Product details
Overview
SMB10J13AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V clamping voltage (VC) at 46.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the SMB10J13AHM3_A/I datasheet, SMB10J13AHM3_A/I pinout, SMB10J13AHM3_A/I application, or SMB10J13AHM3_A/I equivalent, key selection criteria include clamping performance under 100 A IFSM surge, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior follows IEEE C62.35 standards, with VC defined at IPPM derived from 10/1000 µs waveform testing under derated conditions above TA = 25 °C.
The SMB10J13AHM3_A/I is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA; defines safe operating margin for 12 V nominal systems. |
| VBR min/max | 14.4 V / 15.9 V at IT = 1.0 mA - guaranteed avalanche onset range; ensures predictable turn-on during transients. |
| VC @ IPPM | 21.5 V at 46.5 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to <22 V. |
| PPPM | 1000 W - peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity. |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine); withstands load-dump events in automotive 12 V systems. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| RθJA | 72 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" pads; informs heatsinking requirements for sustained surge duty. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Matte tin-plated leads, RoHS-compliant and halogen-free (HM3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to protected line (e.g., 12 V rail); conducts during positive surges when cathode is at higher potential. |
| Cathode | Avalanche clamping terminal | Marked with color band; tied to ground or lower-potential reference; sinks surge current into return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
| Glass passivated junction | Ensures stable VBR over lifetime and improved moisture resistance versus epoxy-passivated alternatives. |
| MSL Level 1 | Supports lead-free reflow up to 260 °C peak without popcorn effect or delamination. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving clamping fidelity. |
| Automated placement compatible | Standard SMB footprint and lead geometry enable high-yield pick-and-place on production SMT lines. |
Applications
| Automotive Sensor Interface Protection | Industrial 24 V Power Input |

IC Role / Device Role / Timing Role: Fast-clamping device across output terminals to absorb flyback spikes from transformer leakage inactivation. Use Value: Sub-ns response and 21.5 V VC ensure regulated output stays within ±5 % tolerance during 10/1000 µs surges, preserving USB compliance. |
Use Scenario: Distributed surge protection on 48 V backplane feeds powering remote radio units (RRUs) and baseband processing cards. IC Role / Device Role / Timing Role: Point-of-load TVS on each board's power entry connector to localize surge energy and prevent system-wide failure. Use Value: Halogen-free HM3 construction meets telecom flame-retardancy requirements (UL 94 V-0), while 150 °C TJ rating supports operation in sealed outdoor enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), VBR (14.4–15.9 V), and VC (21.5 V), 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 SMBJ13A-E3/52 when cost sensitivity outweighs automotive reliability requirements and halogen-free material is not required. |
| SAC13 | Lower PPPM (600 W), same VWM (13 V), higher VC (23.0 V at 26 A), SOD-123FL package (smaller footprint, higher RθJA). | Reduced surge handling and less effective clamping; limited to low-energy transients in space-constrained consumer devices. | Choose SAC13 only for compact, low-power applications where PCB area is critical and surge threat level is below IEC 61000-4-5 Level 2. |
Compared with SMBJ13A-E3/52, SMB10J13AHM3_A/I adds AEC-Q101 qualification and halogen-free construction for automotive use; compared with SAC13, it delivers 67 % higher peak power rating and tighter clamping, making it suitable for demanding industrial and automotive power rail protection.

FAQ
What is the clamping voltage of SMB10J13AHM3_A/I and how is it measured?
The SMB10J13AHM3_A/I has a maximum clamping voltage (VC) of 21.5 V, measured at a peak pulse current (IPPM) of 46.5 A using a standardized 10/1000 µs double-exponential waveform per ANSI/IEEE C62.35. This value reflects the actual voltage seen by downstream circuitry during surge events and is validated at TA = 25 °C on 5.0 mm × 5.0 mm copper pads. The SMB10J13AHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is SMB10J13AHM3_A/I qualified for automotive applications?
Yes, SMB10J13AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HM3" (halogen-free, RoHS-compliant, AEC-Q101 qualified). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and mechanical shock to meet automotive reliability requirements. The SMB10J13AHM3_A/I is intended for use in engine control units, body electronics, and ADAS sensor modules where automotive-grade certification is mandatory.
What does the "HM3" suffix mean in SMB10J13AHM3_A/I?
The "HM3" suffix in SMB10J13AHM3_A/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes the part from commercial variants (e.g., "E3" or "M3") and confirms compliance with automotive material standards and environmental regulations. The "_A/I" denotes packaging: "A" is the revision code, and "I" specifies 13″ diameter tape-and-reel delivery (3200 units per reel). This full designation ensures traceability and correct material attribution for SMB10J13AHM3_A/I.
How does SMB10J13AHM3_A/I compare to bidirectional TVS diodes with the same VWM?
SMB10J13AHM3_A/I is unidirectional and optimized for DC rail protection where polarity is fixed, offering higher peak pulse power (1000 W vs. 800 W for bidirectional SMB8J13CA) and lower clamping voltage at equivalent current. Bidirectional variants like SMB8J13CA are used in AC-coupled or polarity-agnostic signal lines (e.g., RS-485), but their symmetric structure reduces surge capacity. For 12 V automotive power rails, SMB10J13AHM3_A/I provides superior energy handling and tighter clamping than any bidirectional counterpart in the SMB family.
What is the thermal resistance of SMB10J13AHM3_A/I and how does it affect layout?
The SMB10J13AHM3_A/I 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. This value assumes standard FR-4 PCB with no internal copper planes. To maintain safe junction temperatures during repeated surges, designers must provide adequate copper area and consider thermal vias beneath the cathode/anode pads. Layout deviations from the recommended pad size directly increase RθJA, potentially causing premature thermal failure of SMB10J13AHM3_A/I under sustained stress.
