Product details
Overview
SMB10J16AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR at 1 mA), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (10/1000 µs waveform), targeting automotive and industrial power rail protection.
For engineers reviewing the SMB10J16AHM3/H datasheet, SMB10J16AHM3/H pinout, SMB10J16AHM3/H application, or SMB10J16AHM3/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS diode supports robust ESD and lightning surge immunity in 12 V and 24 V systems - especially where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 16 V; when transients exceed VBR (min. 17.8 V), it avalanches to clamp voltage to ≤26.0 V at 38.5 A. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for surface-mount automation, SMB10J16AHM3/H uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. Thermal resistance is 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC bias margin for 12 V nominal rails. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - precise avalanche onset range ensuring consistent turn-on across production lots. |
| VC @ IPPM | 26.0 V at 38.5 A - clamping voltage during 10/1000 µs surge; limits downstream IC stress below 26 V. |
| PPPM | 1000 W - peak pulse power handling capacity; sustains 1 kV/100 A surges per ISO 7637-2 Pulse 1/2/5a. |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); protects against load dump in automotive battery lines. |
| TJ max | +150 °C - maximum junction temperature; enables use in under-hood automotive modules and industrial enclosures. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD (HBM ≥8 kV, CDM ≥1 kV). |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile (max height 2.20 mm), with cathode band marking on terminal D (cathode). Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry / surge return path | Connected to protected line (e.g., 12 V rail); conducts during positive transients when cathode is biased higher. |
| Cathode (K) | Clamping reference / surge sink | Marked by color band; tied to ground or lower-potential rail; provides low-impedance path to divert surge energy. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units, body controllers, and ADAS sensors. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets automotive environmental standards (e.g., ELV, IMDS) without compromising surge performance. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage exposure to downstream MOSFETs, MCUs, and CAN transceivers during surge events. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow assembly without pre-baking or special handling. |
| Glass-passivated junction | Ensures stable VBR, low leakage drift over temperature, and long-term reliability in humid environments. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

IC Role / Device Role / Timing Role: Primary surge suppression element upstream of DC-DC converters and PMICs. Use Value: Absorbs 1000 W pulses without degradation, preserving converter efficiency and reducing need for secondary clamping stages. |
Use Scenario: Overvoltage protection on VBUS line of USB-C ports in portable monitors and docking stations. IC Role / Device Role / Timing Role: Stand-off clamp preventing >20 V from reaching USB PD controller during hot-plug or adapter fault.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM/VBR/VC specs but commercial-grade (non-AEC-Q101), RoHS-compliant only (not halogen-free). | Lacks automotive qualification; suitable for industrial/commercial power supplies but not under-hood automotive use. | Select when AEC-Q101 is not required and cost sensitivity outweighs environmental compliance needs. |
| SMCJ16A-HM3 | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC; thermal resistance RθJA = 35 °C/W. | Better thermal performance for sustained surge duty cycles; requires larger PCB footprint (7.11 mm × 6.22 mm vs. SMB's 4.57 mm × 3.94 mm). | Select when system-level surge testing exceeds 1000 W or board layout allows larger package for improved thermal margin. |
Compared with SMBJ16A-E3/52 and SMCJ16A-HM3, SMB10J16AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it optimal for space-constrained, automotive-grade 12 V rail protection where regulatory compliance and reflow compatibility are mandatory.

FAQ
What is the clamping voltage of SMB10J16AHM3/H at its rated peak pulse current?
The SMB10J16AHM3/H has a maximum clamping voltage (VC) of 26.0 V at 38.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 26.0 V during a full-rated surge event, making SMB10J16AHM3/H suitable for protecting 24 V tolerant interfaces and 3.3 V/5 V logic with appropriate series impedance.
Is SMB10J16AHM3/H qualified for automotive applications?
Yes, SMB10J16AHM3/H is AEC-Q101 qualified - verified for high-temperature operating life, temperature cycling, unbiased HAST, and ESD (HBM ≥8 kV). The "HM3" suffix confirms halogen-free, RoHS-compliant construction meeting automotive material requirements. This makes SMB10J16AHM3/H appropriate for engine control, body electronics, and ADAS modules where reliability under thermal and mechanical stress is mandatory.
What does the "HM3" suffix indicate in SMB10J16AHM3/H?
The "HM3" suffix in SMB10J16AHM3/H denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance, and AEC-Q101 qualification. It distinguishes this variant from commercial-grade "E3" or "M3" versions and confirms compliance with automotive environmental standards (e.g., ELV Directive) without sacrificing electrical performance - critical for Tier 1 suppliers and OEM-approved BOMs.
Can SMB10J16AHM3/H be used in bidirectional protection circuits?
No - SMB10J16AHM3/H is a unidirectional TVS diode, intended for DC-biased lines like positive power rails. For bidirectional protection (e.g., AC lines or data buses), Vishay offers the SMB8J16CA variant with symmetrical breakdown. Using SMB10J16AHM3/H in reverse-biased configurations risks permanent damage due to lack of reverse avalanche capability; always verify polarity alignment in schematic and layout.
What is the thermal resistance of SMB10J16AHM3/H, and how does it affect PCB layout?
SMB10J16AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤150 °C under full 1000 W surge, designers must ensure adequate copper area and avoid thermal bottlenecks - undersized pads or thin FR-4 will elevate junction temperature and reduce surge endurance. Layout should follow Vishay's recommended pad dimensions (0.086" × 0.220") for rated performance.
