Product details
Overview
P6SMB10A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 10 V standoff voltage (VWM), 14.5 V clamping voltage at 41.4 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform - deployed for overvoltage protection of 5 V–12 V logic lines and I/O interfaces in industrial sensor modules.
For engineers reviewing the P6SMB10A-M3/52 datasheet, P6SMB10A-M3/52 pinout, P6SMB10A-M3/52 application, or P6SMB10A-M3/52 equivalent, key selection criteria include unidirectional polarity, 8.55 V maximum reverse standoff, 10.5 V minimum breakdown voltage at 1 mA, and halogen-free RoHS-compliant construction under M3 suffix.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when transient voltage exceeds its breakdown threshold (9.50–10.5 V at 1 mA), limiting downstream voltage to ≤14.5 V at 41.4 A. Its glass-passivated junction ensures stable leakage (<10 μA at 8.55 V) and fast response time (<1 ns).
Designed for automated SMT assembly on standard PCB pads (0.2" × 0.2"), it delivers 600 W surge handling with 0.01% duty cycle, thermal resistance of 100 °C/W (junction-to-ambient), and operates across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - Maximum continuous reverse voltage before significant leakage; compatible with 5 V–9 V supply rails. |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - Avalanche onset range defining reliable clamping initiation point. |
| VC (Clamping) | 14.5 V at IPPM = 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge. |
| PPPM | 600 W - Surge energy absorption capacity under standardized 10/1000 μs waveform. |
| ID (Leakage) | ≤10 μA at VWM - Ensures minimal loading on low-power signal or sensor lines. |
| Package | SMB (DO-214AA) - Surface-mount footprint with 5.59 mm × 4.06 mm body; supports JEDEC-compliant reflow. |
| Construction | Halogen-free, RoHS-compliant (M3 suffix); meets JESD201 Class 2 whisker resistance. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-indicated by band. Terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential; completes clamping path during positive transients. |
| Cathode | Protected line input | Banded end; connects to signal/power line requiring transient suppression (e.g., USB VBUS, RS-485 A/B). |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles high-energy ESD and lightning-induced surges without degradation under 10/1000 μs waveform. |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage performance across temperature and life cycles. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or special handling. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., IEC 61000-4-5 ring wave). |
| Halogen-free (M3 suffix) | Fulfills strict environmental compliance requirements for automotive and industrial end equipment. |
Applications
| Industrial Sensor Interface | USB Power Line Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to motor switching noise in factory automation cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor output and ADC input to limit fault voltage to safe levels. Use Value: Prevents latch-up or damage to 12-bit SAR ADCs operating at 3.3 V or 5 V while maintaining <10 μA leakage. |
Use Scenario: Safeguarding 5 V VBUS line in embedded USB host ports against hot-plug induced surges and ESD events. IC Role / Device Role / Timing Role: Standoff-rated TVS connected anode-to-ground, cathode-to-VBUS to clamp transients before reaching USB controller. Use Value: Maintains VBUS integrity below 14.5 V during 30 A IEC 61000-4-5 surge, preserving USB enumeration and power delivery. |
| RS-485 Transceiver Port | DC-DC Converter Input |
Use Scenario: Shielding half-duplex RS-485 bus nodes from ground bounce and cable discharge events in building control networks. IC Role / Device Role / Timing Role: Bidirectional protection not applicable here; P6SMB10A-M3/52 used in unidirectional configuration on receiver-side bias rail. Use Value: Clamps common-mode spikes to ≤14.5 V, preventing false triggering or damage to isolated RS-485 transceivers (e.g., ADM2483). |
Use Scenario: Suppressing switch-node ringing and load-dump transients on 12 V input of buck converters powering FPGA core supplies. IC Role / Device Role / Timing Role: Primary-line TVS placed upstream of input filter capacitor to absorb energy before LC stage. Use Value: Limits input voltage excursions to 14.5 V during 100 V/10 ms load dump, avoiding overvoltage shutdown of controller ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, identical VWM (8.55 V) and VC (14.5 V), but rated at 400 W PPPM (vs. 600 W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 level 3/4 testing. | Select SMAJ10A only when system-level surge requirements are ≤400 W and cost sensitivity outweighs margin. |
| 1.5SMC10A | Higher-power 1500 W rating in larger SMC (DO-214AB) package; VWM = 8.55 V, VC = 14.5 V, same breakdown range. | Requires larger PCB area and different pad layout; not drop-in compatible with SMB footprints. | Choose 1.5SMC10A when higher surge immunity is required and board space allows SMC package relocation. |
Compared with SMAJ10A and 1.5SMC10A, P6SMB10A-M3/52 uniquely balances 600 W surge capability, SMB footprint compatibility, and halogen-free compliance - making it optimal for space-constrained industrial and automotive-qualified designs where both performance and regulatory alignment matter.

FAQ
What is the maximum clamping voltage of the P6SMB10A-M3/52 under surge conditions?
The P6SMB10A-M3/52 has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A using the 10/1000 μs waveform. This value is measured at the instant of peak current and defines the upper voltage limit imposed on the protected circuit during transient events. The P6SMB10A-M3/52 maintains this clamping performance across its specified operating temperature range and after repeated surge exposures within datasheet limits.
Is the P6SMB10A-M3/52 suitable for bidirectional signal line protection?
No, the P6SMB10A-M3/52 is a unidirectional TVS diode, indicated by its "A" suffix and cathode band marking. It conducts only during positive transients relative to ground. For bidirectional protection (e.g., AC-coupled data lines), the P6SMB10CA-M3/52 variant must be used. Using P6SMB10A-M3/52 on bidirectional lines risks forward conduction during negative excursions and inadequate protection.
Does the P6SMB10A-M3/52 meet AEC-Q101 qualification?
No, the P6SMB10A-M3/52 is not AEC-Q101 qualified. Its M3 suffix denotes halogen-free, RoHS-compliant commercial-grade construction. For automotive applications requiring AEC-Q101, the correct part is P6SMB10AHM3_B/H or P6SMB10AHM3_B/I - which carry the HM3_B or HM3_I suffix and are explicitly tested to AEC-Q101 stress requirements.
What is the thermal resistance of the P6SMB10A-M3/52, and how does it affect PCB layout?
The P6SMB10A-M3/52 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. To maintain safe operation under sustained power dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks. Reducing pad size or omitting thermal vias increases RθJA and may cause premature thermal shutdown or parametric shift during repetitive surges.
How does the M3 suffix differ from the E3 suffix in P6SMB10A-M3/52 versus P6SMB10A-E3/52?
The M3 suffix in P6SMB10A-M3/52 indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, while the E3 suffix in P6SMB10A-E3/52 denotes standard RoHS compliance without halogen-free assurance. Both share identical electrical specs and SMB packaging, but P6SMB10A-M3/52 satisfies stricter environmental mandates (e.g., IEC 61249-2-21) required in automotive and green industrial programs.
