetrical bidirectional breakdown behavior, enabling identical clamping in both polarities without polarity marking. Its glass-passivated junction ensures stable leakage and low incremental surge resistance under repetitive transient stress.
Designed for transient suppression per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it exhibits 100 °C/W junction-to-ambient thermal resistance and supports operation from −65 °C to +150 °C, with derating above 25 °C per Figure 2 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA-T3 | Same SMB package, 600 W PPPM, but VWM = 70.1 V, VC = 113 V - identical electrical specs; differs only in packaging (tape-and-reel vs. bulk) and manufacturer (Bourns vs. Vishay) | Identical use cases; validated in same reference designs for industrial I/O modules | Select when dual-sourcing is required or Bourns supply chain preference applies |
| 1.5SMC82CA | Higher-power 1500 W variant in larger SMC (DO-214AB) package; VWM = 70.1 V, VC = 113 V - same clamping but 2.5× footprint and thermal mass | Preferred for higher-energy environments (e.g., railway signaling) where PCB space allows larger package | Choose only if system-level surge testing exceeds 600 W capability or thermal cycling demands lower junction temperature rise |
Compared with SMBJ82CA-T3, P6SMB82CA-M3/52 offers identical clamping performance and halogen-free compliance but with Vishay's AEC-Q101 qualification pathway; versus 1.5SMC82CA, it trades power headroom for 40% smaller PCB area and faster reflow compatibility.

FAQ
What is the maximum clamping voltage of the P6SMB82CA-M3/52 under a 10/1000 μs transient?
The P6SMB82CA-M3/52 has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB82CA-M3/52 maintains this clamping performance bidirectionally due to its symmetrical avalanche structure.
Is the P6SMB82CA-M3/52 suitable for automotive applications?
The P6SMB82CA-M3/52 itself is commercial-grade, but Vishay offers the automotive-qualified variant P6SMB82CA-HM3_B (with AEC-Q101 qualification) using the same die and SMB package. The P6SMB82CA-M3/52 shares identical electrical characteristics and thermal behavior, making it suitable for pre-qualification prototyping or non-safety-critical automotive subsystems where full AEC-Q101 documentation is not mandated. For production automotive use, specify the HM3_B suffix version.
Does the P6SMB82CA-M3/52 have polarity markings on the package?
No, the P6SMB82CA-M3/52 does not feature polarity markings because it is a bidirectional TVS diode. Its symmetrical construction means either terminal functions as anode or cathode depending on the instantaneous polarity of the transient voltage - eliminating orientation concerns during placement. This contrasts with unidirectional variants (e.g., P6SMB82A) that include a cathode band marking.
What is the junction-to-ambient thermal resistance (RθJA) of the P6SMB82CA-M3/52?
The typical junction-to-ambient thermal resistance (RθJA) of the P6SMB82CA-M3/52 is 100 °C/W when mounted on the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value assumes still air conditions and is used to calculate junction temperature rise under steady-state power dissipation. For the P6SMB82CA-M3/52, this thermal characteristic supports reliable operation up to +150 °C junction temperature when derated per Figure 2 of the Vishay datasheet.
How does the M3 suffix affect the P6SMB82CA-M3/52 compared to the E3 version?
Both P6SMB82CA-M3/52 and P6SMB82CA-E3/52 are RoHS-compliant, but the M3 suffix indicates halogen-free molding compound and plating, whereas E3 uses standard RoHS-compliant materials that may contain halogens. The P6SMB82CA-M3/52 meets additional environmental standards including JEDEC J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance. Functionally, the P6SMB82CA-M3/52 performs identically to the E3 variant in all electrical and thermal parameters.
