Product details
Overview
P6SMB13AHM3_B/H 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 min/max = 12.4 V / 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_B/H datasheet, P6SMB13AHM3_B/H pinout, P6SMB13AHM3_B/H application, or P6SMB13AHM3_B/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS diode delivers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The P6SMB13AHM3_B/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), supporting reliable operation up to TJ = +150 °C. The cathode band marking identifies polarity, and the device meets JESD201 Class 2 whisker resistance.
Key Specifications

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 (12.4–13.7 V), but SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-power consumer applications due to reduced thermal mass and pulse rating margin | Select when board space is constrained and peak surge duty cycle is <0.005 % |
| 1.5SMC13A | Same electrical specs, but SMC (DO-214AB) package - larger body, lower RθJA = 75 °C/W, higher IPPM margin | Better suited for industrial motor drives where sustained surge repetition occurs | Choose when thermal derating above 85 °C ambient is required or higher IFSM (200 A) is needed |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHM3_B/H offers optimal balance of AEC-Q101 qualification, SMB footprint compatibility, and 600 W pulse handling - making it the preferred choice for automotive and mid-tier industrial designs requiring validated reliability and standard assembly processes.

FAQ
What is the exact breakdown voltage range for P6SMB13AHM3_B/H?
The P6SMB13AHM3_B/H has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at a test current of 1.0 mA, measured per ANSI/IEEE C62.35. This tight VBR tolerance ensures repeatable clamping onset across production lots and temperature extremes, and is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88370). The P6SMB13AHM3_B/H maintains this specification under standard test conditions and supports design margining for worst-case transient scenarios.
Is P6SMB13AHM3_B/H AEC-Q101 qualified, and what does the "_B/H" suffix indicate?
Yes, P6SMB13AHM3_B/H is AEC-Q101 qualified - the "_B" denotes AEC-Q101 qualification for the P6SMB6.8A–P6SMB220A voltage range, and "/H" specifies 7" plastic tape-and-reel packaging (750 units per reel). The "HM3" suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance. This qualification is documented in Vishay's ordering information table (page 3, Document 88370), and applies specifically to the P6SMB13AHM3_B/H variant - not generic to the full P6SMB family.
What is the maximum clamping voltage of P6SMB13AHM3_B/H under surge conditions?
The P6SMB13AHM3_B/H exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 33.0 A using the standardized 10/1000 μs waveform. This value is measured at TA = 25 °C with specified PCB mounting (0.2" × 0.2" copper pads per terminal), and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB13AHM3_B/H achieves this with minimal overshoot due to its low incremental surge resistance and fast avalanche response.
Can P6SMB13AHM3_B/H be used in bidirectional configurations?
No, P6SMB13AHM3_B/H is strictly unidirectional - indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB13CA). The P6SMB13AHM3_B/H conducts only in reverse bias above VBR; forward conduction follows standard diode behavior with VF ≈ 3.5 V at 50 A. Using it in bidirectional applications would leave positive-going transients unprotected, so designers must select P6SMB13CA or equivalent for symmetrical surge suppression.
What is the thermal resistance and maximum operating temperature of P6SMB13AHM3_B/H?
The P6SMB13AHM3_B/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 junction-to-lead resistance (RθJL) of 20 °C/W. Its absolute maximum junction temperature is +150 °C, with storage temperature spanning −65 °C to +150 °C. These ratings are validated per JEDEC standards and enable reliable operation in under-hood automotive and industrial enclosures where ambient temperatures exceed 85 °C - a key design parameter confirmed for the P6SMB13AHM3_B/H in Vishay's thermal characteristics table (page 3, Doc. 88370).
