Product details
Overview
P6SMB16AHM3_B/I 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 13.6 V stand-off voltage (VWM), 16.8 V maximum breakdown voltage (VBR), 22.5 V clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6SMB16AHM3_B/I datasheet, P6SMB16AHM3_B/I pinout, P6SMB16AHM3_B/I application, or P6SMB16AHM3_B/I equivalent, key selection criteria include its 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 unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior under repetitive transient stress. Its thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W support reliable operation up to 150 °C junction temperature when mounted per recommended pad layout.
The device delivers fast response time (<1 ps typical) and low clamping ratio (VC/VBR ≈ 1.34), enabling effective protection of downstream MOSFETs and ICs against ESD, lightning-induced surges, and inductive switching spikes. It meets MSL Level 1 per J-STD-020 with 260 °C reflow peak and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush and fault-current tolerance |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood and high-ambient industrial enclosures |
| Package | SMB (DO-214AA) - Low-profile SMT footprint (4.57 mm × 3.94 mm × 2.20 mm) optimized for automated assembly and board space efficiency |
Pinout & Package

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between signal line and chassis ground to limit transient voltage before it reaches the transceiver input stage. Use Value: Maintains signal integrity during 12 V/24 V system transients by clamping to ≤22.5 V, preventing latch-up or damage to 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing inductive kickback energy before it propagates into optocoupler or microcontroller input circuitry. Use Value: Enables >100,000 surge cycles at rated 600 W without parameter shift, reducing field failure rates in harsh electromagnetic environments. |
| Consumer Power Adapter Output | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side overvoltage suppression on 5 V/12 V USB-C PD and AC/DC adapter outputs subject to capacitor discharge and hot-plug transients. IC Role / Device Role / Timing Role: Fast-clamping unidirectional TVS placed across output rails to shunt surge energy away from downstream USB port controllers and load switches. Use Value: Limits output rail overshoot to 22.5 V during 10/1000 μs events, preserving compliance with USB-IF voltage tolerance specs and preventing connected device damage. |
Use Scenario: Primary protection for Ethernet PHY and DSL line drivers against lightning-induced surges entering via RJ-45 jacks in residential gateways and base stations. IC Role / Device Role / Timing Role: First-stage TVS on differential pairs, coordinated with GDTs and common-mode chokes to divert common-mode surge energy before differential-mode filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5B | Same VWM (13.6 V) and VC (22.5 V), but lower PPPM (400 W) and non-AEC-Q101 rated | Restricted to commercial-grade consumer and computing applications; not qualified for automotive use | Select when cost sensitivity outweighs automotive qualification requirements and surge energy is limited to ≤400 W |
| 1.5SMC16A | Same electrical specs but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher RθJA (60 °C/W) | Requires more PCB area and exhibits slower thermal recovery; suitable where layout space permits and higher surge margin is needed | Choose when legacy SMC footprint compatibility is required or when derated 1.5 kW peak power (per Vishay 1.5SMC spec) is needed with heatsinking |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, P6SMB16AHM3_B/I uniquely combines AEC-Q101 qualification, SMB footprint compactness, and full 600 W surge capability - making it the preferred choice for space-constrained automotive and industrial designs requiring production-grade reliability.

FAQ
What is the clamping voltage of P6SMB16AHM3_B/I at its rated peak pulse current?
The P6SMB16AHM3_B/I has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured using the standardized 10/1000 μs double-exponential waveform. This value ensures protected circuits remain within safe voltage limits during surge events, and is confirmed in the Vishay P6SMB datasheet revision 09-Jan-2024, page 2.
Is P6SMB16AHM3_B/I qualified for automotive applications?
Yes, P6SMB16AHM3_B/I is AEC-Q101 qualified, as indicated by the "HM3_B" suffix per Vishay's ordering nomenclature (page 3, Note 1). It is specifically intended for automotive use cases including sensor interfaces, body control modules, and infotainment power rails, and undergoes stress testing per the AEC-Q101 standard for discrete semiconductors.
What does the "HM3_B/I" suffix mean in P6SMB16AHM3_B/I?
In P6SMB16AHM3_B/I, "HM3" denotes halogen-free and RoHS-compliant construction; "B" indicates AEC-Q101 qualification for the 6.8 V–220 V unidirectional/bidirectional range; and "I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms compliance, qualification, and logistics configuration per Vishay's ordering information table (page 3).
Can P6SMB16AHM3_B/I be used in bidirectional configurations?
No, P6SMB16AHM3_B/I is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and its specified polarity: cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB16CA), and exhibit symmetrical breakdown in both directions - a functionality not supported by the P6SMB16AHM3_B/I device.
What is the thermal resistance of P6SMB16AHM3_B/I, and how does it affect layout design?
P6SMB16AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. This value mandates adherence to Vishay's pad layout guidelines (page 5) to ensure safe operation at 150 °C junction temperature - undersized pads will cause thermal derating and premature failure under sustained surge conditions.
