Product details
Overview
P6SMB11AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 11 V breakdown voltage (VBR = 10.5–11.6 V at IT = 1.0 mA), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power supplies.
For engineers reviewing the P6SMB11AHM3_A/H datasheet, P6SMB11AHM3_A/H pinout, P6SMB11AHM3_A/H application, or P6SMB11AHM3_A/H equivalent, this device is selected for robust overvoltage protection where low clamping voltage, fast response time, AEC-Q101 qualification, halogen-free RoHS compliance, and stable thermal performance up to 150 °C junction temperature are required.
Technical Context
The P6SMB11AHM3_A/H operates as a unidirectional avalanche diode with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its 10/1000 μs waveform rating reflects standardized transient immunity testing per REA definitions, with derating above 25 °C ambient per Fig. 2.
Thermal design relies on RθJA = 100 °C/W (typical, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, enabling reliable operation under repetitive surge conditions at ≤0.01% duty cycle. The device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications

Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) and ISO 7637-2 pulses on 12 V battery-fed ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive-going surges before they reach LDOs or microcontrollers. Use Value: Limits rail voltage to ≤15.6 V during 38.5 A transients, preventing latch-up or permanent damage to downstream 5 V tolerant components. |
Use Scenario: Protecting analog outputs (e.g., 4–20 mA current loops) and digital I/O (CAN, LIN) from ESD and inductive kickback in factory automation PLC modules. IC Role / Device Role / Timing Role: Point-of-entry TVS on sensor interface PCB traces, positioned adjacent to connector to shunt surge energy before reaching signal conditioning ICs. Use Value: Responds in <1 ps to sub-nanosecond ESD events and clamps to 15.6 V, preserving signal integrity and avoiding false triggering in precision measurement circuits. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feeding Protection |
|
Use Scenario: Safeguarding AC/DC adapter primary-side controllers and secondary-side rectifiers against lightning-induced surges entering via mains input. IC Role / Device Role / Timing Role: Secondary-side unidirectional TVS across output capacitor terminals to absorb reflected transients from primary-side MOV failure or line spikes. Use Value: Withstands 600 W surges without degradation, maintaining output regulation and preventing catastrophic failure of downstream USB-PD or QC controllers. |
Use Scenario: Protecting PoE-powered devices (e.g., IP cameras, wireless APs) from voltage reversals and surges on 48 V DC feeding lines. IC Role / Device Role / Timing Role: TVS mounted across DC input pins of PD controller ICs to clamp reverse-polarity connection errors and Ethernet-coupled transients. Use Value: Clamps reverse voltage to ≤15.6 V while blocking normal 48 V operation (VWM = 9.4 V ensures no leakage during steady-state), enabling safe hot-plug operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/52 | Same VBR range (10.5–11.6 V), but lower PPPM = 400 W and higher VC = 18.2 V at 22.9 A; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Less robust for high-energy automotive load-dump events; better suited for space-constrained consumer electronics with lower surge risk | Select when board area is constrained and surge threat level is moderate (e.g., USB peripherals vs. engine control modules) |
| 1.5SMC11A | Same VBR and VC, but SMC package (DO-214AB); higher IFSM = 200 A and PPPM = 1500 W; non-AEC-Q101, commercial grade only | Higher surge margin for industrial motor drives; lacks automotive qualification and halogen-free certification | Choose for cost-sensitive industrial power supplies where AEC-Q101 and RoHS halogen-free compliance are not mandated |
Compared with SMAJ11A-E3/52 and 1.5SMC11A, the P6SMB11AHM3_A/H delivers balanced performance: AEC-Q101 + halogen-free compliance for automotive use, 600 W capability sufficient for ISO 7637-2 Pulse 5a, and SMB footprint offering better thermal dissipation than SMA while remaining smaller than SMC - making it optimal for next-generation compact, certified automotive modules.
