Product details
Overview
P6SMB13AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 13 V breakdown voltage (VBR min/max: 12.4–13.7 V at 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 automotive and industrial power supplies.
For engineers reviewing the P6SMB13AHM3_A/H datasheet, P6SMB13AHM3_A/H pinout, P6SMB13AHM3_A/H application, or P6SMB13AHM3_A/H equivalent, this device is selected for robust ESD and surge protection where low-profile SMB (DO-214AA) mounting, AEC-Q101 qualification, halogen-free RoHS compliance, and stable clamping under repetitive transients are required.
Technical Context
The P6SMB13AHM3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage (<5.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with RθJA = 100 °C/W and RθJL = 20 °C/W. The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 18.2 V at 33.0 A - clamped voltage during 600 W transient, limiting stress on downstream components |
| PPPM | 600 W (10/1000 μs waveform) - peak surge energy handling capability under standard test conditions |
| IFSM | 100 A (8.3 ms half-sine) - surge current tolerance for inductive turn-off events without failure |
| TJ max | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Package | SMB (DO-214AA) - low-profile SMD footprint compatible with automated placement and reflow |

Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters after rectification and bulk capacitance. IC Role / Device Role / Timing Role: Standoff-rated TVS across output capacitor to prevent catastrophic failure during no-load overvoltage faults. Use Value: Activates at 11.1 V and clamps to 18.2 V before secondary-side regulator or load reaches destructive thresholds. |
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-E3/52 | Same VWM (11.1 V), identical SMB package, but not AEC-Q101 qualified; higher ID (20 μA vs. 5 μA) | Limited to commercial-grade consumer/industrial use; unsuitable for automotive under-hood deployment | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive qualification needs |
| 1.5SMC13A | Same electrical specs, but larger SMC (DO-214AB) package (5.3 mm × 4.5 mm); 1.5 kW rating (not 600 W) | Higher power handling but requires PCB area increase; thermal performance differs due to larger pad layout | Choose only if system-level surge requirements exceed 600 W or existing layout accommodates SMC footprint |
Compared with SMAJ13A-E3/52 and 1.5SMC13A, P6SMB13AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint in a 600 W TVS - making it the preferred choice for space-constrained, automotive-qualified designs requiring traceable compliance and long-term supply stability.

FAQ
What is the maximum clamping voltage of the P6SMB13AHM3_A/H under a 10/1000 μs surge?
The P6SMB13AHM3_A/H has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and ensures downstream ICs remain below absolute maximum ratings during surge events. The P6SMB13AHM3_A/H achieves this with low incremental surge resistance and fast avalanche response.
Is the P6SMB13AHM3_A/H qualified for automotive applications?
Yes, the P6SMB13AHM3_A/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and documented in Vishay's ordering information. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per automotive standards. The P6SMB13AHM3_A/H is approved for under-hood and body-control module applications where junction temperatures reach up to +150 °C.
What does the "_A/H" suffix in P6SMB13AHM3_A/H signify?
The "_A/H" suffix denotes packaging configuration: "A" indicates the base P6SMB13A device variant (unidirectional, 13 V nominal), and "H" specifies 7-inch plastic tape-and-reel delivery (750 units per reel). The "HM3" portion confirms halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The P6SMB13AHM3_A/H is therefore a fully compliant, automotive-grade, surface-mount TVS in standard SMB packaging.
How does the P6SMB13AHM3_A/H compare to bidirectional TVS diodes like P6SMB13CA?
The P6SMB13AHM3_A/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V rail to GND), offering lower leakage (<5 μA at VWM) and tighter VBR tolerance than its bidirectional counterpart P6SMB13CA. The P6SMB13CA supports AC or floating signal lines but exhibits higher leakage and symmetric clamping in both directions. Selection depends on circuit topology - the P6SMB13AHM3_A/H is optimal for polarized power rails.
What is the thermal resistance from junction to ambient for the P6SMB13AHM3_A/H?
The P6SMB13AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air convection and is critical for calculating safe power derating above 25 °C ambient. For higher-power or elevated-temperature operation, the P6SMB13AHM3_A/H benefits from additional copper pour or thermal vias to reduce effective RθJA.
