Product details
Overview
P6SMB13AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps transients to ≤18.2 V at 33.0 A peak pulse current (10/1000 µs), delivering 600 W peak pulse power in automotive and industrial signal-line protection.
For engineers reviewing the P6SMB13AHM3/H datasheet, P6SMB13AHM3/H pinout, P6SMB13AHM3/H application, or P6SMB13AHM3/H equivalent, this device is selected for high-reliability transient suppression on DC power rails and low-voltage sensor interfaces where AEC-Q101 qualification, halogen-free RoHS compliance, and SMB (DO-214AA) package compatibility are required.
Technical Context
The P6SMB13AHM3/H operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to ESD and surge events while maintaining low incremental surge resistance. Its thermal resistance (RθJA = 100 °C/W) and maximum junction temperature of 150 °C support operation in thermally constrained PCB layouts without forced cooling.
Designed for repetitive 10/1000 µs waveform surges at 0.01% duty cycle, it delivers stable clamping performance across -65 °C to +150 °C ambient range. The cathode-band polarity marking and matte tin-plated leads ensure compatibility with J-STD-002 soldering and JESD22-B102 reliability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA test current - defines precise avalanche onset threshold for predictable clamping initiation |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA, ensuring no false triggering |
| VC @ IPPM | ≤18.2 V at 33.0 A - clamping voltage under full 600 W surge, limiting downstream IC stress to safe levels |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 µs waveform, supporting IEC 61000-4-5 Level 4 compliance |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine), enabling protection against inductive switch-off spikes |
| TJ max | +150 °C - extended junction temperature rating allows use in under-hood automotive and industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.130" footprint, optimized for automated placement |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102; cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; enables unidirectional clamping to ground when cathode is tied to rail |
| Cathode | Avalanche conduction terminal | Marked with band; connected to higher-potential side (e.g., VCC or signal line); conducts during overvoltage to shunt energy to reference |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces under stress conditions |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for global OEM supply chains without compromising surge robustness |
| 600 W peak pulse power | Handles high-energy transients such as ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Combination Wave surges |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or damage to downstream 12 V logic |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without moisture sensitivity concerns, eliminating bake-out steps in production |

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 VBR range (12.4–13.7 V) but lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Lower surge capacity limits use to consumer-grade or non-automotive applications with reduced threat severity | Select when board space is critical and surge exposure is limited to IEC 61000-4-2 ESD only, not full IEC 61000-4-5 surges |
| 1.5SMC13A | Same electrical specs but SMC (DO-214AB) package - 20% larger footprint, lower RθJA = 85 °C/W, same AEC-Q101 option available | Better thermal performance supports higher repetition rates in industrial motor drives with frequent switching noise | Choose when thermal management is prioritized over compactness, especially in high-ambient-temperature enclosures |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHM3/H uniquely balances automotive qualification, halogen-free compliance, and SMB footprint - making it optimal for space-constrained AEC-Q101 designs where 600 W surge immunity and MSL Level 1 reflow are mandatory.

FAQ
What is the maximum clamping voltage of the P6SMB13AHM3/H under surge conditions?
The P6SMB13AHM3/H clamps to a maximum of 18.2 V when subjected to its rated 33.0 A peak pulse current (10/1000 µs waveform). This value is measured per standard test conditions in the Vishay datasheet (Document Number 88370, Rev. 09-Jan-2024) and represents the upper limit of voltage seen by downstream circuitry during a full 600 W transient event. Designers must verify that this clamping level remains below the absolute maximum ratings of protected components.
Is the P6SMB13AHM3/H qualified for automotive applications?
Yes, the P6SMB13AHM3/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix indicating halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It meets the stress test requirements for temperature cycling, humidity bias, and mechanical shock defined in AEC-Q101, making it suitable for under-hood and cabin electronics including body control modules and ADAS sensor interfaces.
What does the "H" in P6SMB13AHM3/H signify in the ordering code?
The "H" in P6SMB13AHM3/H denotes the packaging configuration: 7-inch diameter plastic tape and reel, with a base quantity of 750 units per reel. This format is optimized for high-volume SMT assembly lines using standard pick-and-place equipment, and aligns with IPC-7351 land pattern recommendations for the SMB (DO-214AA) package used by the P6SMB13AHM3/H.
How does the P6SMB13AHM3/H differ from bidirectional variants like P6SMB13CA?
The P6SMB13AHM3/H is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where current flows in one direction. In contrast, P6SMB13CA is bidirectional - lacking polarity marking and capable of clamping both positive and negative transients - making it suitable for AC signal lines or differential buses. Their VBR, VWM, and VC values differ accordingly, and they are not interchangeable without circuit redesign.
What is the thermal resistance and maximum junction temperature of the P6SMB13AHM3/H?
The P6SMB13AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum operating junction temperature (TJ) of +150 °C. These values are specified in the Thermal Characteristics table of the Vishay datasheet and enable reliable operation in high-temperature environments such as automotive engine compartments or sealed industrial enclosures without active cooling.
