Product details
Overview
SMB10J17AHM3_A/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 17 V standoff voltage (VWM), 18.9–20.9 V breakdown range (VBR at 1 mA), 1000 W peak pulse power (10/1000 µs), 36.2 A peak pulse current (IPPM), and clamps to ≤27.6 V at rated surge - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J17AHM3_A/H datasheet, SMB10J17AHM3_A/H pinout, SMB10J17AHM3_A/H application, or SMB10J17AHM3_A/H equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that diverts transient energy above its breakdown threshold to ground while maintaining low clamping voltage under 10/1000 µs surges. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), critical for protecting sensitive MOSFET gates and microcontroller I/O pins.
Rated for -55 °C to +150 °C junction temperature and qualified per AEC-Q101, SMB10J17AHM3_A/H supports automotive-grade reliability. Its MSL Level 1 rating (260 °C peak reflow) and matte tin-plated leads meet J-STD-002/JESD 22-B102 solderability standards, enabling robust manufacturing yield in high-volume automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 18.9 V / 20.9 V at 1 mA - guaranteed breakdown onset range; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPPM | ≤27.6 V at 36.2 A - clamping voltage during full-rated 1000 W surge; limits stress on downstream ICs like CAN transceivers or ADC inputs. |
| PPPM | 1000 W (10/1000 µs) - peak surge power handling capacity; supports ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 compliance. |
| IFSM | 100 A (8.3 ms half-sine) - non-repetitive forward surge rating; withstands load-dump events in 12 V automotive electrical systems. |
| Junction Temp | -55 °C to +150 °C - extended thermal range enables under-hood deployment without derating in engine control modules. |
| Package | SMB (DO-214AA) - surface-mount outline with 2.20 mm max height; compatible with standard pick-and-place nozzles and reflow profiles. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; polarity indicated by cathode band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-to-cathode reverse-biased terminal | Connected to protected line (e.g., CAN_H); conducts surge current to ground when VLINE exceeds VBR. |
| Anode (non-banded end) | Reference/ground return path | Connected to system ground plane; completes clamping path with minimal inductance via short, wide copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS sensors - meets stress test requirements for temperature cycling, HTRB, and ESD. |
| Glass passivated junction | Eliminates metal migration and interfacial corrosion risks, ensuring long-term leakage stability (<1.0 µA) over 15-year vehicle lifetime. |
| Low profile SMB package | Max height 2.20 mm - enables compact layout in space-constrained ECUs and camera modules without compromising thermal dissipation. |
| MSL Level 1 rating | Compatible with standard lead-free reflow (peak 260 °C); no baking required prior to assembly, reducing production cost and cycle time. |
| Halogen-free & RoHS-compliant | HM3 suffix confirms halogen-free molding compound and compliant plating - satisfies EU ELV and OEM chemical content requirements. |
Applications
| Automotive Sensor Interface | Industrial PLC Digital Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A-E3/52 | Same VWM/VBR/PPPM, but commercial-grade (non-AEC-Q101), RoHS-compliant only (not halogen-free). | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and halogen-free material is optional. |
| SMB10J17AHM3_B/I | Identical electrical specs and AEC-Q101/halogen-free status; differs only in packaging - 3200-unit 13" reel vs. 750-unit 7" reel. | No functional difference; choice depends solely on production volume and SMT line feeder configuration. | Choose based on procurement scale and assembly line logistics - same performance, same qualification, different reel size. |
Compared with SMB10J17AHM3_A/H, SMBJ17A-E3/52 offers lower cost but excludes automotive qualification and halogen-free compliance, whereas SMB10J17AHM3_B/I delivers identical protection performance with optimized reel quantity for high-volume manufacturing.

FAQ
What is the clamping voltage of SMB10J17AHM3_A/H at its rated peak pulse current?
The SMB10J17AHM3_A/H clamps to a maximum of 27.6 V when subjected to its rated peak pulse current of 36.2 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and ensures downstream components such as 3.3 V or 5 V microcontrollers remain within safe operating voltage limits during surge events. The clamping performance is guaranteed across the full operating temperature range of -55 °C to +150 °C.
Is SMB10J17AHM3_A/H qualified for automotive use?
Yes, SMB10J17AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HM3" (halogen-free, RoHS-compliant, and AEC-Q101 qualified). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making SMB10J17AHM3_A/H suitable for under-hood and cabin applications in passenger vehicles and commercial vehicles.
What does the "HM3" suffix in SMB10J17AHM3_A/H indicate?
The "HM3" suffix in SMB10J17AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., "E3") and confirms compliance with automotive chemical content requirements and environmental standards. The "_A/H" further specifies the revision level and 7" tape-and-reel packaging format (750 units per reel).
Can SMB10J17AHM3_A/H be used in bidirectional signal lines?
No, SMB10J17AHM3_A/H is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection (e.g., RS-485, USB, or AC-coupled lines), Vishay offers the SMB8J17CA series - which shares the same VWM and package but provides symmetrical clamping in both polarities. Using SMB10J17AHM3_A/H on bidirectional lines would result in unintended conduction during negative transients.
What is the thermal resistance of SMB10J17AHM3_A/H, and how does it affect layout design?
SMB10J17AHM3_A/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 safe junction temperatures during repeated surges, PCB layout must provide adequate copper area and thermal vias - especially critical in automotive applications where ambient temperatures exceed 85 °C. Derating curves in the datasheet guide power handling at elevated temperatures.
