Product details
Overview
P6SMB16AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM), 22.5 V clamping voltage (VC) at 26.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and automotive electronics.
For engineers reviewing the P6SMB16AHM3_A/H datasheet, P6SMB16AHM3_A/H pinout, P6SMB16AHM3_A/H application, or P6SMB16AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds the breakdown threshold (VBR = 15.2–16.8 V at 1 mA), it avalanches to divert transient energy away from downstream circuitry. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads, P6SMB16AHM3_A/H delivers 600 W peak pulse power handling with 0.01% duty cycle, thermal resistance RθJA = 100 °C/W, and junction temperature range from –65 °C to +150 °C - enabling robust operation in automotive under-hood and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC bias margin. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - precise avalanche initiation range ensuring predictable clamping onset. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 26.7 A - peak voltage seen by protected circuit during full-rated 10/1000 μs surge. |
| PPPM (Peak Pulse Power) | 600 W - transient energy-handling capacity per JEDEC standard waveform; determines survivability of common lightning/inductive spikes. |
| ID (Max Reverse Leakage) | 1.0 μA at VWM - ultra-low leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | +150 °C - enables use in high-temperature automotive and industrial enclosures without derating. |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and J-STD-020 MSL Level 1 rating. |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with matte tin-plated leads, 0.220" × 0.205" outline, cathode indicated by band on body end. Compliant with UL 94 V-0 flammability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (unidirectional) | Connected to ground or lower-potential rail; completes shunt path during reverse transient. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line; avalanche conduction initiates here when VLINE > VBR. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5B | Same VWM (13.6 V), VC = 25.5 V at 23.5 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required. | Select when board space is constrained and surge threat level is below IEC 61000-4-5 Level 3. |
| 1.5SMC16A | Same electrical specs (VWM = 13.6 V, VC = 22.5 V), but SMC (DO-214AB) package - 20 % larger footprint, RθJA = 60 °C/W. | Better thermal dissipation in high-ambient environments; requires more PCB area and different stencil design. | Choose for industrial power supplies where sustained surge repetition demands superior heat spreading. |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, P6SMB16AHM3_A/H offers optimal balance of 600 W surge capability, SMB footprint compatibility, AEC-Q101 qualification, and halogen-free compliance - making it preferred for space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the clamping voltage of P6SMB16AHM3_A/H at its rated peak pulse current?
The clamping voltage (VC) of P6SMB16AHM3_A/H is 22.5 V when subjected to its maximum peak pulse current (IPPM) of 26.7 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The low VC ensures sensitive downstream components like microcontrollers and interface ICs remain within safe operating limits.
Is P6SMB16AHM3_A/H qualified for automotive applications?
Yes, P6SMB16AHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's P6SMB series datasheet (Document Number: 88370, Revision: 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and surge robustness - validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and sensor signal conditioning circuits.
What does the "HM3" suffix indicate in P6SMB16AHM3_A/H?
The "HM3" suffix in P6SMB16AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates the packaging format (7" tape and reel), "M3" confirms halogen-free molding compound and lead finish, and the underscore "_A/H" specifies revision A in that tape-and-reel configuration. This suffix ensures compliance with automotive environmental standards and eliminates brominated flame retardants without sacrificing electrical or thermal performance.
How does P6SMB16AHM3_A/H differ from bidirectional variants like P6SMB16CA?
P6SMB16AHM3_A/H is unidirectional, featuring a cathode band for polarity-sensitive placement and optimized for DC-biased lines such as power rails or single-ended signal paths. In contrast, P6SMB16CA is bidirectional with symmetrical clamping in both directions and no polarity marking - suited for AC-coupled or differential lines like RS-485 or Ethernet. Their VWM (13.6 V vs. 13.6 V), VBR (15.2–16.8 V vs. 15.2–16.8 V), and VC (22.5 V vs. 22.5 V) are identical, but circuit topology and layout constraints differ significantly.
What is the maximum operating junction temperature for P6SMB16AHM3_A/H?
The maximum operating junction temperature (TJ max) for P6SMB16AHM3_A/H is +150 °C, as specified in the Absolute Maximum Ratings table of the Vishay P6SMB datasheet. This rating allows reliable operation in high-ambient environments such as automotive engine compartments or industrial motor drives. Derating curves in Figure 2 confirm usable power dissipation down to zero at 150 °C ambient when mounted on recommended 0.2" × 0.2" copper pads.
