Product details
Overview
P6SMB75CA-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 or power lines. It features a 75 V standoff voltage (VWM), 82.9 V minimum breakdown voltage (VBR), 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB75CA-M3/52 datasheet, P6SMB75CA-M3/52 pinout, P6SMB75CA-M3/52 application, or P6SMB75CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.24), halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard PCB pads. Its M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 75 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown) | 82.9 V min - Avalanche conduction initiates reliably above this voltage; ensures consistent turn-on under transient stress |
| VC (Clamping) | 103 V max at IPPM = 5.8 A - Limits voltage seen by protected circuit during 600 W surge; clamping ratio = 1.24 |
| PPPM | 600 W - Peak transient power it can absorb per 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 4 surges |
| ID (Leakage) | 1.0 μA max at VWM - Negligible standby current; avoids loading sensitive analog or low-power circuits |
| TJ max | 150 °C - Enables operation in high-temperature environments such as automotive engine bays or industrial enclosures |
| Package | SMB (DO-214AA) - Standardized 2-pin SMD outline with 5.59 mm × 4.06 mm footprint; compatible with JEDEC MS-012AC |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Either terminal serves as input/output for bidirectional clamping; no cathode band marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity concerns |
| 600 W peak pulse power | Supports robust immunity to IEC 61000-4-5 surge events up to 4 kV (open-circuit) in properly laid-out PCBs |
| Halogen-free & RoHS-compliant (M3) | Meets environmental compliance requirements for industrial and consumer electronics without compromising reliability |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak - eliminates baking requirements pre-assembly |
| Low clamping ratio (VC/VBR ≈ 1.24) | Minimizes overvoltage stress on downstream components compared to higher-ratio TVS devices |
Applications
| Industrial Power Supply Input Protection | Automotive Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V DC input rails in PLC modules against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed across input terminals upstream of DC-DC converter.

Use Scenario: Safeguarding LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control units. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on differential or single-ended sensor lines near connector interface. Use Value: Suppresses ESD (±15 kV contact) and coupled noise without distorting low-speed analog signals due to minimal leakage (1 μA). |

IC Role / Device Role / Timing Role: Localized TVS at motor driver IC inputs and feedback nodes exposed to commutation spikes. Use Value: Absorbs repetitive 600 W inductive kickback pulses without degradation, extending MCU lifetime in high-duty-cycle applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA-T | Same VWM (75 V), VC = 121 V at 4.9 A; lower PPPM (600 W same), higher clamping ratio (1.61) | Less effective clamping headroom; requires higher layout margin to avoid overstress of protected ICs | Acceptable where tighter voltage margins are not critical and cost is prioritized over clamping performance |
| 1.5SMC75CA | Same VWM/VC specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs. 100 °C/W for SMB | Better thermal dissipation in high-repetition-rate surge environments; occupies ~2.5× PCB area | Preferred for high-duty-cycle industrial applications where board space permits and thermal management is essential |
Compared with P6SMB75CA-M3/52, SMBJ75CA-T offers identical voltage ratings but weaker clamping performance, while 1.5SMC75CA delivers superior thermal handling at the cost of footprint size - making P6SMB75CA-M3/52 optimal for space-constrained, high-volume SMT designs requiring balanced surge immunity and layout efficiency.

FAQ
What does the "CA" suffix indicate in P6SMB75CA-M3/52?
The "CA" suffix in P6SMB75CA-M3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB75A), it has no cathode marking and functions identically regardless of voltage polarity - ideal for AC lines, differential buses, or floating signal paths where directionality is undefined.
Is P6SMB75CA-M3/52 suitable for automotive applications?
P6SMB75CA-M3/52 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB75CAHM3_B/H variant with AEC-Q101 qualification. The P6SMB75CA-M3/52 remains appropriate for non-safety-critical automotive subsystems like infotainment or body electronics where full qualification is not mandated, provided system-level validation confirms robustness.
How does the clamping voltage of P6SMB75CA-M3/52 compare to its breakdown voltage?
The P6SMB75CA-M3/52 has a minimum breakdown voltage (VBR) of 82.9 V and a maximum clamping voltage (VC) of 103 V at 5.8 A IPPM, yielding a clamping ratio of approximately 1.24. This tight ratio ensures minimal overvoltage stress on protected components - significantly better than many competing TVS diodes with ratios >1.4 - and reflects optimized junction design and low dynamic impedance.
What is the significance of the "M3" suffix in P6SMB75CA-M3/52?
The "M3" suffix in P6SMB75CA-M3/52 indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and JEDEC MSL Level 1 reflow requirements (260 °C peak). It assures compatibility with lead-free assembly processes, eliminates brominated flame retardants, and supports environmental compliance mandates for industrial and consumer electronics without sacrificing electrical performance.
Can P6SMB75CA-M3/52 be used in place of a unidirectional TVS like P6SMB75A?
No - P6SMB75CA-M3/52 is bidirectional and lacks polarity marking, while P6SMB75A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: P6SMB75CA-M3/52 works only where symmetrical clamping is needed (e.g., AC lines), whereas P6SMB75A is mandatory for DC rail protection with defined polarity. Using P6SMB75CA-M3/52 in a unidirectional design may cause unintended conduction during normal operation.
