Product details
Overview
P6SMB13AHM3_B/I 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 11.1 V stand-off voltage (VWM), 12.4–13.7 V breakdown voltage (VBR) at 1 mA, 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB13AHM3_B/I datasheet, P6SMB13AHM3_B/I pinout, P6SMB13AHM3_B/I application, or P6SMB13AHM3_B/I equivalent, this device delivers AEC-Q101 qualified transient suppression with halogen-free RoHS compliance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial control modules requiring validated surge immunity.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient overvoltage exceeds VBR, then rapidly switches to low-impedance conduction to clamp voltage at ≤18.2 V. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed for PCB-level protection, P6SMB13AHM3_B/I uses SMB (DO-214AA) packaging with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. The "HM3" suffix confirms halogen-free, RoHS-compliant construction; "_B/I" denotes AEC-Q101 qualification and 13" tape-and-reel delivery (3200 pcs/reel).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 12.4–13.7 V at 1 mA - precise voltage threshold where avalanche conduction initiates; tight tolerance supports predictable protection timing. |
| VC (Clamping) | 18.2 V at 33.0 A (10/1000 µs) - maximum voltage seen by protected circuit during worst-case surge; enables robust 12 V rail protection. |
| PPPM | 600 W - peak pulse power handling capability; sustains 33 A surges without failure under standard test conditions. |
| IPPM | 33.0 A - peak pulse current supported at rated clamping voltage; validates protection against IEC 61000-4-5 Level 3 surges. |
| TJ max. | +150 °C - maximum junction temperature; allows operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | SMB (DO-214AA) - standardized 2-pin surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on body; polarity-critical for unidirectional operation.
| 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 | Reverse voltage input / Clamping output | Connected to protected line (e.g., 12 V supply or signal trace); conducts surge current to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for ECU, ADAS, and body electronics. |
| Halogen-free & RoHS-compliant (HM3) | Meets global environmental regulations and eliminates corrosive halogen emissions during reflow or end-of-life processing. |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity up to 1 kV open-circuit / 0.5 kV source impedance - sufficient for 12 V system bus protection. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on downstream components; enables tighter design margins versus higher-ratio suppressors. |
| MSL Level 1 (260 °C peak) | Allows single-reflow assembly without baking; reduces manufacturing complexity and cost in high-volume SMT lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5B | Same VWM (11.1 V), identical SMB package, but only commercial-grade (not AEC-Q101 qualified); 5.0 W steady-state power vs. same 600 W pulse rating. | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 is not mandated. | Select SMAJ13A-E3/5B when cost sensitivity outweighs automotive reliability requirements and full AEC-Q101 validation is unnecessary. |
| 1.5SMC13A | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W), same VBR range but SMC (DO-214AB) package - 2.5 mm wider, requiring PCB layout change. | Lower power density and larger footprint; less suitable for space-constrained automotive modules. | Choose 1.5SMC13A only if existing SMC footprint is fixed and AEC-Q101 is not required; otherwise, P6SMB13AHM3_B/I offers superior thermal performance and qualification. |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, P6SMB13AHM3_B/I uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized SMB thermal performance - making it the preferred choice for next-generation automotive and high-reliability industrial designs where regulatory compliance and long-term supply continuity are mandatory.

FAQ
What is the maximum clamping voltage of P6SMB13AHM3_B/I under a 10/1000 µs surge?
The maximum clamping voltage (VC) of P6SMB13AHM3_B/I is 18.2 V when subjected to a 33.0 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. P6SMB13AHM3_B/I maintains this clamping performance across its specified operating temperature range.
Is P6SMB13AHM3_B/I qualified for automotive applications?
Yes, P6SMB13AHM3_B/I is AEC-Q101 qualified, as confirmed by the "_B" suffix in its ordering code and Vishay's official documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance - validating its suitability for under-hood and chassis-mounted automotive electronics such as engine control modules and ADAS sensors. P6SMB13AHM3_B/I meets all requirements for automotive-grade TVS deployment.
What does the "HM3" suffix mean in P6SMB13AHM3_B/I?
The "HM3" suffix in P6SMB13AHM3_B/I indicates halogen-free, RoHS-compliant construction per Vishay's material categorization standards. It confirms the molding compound contains no brominated or chlorinated flame retardants, and the matte tin-plated leads meet JESD 201 Class 2 whisker resistance. This designation ensures environmental compliance and long-term solder joint reliability - critical for automotive and industrial applications where regulatory adherence and field longevity are mandatory. P6SMB13AHM3_B/I carries full documentation for both attributes.
What is the standoff voltage (VWM) of P6SMB13AHM3_B/I, and why does it matter?
The standoff voltage (VWM) of P6SMB13AHM3_B/I is 11.1 V - the maximum DC or RMS voltage that can be continuously applied without exceeding 5 µA reverse leakage current. This parameter establishes the safety margin between normal operating voltage and the onset of avalanche conduction. For a nominal 12 V automotive system, VWM = 11.1 V ensures reliable blocking during startup, cranking, and ripple conditions while allowing headroom for transient clamping. P6SMB13AHM3_B/I's VWM is tightly controlled to prevent premature conduction.
How does P6SMB13AHM3_B/I differ from bidirectional variants like P6SMB13CA?
P6SMB13AHM3_B/I is unidirectional, meaning it conducts only in reverse bias (cathode positive) and blocks forward current - ideal for DC power rail protection where polarity is fixed. In contrast, P6SMB13CA is bidirectional and symmetrical, conducting in both directions, suited for AC lines or differential signal pairs. P6SMB13AHM3_B/I has a marked cathode band; P6SMB13CA has no polarity marking. Their VBR and VC values differ due to internal structure - P6SMB13AHM3_B/I's 12.4–13.7 V VBR applies only in reverse, whereas P6SMB13CA's rating spans both polarities.
