Product details
Overview
SMB10J16AHE3/5B 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 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, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the SMB10J16AHE3/5B datasheet, SMB10J16AHE3/5B pinout, SMB10J16AHE3/5B application, or SMB10J16AHE3/5B 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 transitions from high-impedance to low-impedance state during voltage transients exceeding its breakdown threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Thermal design relies on RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), with maximum junction temperature rated at +150 °C. The device is qualified per AEC-Q101 and meets MSL Level 1 (260 °C reflow peak), supporting automotive-grade reliability without derating under standard PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected line. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on across production lot and temperature. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamping voltage under 10/1000 µs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 1000 W - Peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports inrush and fault-current tolerance. |
| Junction Temp Range | −55 °C to +150 °C - Enables operation in under-hood automotive and industrial environments without thermal shutdown. |
| Leakage Current | ≤1.0 µA at VWM - Minimal standby power loss and negligible loading on low-power sensor or logic circuits. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V supply inputs of engine control units (ECUs) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery feed and LDO input, absorbing >100 V transients within nanoseconds.

Use Value: Maintains signal integrity and avoids false triggering of ADCs or op-amps while meeting IEC 61000-4-5 Level 3 immunity requirements. |
| Consumer Power Adapter Input | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding primary-side rectifier outputs in universal-input AC/DC adapters against line surges and EFT bursts. IC Role / Device Role / Timing Role: Fast-response TVS placed across bulk capacitor, clamping transients before they reach PWM controller or MOSFET gate drivers. Use Value: Eliminates need for oversized capacitors or redundant fusing while achieving UL 1449 Type 4 compliance. | Use Scenario: Front-end protection of Ethernet PHY or xDSL line drivers exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Unidirectional TVS integrated into hybrid coupler circuitry, shunting surge energy to chassis ground before reaching transformer isolation barrier. Use Value: Preserves signal-to-noise ratio and prevents saturation of magnetics during 6 kV ring-wave tests per GR-1089-CORE. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM/VC, but commercial-grade (non-AEC-Q101), RoHS-compliant only. | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules. | Select when cost sensitivity outweighs automotive reliability requirements and no AEC-Q101 documentation is mandated. |
| 1.5SMC16A | Same electrical specs but larger SMC (DO-214AB) package (0.280" × 0.240"); higher RθJA (50 °C/W). | Requires larger PCB area and different pad layout; less suitable for high-density automotive modules. | Choose only if existing board uses SMC footprint and thermal budget allows higher junction rise. |
Compared with SMBJ16A-E3/52 and 1.5SMC16A, SMB10J16AHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and 1000 W surge capability - making it the preferred choice for next-generation automotive and industrial designs requiring validated reliability in compact layouts.

FAQ
What is the clamping voltage of SMB10J16AHE3/5B at its rated peak pulse current?
The SMB10J16AHE3/5B has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 38.5 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees consistent overvoltage limiting behavior across production lots and temperature ranges from −55 °C to +150 °C.
Is SMB10J16AHE3/5B suitable for automotive applications?
Yes, SMB10J16AHE3/5B is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliance and automotive-grade reliability. It is explicitly rated for under-hood and chassis-mounted applications where junction temperatures reach +150 °C and surge immunity must meet ISO 7637-2 and ISO 16750-2 requirements - confirmed in Vishay Document Number 88422, Revision 09-Jan-2024.
What does the "5B" in SMB10J16AHE3/5B indicate?
The "5B" in SMB10J16AHE3/5B denotes the packaging configuration: 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This format supports high-volume SMT assembly and is distinct from "52" (7-inch reel, 750 units) and "H/I" variants used for different reel sizes and moisture sensitivity levels.
How does SMB10J16AHE3/5B differ from bidirectional TVS diodes like SMB8J16CA?
SMB10J16AHE3/5B is unidirectional and optimized for DC power rail protection with asymmetric conduction - conducting only in forward direction while clamping reverse transients. In contrast, SMB8J16CA is bidirectional, offering symmetrical clamping for AC or floating signal lines. Their peak pulse power ratings also differ: 1000 W (unidirectional) vs. 800 W (bidirectional), reflecting internal construction differences.
What is the thermal resistance from junction to ambient for SMB10J16AHE3/5B?
The typical thermal resistance from junction to ambient (RθJA) for SMB10J16AHE3/5B is 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay Document Number 88422. This value assumes standard JEDEC test conditions and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures.
