Product details
Overview
P6SMB13AHM3_A/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 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), 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 industrial power supplies.
For engineers reviewing the P6SMB13AHM3_A/I datasheet, P6SMB13AHM3_A/I pinout, P6SMB13AHM3_A/I application, or P6SMB13AHM3_A/I equivalent, this device delivers verified AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and low incremental surge resistance for robust ESD and lightning surge protection in automotive and industrial environments.
Technical Context
The P6SMB13AHM3_A/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and fast response (<1 ns). Its clamping action begins at VWM = 11.1 V and limits transient voltages to ≤18.2 V under 33.0 A 10/1000 μs pulses, with thermal resistance RθJA = 100 °C/W enabling operation up to TJ = +150 °C.
Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. The cathode band denotes polarity, and its SMB package supports 0.2" × 0.2" copper pad layout per Vishay's recommended footprint.
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 range for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 18.2 V at 33.0 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W with 10/1000 μs waveform - sustains high-energy surges common in automotive load-dump and inductive switching |
| IFSM | 100 A (8.3 ms half-sine) - handles single-event surge currents without bond-wire failure |
| TJ max. | +150 °C - enables use in under-hood automotive modules and high-ambient industrial enclosures |
| Package | SMB (DO-214AA) - standardized 2-pin surface-mount outline with 2.20 mm height and 3.94 mm length for compact PCB layouts |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load-dump transients up to 35 V and ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input, clamping surges before they reach regulator ICs. Use Value: Limits peak voltage to ≤18.2 V during 33 A transients, preventing damage to 24 V-tolerant PMICs and microcontrollers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting fast transients away from op-amp input stages and ADC front-ends. Use Value: Sub-1 ns response ensures clamping occurs before sensitive analog circuitry experiences destructive overvoltage. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
Use Scenario: Safeguarding PoE-powered Ethernet switch ports from induced lightning surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Primary TVS on 48 V DC input bus, coordinated with secondary GDT or MOV for multi-stage protection. Use Value: 600 W rating absorbs energy from IEC 61000-4-5 Combination Wave (1.2/50 μs & 8/20 μs) without degradation. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters after rectification, before bulk capacitor and controller IC. IC Role / Device Role / Timing Role: Clamps switching spikes and line transients on 12–24 V output rails feeding USB-C PD or display logic. Use Value: 11.1 V VWM allows normal operation while blocking noise; 18.2 V VC prevents latch-up in downstream LDOs. |
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 SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-power applications due to reduced thermal mass; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC13A | Same electrical specs, but larger SMC (DO-214AB) package with higher power handling margin and RθJA = 70 °C/W | Better suited for high-reliability industrial systems requiring extended surge endurance beyond 600 W | Choose for designs needing enhanced thermal performance or legacy SMC footprint compatibility |
Compared with P6SMB13AHM3_A/I, SMAJ13A-E3/5B trades automotive qualification and thermal robustness for smaller size, while 1.5SMC13A offers superior heat dissipation at the cost of PCB area - making P6SMB13AHM3_A/I the optimal balance of AEC-Q101 compliance, SMB footprint, and 600 W surge capability.

FAQ
What is the maximum clamping voltage of the P6SMB13AHM3_A/I under rated surge conditions?
The P6SMB13AHM3_A/I exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 33.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures downstream components see no more than 18.2 V during transient events - critical for safeguarding 13.5 V–16 V tolerant ICs in automotive and industrial applications. The P6SMB13AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the P6SMB13AHM3_A/I qualified for automotive applications?
Yes, the P6SMB13AHM3_A/I carries the HM3 suffix, indicating halogen-free, RoHS-compliant construction and full AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D. This makes the P6SMB13AHM3_A/I suitable for under-hood and chassis-mounted automotive modules where reliability under thermal and mechanical stress is essential. The P6SMB13AHM3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "_A/I" suffix signify in P6SMB13AHM3_A/I?
The "_A/I" suffix in P6SMB13AHM3_A/I indicates packaging configuration: "A" denotes the standard revision level per Vishay's internal documentation, and "I" specifies 13-inch diameter plastic tape-and-reel delivery containing 3200 units. This format supports high-volume SMT assembly with industry-standard feeder compatibility. The base "HM3" confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - all attributes verified in the official Vishay datasheet document 88370.
How does the P6SMB13AHM3_A/I compare to bidirectional TVS diodes like P6SMB13CA?
The P6SMB13AHM3_A/I is unidirectional, meaning it protects only against positive transients on the cathode side relative to anode (ground), whereas P6SMB13CA is bidirectional and suppresses surges of either polarity. Unidirectional devices like the P6SMB13AHM3_A/I offer lower leakage current and tighter VBR tolerance - advantageous in DC power rail protection. The P6SMB13AHM3_A/I cannot replace P6SMB13CA in AC-coupled or floating signal line applications without circuit redesign.
What is the thermal resistance and maximum junction temperature for the P6SMB13AHM3_A/I?
The P6SMB13AHM3_A/I 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. This allows sustained operation in high-ambient environments such as engine control units or industrial motor drives. Derating curves in the Vishay datasheet show usable power capability down to ~3.5 W at 100 °C ambient - a key design parameter confirmed for the P6SMB13AHM3_A/I in Document Number 88370.
