Product details
Overview
P6SMB15AHM3_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 15 V breakdown voltage (VBR = 14.3–15.8 V at IT = 1.0 mA), 12.8 V stand-off voltage (VWM), and 21.2 V maximum clamping voltage (VC) at 28.3 A peak pulse current (IPPM), delivering 600 W peak pulse power with 10/1000 μs waveform - ideal for protecting MOSFETs and ICs in automotive and industrial power rails.
For engineers reviewing the P6SMB15AHM3_B/H datasheet, P6SMB15AHM3_B/H pinout, P6SMB15AHM3_B/H application, or P6SMB15AHM3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 rating, and verified clamping performance under repetitive surge conditions per JESD22-B102 and J-STD-020.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable reverse leakage (<1.0 μA at VWM) and fast response time (<1.0 ns). Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (−65 to +150 °C) support reliable operation in high-temperature automotive environments.
The device meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when applied with proper PCB layout - including 0.2" × 0.2" copper pads per terminal - and delivers consistent 600 W surge capability at ≤0.01% duty cycle without degradation under repetitive 10/1000 μs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA test current - defines precise voltage threshold where clamping begins |
| VWM | 12.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 21.2 V at 28.3 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| IPPM | 28.3 A with 10/1000 μs waveform - quantifies surge current handling capacity under standardized test condition |
| PPPM | 600 W - peak pulse power rating enabling robust protection against inductive switching spikes |
| TJ max. | +150 °C - supports under-hood automotive use and industrial ambient temperature extremes |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to ±35 V and ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges before they reach MCU or CAN transceiver inputs. Use Value: Limits voltage to 21.2 V during 28.3 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V logic interfaces. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at connector entry point to shunt fast transients before reaching ADC front-end or op-amp buffer. Use Value: Sub-1 ns response ensures clamping occurs before sensitive analog circuitry experiences overvoltage stress. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feed Protection |
|
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters subjected to lightning-induced surges on output lines. IC Role / Device Role / Timing Role: Standoff-rated TVS (12.8 V) placed across regulated 12 V output to absorb energy from transformer leakage spikes. Use Value: 600 W rating sustains multiple 10/1000 μs events without degradation, extending adapter field life. |
Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras) from induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Unidirectional TVS connected between power pair and chassis ground to divert common-mode transients. Use Value: AEC-Q101 qualification ensures reliability in outdoor telecom enclosures exposed to wide temperature swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/52 | Same VBR range (14.3–15.8 V), but SMA package (smaller footprint, higher RθJA = 140 °C/W), non-AEC-Q101, commercial grade only | Limited to consumer/industrial use; not qualified for automotive under-hood deployment | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC15A | Same electrical specs, but SMC (DO-214AB) package - larger footprint, lower RθJA (80 °C/W), same AEC-Q101 availability via HM3 suffix | Better thermal performance for high-duty-cycle surge environments; requires more PCB area | Choose when enhanced thermal dissipation is required and layout allows larger package |
Compared with SMAJ15A-E3/52, P6SMB15AHM3_B/H offers automotive qualification and superior thermal margin in SMB form factor; versus 1.5SMC15A, it trades some thermal headroom for compactness while retaining AEC-Q101 compliance and identical clamping behavior.

FAQ
What is the clamping voltage of P6SMB15AHM3_B/H at its rated peak pulse current?
The P6SMB15AHM3_B/H has a maximum clamping voltage (VC) of 21.2 V at 28.3 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methodology and ensures downstream components experience no more than 21.2 V during surge events. The P6SMB15AHM3_B/H maintains this clamping performance across its specified operating temperature range and after repeated surge exposures.
Is P6SMB15AHM3_B/H qualified for automotive applications?
Yes, P6SMB15AHM3_B/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024, Doc. #88370). The HM3 designation indicates halogen-free, RoHS-compliant construction with full automotive reliability testing - including temperature cycling, high-temperature reverse bias, and ESD - making P6SMB15AHM3_B/H suitable for engine control, body electronics, and ADAS subsystems.
What does the "_B/H" suffix mean in P6SMB15AHM3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB15A base part, while "/H" specifies packaging in 7-inch plastic tape and reel with 750 units per reel. This ordering code format aligns with Vishay's standardized nomenclature: HM3 confirms halogen-free RoHS compliance, _B confirms automotive qualification, and /H identifies the delivery format. P6SMB15AHM3_B/H is thus a fully traceable, automotive-grade, surface-mount TVS diode ready for high-volume SMT assembly.
How does P6SMB15AHM3_B/H compare to bidirectional TVS diodes like P6SMB15CA?
P6SMB15AHM3_B/H is unidirectional and intended for DC power line protection where polarity is fixed, offering lower leakage (<1.0 μA at 12.8 V) and tighter VBR tolerance. In contrast, P6SMB15CA is bidirectional and suited for AC or floating signal lines, with symmetrical clamping in both directions but higher leakage at equivalent voltages. P6SMB15AHM3_B/H cannot substitute for P6SMB15CA in AC-coupled applications due to polarity dependence and asymmetric behavior.
What is the maximum operating junction temperature for P6SMB15AHM3_B/H?
The maximum operating junction temperature (TJ) for P6SMB15AHM3_B/H is +150 °C, as specified in the Absolute Maximum Ratings table of the Vishay P6SMB datasheet. This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in Figure 2 confirm usable power dissipation down to ambient temperatures of +125 °C when mounted per recommended pad layout.
