Product details
Overview
P6SMB36CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 36 V standoff voltage (VWM), 49.9 V maximum clamping voltage at 12 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform.
For engineers reviewing the P6SMB36CA-M3/52 datasheet, P6SMB36CA-M3/52 pinout, P6SMB36CA-M3/52 application, or P6SMB36CA-M3/52 equivalent, key selection considerations include bidirectional transient suppression capability, low clamping ratio (VC/VWM ≈ 1.39), halogen-free RoHS compliance (M3 suffix), and suitability for automotive-grade designs when specified with HM3 suffix.
Technical Context
This device operates as a voltage-clamping protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The P6SMB36CA-M3/52 delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It supports continuous power dissipation up to 5.0 W at 50 °C ambient and operates across -65 °C to +150 °C junction temperature range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA-T | Same VWM (30.8 V), VC (49.9 V), and PPPM (600 W); identical SMB package but different manufacturer (Bourns) | Identical functional role; validated in same PCB footprints and test standards (IEC 61000-4-5) | Select when dual-sourcing or qualifying alternate supply chains without layout change |
| 1.5SMC36CA | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W); same electrical specs but larger SMC (DO-214AB) footprint | Requires PCB pad revision; suited for higher sustained power dissipation needs where SMB thermal limits are marginal | Choose only if system-level thermal modeling shows SMB thermal margin insufficient at full 5 W duty cycle |
Compared with SMBJ36CA-T and 1.5SMC36CA, the P6SMB36CA-M3/52 offers optimized thermal performance in the compact SMB outline and halogen-free compliance out-of-box, making it preferred for space-constrained, environmentally regulated, and high-volume commercial designs.

FAQ
What is the standoff voltage (VWM) of the P6SMB36CA-M3/52?
The P6SMB36CA-M3/52 has a standoff voltage (VWM) of 30.8 V, meaning it remains non-conductive up to this reverse voltage level with leakage current limited to 1.0 μA. This value ensures safe operation below the clamping threshold while allowing sufficient margin for normal signal or supply rail fluctuations in circuits where P6SMB36CA-M3/52 is deployed.
Is the P6SMB36CA-M3/52 suitable for automotive applications?
The P6SMB36CA-M3/52 itself is commercial-grade (M3 suffix), but Vishay offers the AEC-Q101 qualified variant as P6SMB36CAHM3_B/H or P6SMB36CAHM3_B/I. For automotive use, specify the HM3 suffix with appropriate revision code; the base P6SMB36CA-M3/52 is not AEC-Q101 certified and should be used only in non-automotive contexts unless explicitly validated.
What does the "CA" suffix indicate in P6SMB36CA-M3/52?
The "CA" suffix in P6SMB36CA-M3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB36A), the CA version has no cathode band marking and functions identically regardless of voltage polarity-critical for protecting AC signals or floating buses where direction is undefined.
How does the clamping voltage (VC) of P6SMB36CA-M3/52 compare to its breakdown voltage (VBR)?
The P6SMB36CA-M3/52 has a minimum breakdown voltage (VBR) of 34.2 V at 1 mA and a maximum clamping voltage (VC) of 49.9 V at 12 A IPPM. This yields a clamping ratio (VC/VBR) of approximately 1.46, confirming strong voltage-limiting performance. The relatively low ratio means P6SMB36CA-M3/52 effectively constrains overvoltages without excessive overshoot during high-current transients.
What is the maximum peak pulse current (IPPM) rating for P6SMB36CA-M3/52?
The P6SMB36CA-M3/52 is rated for a maximum peak pulse current (IPPM) of 12.0 A under the standard 10/1000 μs waveform condition. This value is derived directly from its 600 W peak pulse power rating and 49.9 V clamping voltage (IPPM = PPPM / VC). It reflects the highest transient current the device can safely divert without degradation when mounted per recommended pad layout.
