Product details
Overview
P6SMB16A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB16A-M3/52 datasheet, P6SMB16A-M3/52 pinout, P6SMB16A-M3/52 application, or P6SMB16A-M3/52 equivalent, this part delivers verified transient suppression for 12–15 V rail protection, meets J-STD-020 MSL Level 1, and supports automated SMT placement with halogen-free, RoHS-compliant construction.
Technical Context
The P6SMB16A-M3/52 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (15.2–16.8 V), then clamping to ≤22.5 V under 26.7 A transient current. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), critical for protecting sensitive CMOS inputs and low-voltage logic.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to +150 °C junction temperature. The SMB package's 0.205" × 0.220" footprint and matte tin-plated leads comply with J-STD-002 solderability standards and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for normal operating rail (e.g., 12 V systems). |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above nominal supply while avoiding false trips. |
| VC (Clamping) | 22.5 V at 26.7 A - Maximum voltage seen by protected circuit during 10/1000 µs surge; defines safe margin for 15 V-rated components. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges. |
| IPPM | 26.7 A - Peak pulse current corresponding to VC; determines minimum trace width and PCB copper area needed for thermal dissipation. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without active cooling. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 0.205" × 0.220" footprint; compatible with high-volume pick-and-place equipment. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity marked with cathode band. Dimensions: 3.94 mm × 2.20 mm × 1.52 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side (e.g., GND or return path); defines directionality of clamping action. |
| Cathode | Avalanche conduction terminal | Marked with band; connected to protected line (e.g., 12 V rail); conducts during overvoltage to shunt energy to ground. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 surges without derating in standard PCB layouts. |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving margin for 15 V logic and analog front-ends. |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress. |
| MSL Level 1 (260 °C peak) | Allows single-reflow assembly without moisture sensitivity concerns or baking requirements. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets environmental compliance for automotive and industrial end-equipment without compromising surge performance. |
Applications
| Industrial Power Supply Protection | Automotive Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/52 | Same VWM (13.6 V), identical SMB package, but lower PPPM (400 W) and higher VC (26.5 V at 15.1 A). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); insufficient for IEC 61000-4-5 Level 3. | Select when cost sensitivity outweighs surge margin and system-level testing confirms 400 W adequacy. |
| 1.5SMC16A | Same electrical specs (VWM, VBR, VC), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) and higher thermal mass. | Better thermal performance (RθJA ≈ 60 °C/W), but incompatible with dense layouts requiring SMB footprint. | Choose when board space allows and enhanced thermal endurance is required for high-duty-cycle surge environments. |
Compared with SMAJ16A-E3/52, P6SMB16A-M3/52 delivers 50% higher surge power headroom and tighter clamping; versus 1.5SMC16A, it offers identical protection in a 40% smaller footprint - critical for space-constrained industrial modules.

FAQ
What is the maximum clamping voltage of P6SMB16A-M3/52 under rated surge conditions?
The P6SMB16A-M3/52 has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated 26.7 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB16A-M3/52 maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P6SMB16A-M3/52 suitable for automotive applications?
Yes - the P6SMB16A-M3/52 is halogen-free and RoHS-compliant (M3 suffix), and an AEC-Q101 qualified version (P6SMB16AHM3_B/H) is available. While the base P6SMB16A-M3/52 itself is commercial-grade, its construction - including glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max - aligns with automotive subsystem requirements such as body control modules and sensor interfaces. For certified deployment, specify the HM3_B variant.
How does the M3 suffix affect P6SMB16A-M3/52 compared to E3 versions?
The M3 suffix on P6SMB16A-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance - identical electrically to E3 versions but optimized for stricter environmental compliance. Both share identical VWM, VBR, VC, and thermal specs; the M3 variant replaces brominated flame retardants in the molding compound while maintaining UL 94 V-0 flammability rating.
What is the reverse leakage current of P6SMB16A-M3/52 at its stand-off voltage?
At its 13.6 V stand-off voltage (VWM) and TA = 25 °C, the P6SMB16A-M3/52 exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss and no interference with bias networks in precision analog or low-power sensor circuits. Leakage remains below 5 µA up to 80% of VWM, supporting stable operation in battery-powered designs.
Can P6SMB16A-M3/52 be used in bidirectional configurations?
No - P6SMB16A-M3/52 is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., P6SMB16CA). Using P6SMB16A-M3/52 in reverse-biased configurations risks forward conduction and failure; for AC line or differential signal protection, select the explicitly bidirectional P6SMB16CA-M3/52 variant instead.
