Product details
Overview
P6SMB16A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping transient overvoltages 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-M3/5B datasheet, P6SMB16A-M3/5B pinout, P6SMB16A-M3/5B application, or P6SMB16A-M3/5B equivalent, this device delivers verified clamping performance, halogen-free RoHS compliance (M3 suffix), MSL Level 1 moisture sensitivity, and AEC-Q101 qualification readiness - critical for automotive-grade ESD/surge protection design-in and BOM continuity planning.
Technical Context
The P6SMB16A-M3/5B operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range (15.2–16.8 V). Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at VWM), while fast response time (<1.0 ns) enables suppression of ESD and lightning-induced transients before downstream components are damaged.
Thermal design relies on its RθJA of 100 °C/W and RθJL of 20 °C/W, with derating applied above TA = 25 °C per Figure 2. The cathode band identifies polarity, and mounting on 5.0 mm × 5.0 mm copper pads per JEDEC standard ensures rated 600 W pulse handling under repetitive 0.01% duty cycle conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below breakdown. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche conduction threshold; defines minimum clamping onset point. |
| VC (Clamping) | 22.5 V at 26.7 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines safe IC voltage margin. |
| PPPM | 600 W - Sustained transient energy absorption capacity; validates protection against IEC 61000-4-5 Level 4 surges. |
| IPPM | 26.7 A - Peak surge current handled at rated clamping voltage; correlates directly with line impedance and source energy. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood or enclosed industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount footprint with 5.59 mm × 4.06 mm body; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated terminals, MSL Level 1 (260 °C reflow peak), halogen-free and RoHS-compliant (M3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / low-side reference | Connected to ground or lower-potential rail in unidirectional TVS configuration; establishes reference for clamping. |
| Cathode | Reverse-biased input / protected line connection | Connected to the line being protected (e.g., 12 V rail, sensor output); conducts avalanche current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates robustness against high-energy transients like ISO 7637-2 Pulse 5a/b or IEC 61000-4-5 Combination Wave. |
| 22.5 V clamping voltage at 26.7 A | Ensures protected 3.3 V/5 V/12 V logic or analog circuits remain within absolute maximum ratings during surge events. |
| Glass-passivated junction | Delivers stable VBR tolerance (±5%), low leakage (<1 µA), and long-term reliability under thermal cycling. |
| Halogen-free, RoHS-compliant (M3) | Meets environmental compliance requirements for automotive and industrial end equipment without compromising performance. |
| AEC-Q101 qualification option (_B suffix) | Enables drop-in qualification path for automotive applications; P6SMB16A-M3/5B shares identical electrical specs with qualified variants. |
Applications

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-E3/5B | Same VWM (13.6 V), VBR (15.2–16.8 V), and VC (22.5 V), but in smaller SMA (DO-214AC) package with lower thermal mass (RθJA = 140 °C/W). | Limited to lower-duty-cycle or lower-average-power surge environments due to reduced heat dissipation. | Select when board space is constrained and peak surge energy remains within 400 W limits. |
| 1.5SMC16A | Same electrical specs but in larger SMC (DO-214AB) package; higher thermal mass (RθJA ≈ 70 °C/W) and 1500 W peak power rating. | Over-specified for 600 W use cases; adds cost and footprint without functional benefit for P6SMB16A-M3/5B's target applications. | Choose only if future-proofing for higher-energy threats or extended surge repetition is required. |
Compared with SMAJ16A-E3/5B, P6SMB16A-M3/5B offers superior thermal management in SMB package for sustained surge duty; versus 1.5SMC16A, it provides optimal size-performance balance for commercial/industrial 600 W protection without over-engineering.

FAQ
What is the maximum clamping voltage of the P6SMB16A-M3/5B under standard test conditions?
The P6SMB16A-M3/5B has a maximum clamping voltage (VC) of 22.5 V when subjected to a 10/1000 µs waveform at 26.7 A peak pulse current. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during a defined surge event. The P6SMB16A-M3/5B maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C), ensuring consistent protection in demanding environments.
Is the P6SMB16A-M3/5B suitable for automotive applications?
The P6SMB16A-M3/5B itself is halogen-free and RoHS-compliant (M3 suffix), and shares identical electrical specifications with AEC-Q101-qualified variants such as P6SMB16AHE3_B. While P6SMB16A-M3/5B is not individually certified, its design basis, process flow, and qualification-ready construction enable direct qualification path for automotive use. Engineers selecting P6SMB16A-M3/5B should verify final application compliance through system-level testing per ISO 16750-2.
What does the "/5B" suffix indicate in P6SMB16A-M3/5B?
The "/5B" suffix in P6SMB16A-M3/5B specifies packaging: 13-inch diameter plastic tape and reel containing 3200 units. This format supports high-volume SMT assembly with industry-standard feeder compatibility. The "M3" prefix denotes halogen-free, RoHS-compliant construction, while "A" indicates unidirectional polarity. No functional or electrical differences exist between /5B and other reel variants like /52 - only packaging quantity and reel size differ.
How does the P6SMB16A-M3/5B compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16A-M3/5B is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply rails), offering lower leakage (<1.0 µA at VWM) and tighter VBR tolerance. In contrast, P6SMB16CA is bidirectional, suited for AC or floating signal lines (e.g., RS-485), but exhibits higher leakage and slightly different VBR symmetry. The P6SMB16A-M3/5B cannot replace P6SMB16CA in AC-coupled applications without circuit redesign.
What is the thermal resistance specification for the P6SMB16A-M3/5B?
The P6SMB16A-M3/5B 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 JEDEC standard. Its junction-to-lead resistance (RθJL) is 20 °C/W. These values define safe power derating above 25 °C ambient and confirm suitability for PCB layouts with moderate copper area - critical for sustaining repetitive 600 W pulses at 0.01% duty cycle without thermal runaway. The P6SMB16A-M3/5B must be soldered per J-STD-020 MSL Level 1 profile.
