Product details
Overview
SMB10J16AHM3_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 power and signal lines. It features 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), 1000 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use - deployed to protect MOSFETs, sensor interfaces, and microcontroller I/O in engine control units.
For engineers reviewing the SMB10J16AHM3_A/I datasheet, SMB10J16AHM3_A/I pinout, SMB10J16AHM3_A/I application, or SMB10J16AHM3_A/I equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity with cathode band marking, AEC-Q101 compliance status, thermal resistance (RθJA = 72 °C/W), and halogen-free RoHS-compliant construction (HM3 suffix).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, leveraging an avalanche breakdown mechanism to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the SMB package supports automated SMT placement and meets MSL Level 1 (260 °C reflow peak).
Designed for single-polarity DC line protection, SMB10J16AHM3_A/I responds within picoseconds to ESD and lightning-induced surges per IEC 61000-4-2/4-5, with clamping action defined by its 17.8–19.7 V breakdown range (VBR at 1.0 mA) and 26.0 V VC limit at rated IPPM. It is not intended for bidirectional AC line protection or continuous overvoltage regulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHE3_A/H | Same VWM/VC/PPPM, but E3 suffix (non-halogen-free, commercial grade); RθJA identical; no AEC-Q101 validation. | Approved for industrial/commercial automotive infotainment, not powertrain or safety-critical systems. | Select when halogen-free requirement or AEC-Q101 certification is not mandated; lower cost, same footprint. |
| 1.5SMC16A | Same electrical specs but in larger SMC (DO-214AB) package; 1.5 kW PPPM; higher RθJA (50 °C/W); lead-free only (no HM3 variant). | Better thermal handling for high-duty-cycle surges; requires larger PCB area and different pad layout. | Choose for higher surge endurance where board space permits and halogen-free is optional. |
Compared with SMBJ16AHE3_A/H and 1.5SMC16A, SMB10J16AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it the only option qualified for under-hood automotive applications requiring both environmental compliance and functional safety alignment.

FAQ
What is the clamping voltage of SMB10J16AHM3_A/I at its rated peak pulse current?
The SMB10J16AHM3_A/I has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPPM) of 38.5 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events. The SMB10J16AHM3_A/I datasheet specifies this parameter in Table 1 (Unidirectional Devices) on page 2, confirming its suitability for protecting 16 V nominal systems where downstream ICs tolerate up to 26 V transient stress.
Is SMB10J16AHM3_A/I suitable for bidirectional signal line protection?
No, SMB10J16AHM3_A/I is a unidirectional TVS diode, intended only for DC or single-polarity line protection. Its cathode band marking and asymmetric IV curve mean it conducts only when cathode voltage exceeds anode by ≥VBR. For bidirectional protection (e.g., AC lines or differential buses), Vishay offers the SMB8J16CA variant - which shares the same VWM and VC but supports symmetrical clamping. Using SMB10J16AHM3_A/I on bidirectional signals risks forward conduction during negative half-cycles and invalidates its protection function.
Does SMB10J16AHM3_A/I meet AEC-Q101 requirements for automotive use?
Yes, SMB10J16AHM3_A/I is explicitly AEC-Q101 qualified, as confirmed in the Vishay document 88422 (Revision 09-Jan-2024), Section "FEATURES" and "ORDERING INFORMATION". The "HM3" suffix denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. This qualification covers stress tests including HTGB, H3TRB, TC, and UHAST - validating its use in engine control, body electronics, and ADAS modules where automotive-grade reliability is mandatory. The SMB10J16AHM3_A/I part number appears in the qualified AEC-Q101 ordering table with suffix "_B/I" indicating 13" tape-and-reel packaging.
What is the thermal resistance of SMB10J16AHM3_A/I, and how does it affect PCB layout?
SMB10J16AHM3_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, as specified in the Thermal Characteristics table (page 3). This value assumes minimum recommended pad layout; reducing pad area increases RθJA, risking thermal runaway during repetitive surges. To maintain reliability, designers must allocate at least 5.0 mm × 5.0 mm Cu per terminal and avoid thermal isolation - the SMB10J16AHM3_A/I performance degrades rapidly if RθJA exceeds 85 °C/W.
How does the HM3 suffix in SMB10J16AHM3_A/I differ from E3 or M3 variants?
"HM3" indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, whereas "E3" is RoHS-compliant commercial grade (no AEC-Q101), and "M3" is halogen-free RoHS-compliant commercial grade (also no AEC-Q101). The HM3 variant uses bromine-free flame retardants in the molding compound and passes JESD201 Class 2 whisker testing - critical for automotive under-hood deployment. All three share identical electrical specs and SMB package, but only HM3 carries the full automotive qualification required for powertrain and safety-related systems using SMB10J16AHM3_A/I.
