Product details
Overview
P6SMB12AHE3_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 12 V standoff voltage (VWM), 16.7 V maximum clamping voltage at 35.9 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB12AHE3_B/H datasheet, P6SMB12AHE3_B/H pinout, P6SMB12AHE3_B/H application, or P6SMB12AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its breakdown threshold of 11.4–12.6 V at 1 mA test current. Its glass-passivated junction ensures stable leakage performance (<5.0 μA at 10.2 V) and fast response time under ESD and lightning-induced surges.
The device complies with J-STD-020 MSL Level 1 (260 °C reflow peak), supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a positive temperature coefficient of VBR (+0.078 %/°C), enabling predictable thermal derating in high-temperature environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the clamping voltage of P6SMB12AHE3_B/H at its rated peak pulse current?
The P6SMB12AHE3_B/H has a maximum clamping voltage (VC) of 16.7 V at 35.9 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value ensures downstream components see limited overvoltage during surge events. The P6SMB12AHE3_B/H maintains this clamping performance across its specified operating temperature range and meets IEC 61000-4-5 surge immunity requirements.
Is P6SMB12AHE3_B/H qualified for automotive applications?
Yes, P6SMB12AHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3_B" suffix per Vishay's ordering nomenclature. It is specifically intended for automotive use cases including engine control units, body electronics, and ADAS sensor modules. The P6SMB12AHE3_B/H undergoes stress testing for temperature cycling, humidity, and mechanical shock per AEC-Q101 standards.
What is the thermal resistance of P6SMB12AHE3_B/H from junction to ambient?
The typical thermal resistance from junction to ambient (RθJA) for P6SMB12AHE3_B/H is 100 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper pads). This value assumes natural convection cooling and informs thermal design margins for sustained power dissipation up to 5.0 W. The P6SMB12AHE3_B/H also has RθJL = 20 °C/W for lead-to-junction conduction paths.
How does the breakdown voltage tolerance of P6SMB12AHE3_B/H affect circuit design?
P6SMB12AHE3_B/H has a breakdown voltage (VBR) range of 11.4–12.6 V at 1 mA test current, representing ±5% tolerance. This tight spread ensures consistent clamping onset across production lots and allows reliable margining against system overvoltage thresholds. When designing with P6SMB12AHE3_B/H, engineers must verify that the 12.6 V upper limit remains below the absolute maximum rating of protected ICs.
What packaging format is supplied for P6SMB12AHE3_B/H?
P6SMB12AHE3_B/H is supplied in 7" diameter plastic tape and reel format (package code "H"), with 750 units per reel. This format supports high-speed pick-and-place assembly and complies with EIA-481 standards. The P6SMB12AHE3_B/H uses matte tin-plated leads and meets J-STD-002 solderability requirements and JESD 22-B102 whisker testing Class 2.
