Product details
Overview
SMB10J16-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 16 V standoff 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 power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J16-E3/52 datasheet, SMB10J16-E3/52 pinout, SMB10J16-E3/52 application, or SMB10J16-E3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, RoHS-compliant matte tin plating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 16 V), but triggers into low-impedance conduction when transient voltage exceeds its 17.8 V minimum breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion without thermal runaway.
The device is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets J-STD-020 MSL Level 1 and passes JESD201 Class 1A whisker testing - confirming suitability for reflow-soldered automotive and industrial PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - precise breakdown range ensures predictable turn-on timing across production lots |
| VC @ IPPM | 26.0 V at 38.5 A - clamping voltage during 10/1000 µs surge; limits protected circuit stress to safe levels |
| PPPM | 1000 W - peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity |
| IFSM | 100 A - non-repetitive forward surge current rating; validates robustness against inductive switch-off transients |
| TJ max | 150 °C - maximum junction temperature; enables operation in under-hood automotive environments |

| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients; improves protection margin for downstream ICs |
| RoHS-compliant & halogen-free | Fulfills JEDEC JS709A and EU Directive 2011/65/EU requirements; supports green manufacturing compliance |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 16750-2) and jump-start surges. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between VBAT and GND, clamping spikes within nanoseconds. Use Value: Limits voltage seen by downstream PMICs and microcontrollers to ≤26.0 V, preventing latch-up or gate oxide damage. | Use Scenario: 4–20 mA current loop sensors in factory automation subject to EFT/burst noise (IEC 61000-4-4). IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS placed across signal and return lines to absorb coupled transients. Use Value: Maintains signal integrity by suppressing >1 kV transients while adding <1 pF capacitance - no data corruption or false triggering. |
| DC-DC Converter Input Stage | USB Port Overvoltage Clamp |
Use Scenario: 24 V input to buck converter in railway control systems experiencing switching-induced transients. IC Role / Device Role / Timing Role: Primary front-end clamp protecting MOSFET gate drivers and controller ICs from reflected surge energy. Use Value: Withstands 100 A surge (8.3 ms half-sine) and dissipates 1000 W peak power without degradation - extends system uptime. | Use Scenario: USB 2.0 VBUS line in portable medical devices requiring ESD immunity per IEC 61000-4-2 Level 4 (±15 kV air). IC Role / Device Role / Timing Role: Unidirectional TVS tied between VBUS and GND to shunt ESD events before reaching USB transceiver. Use Value: Clamps ±15 kV contact discharge to <26 V in <1 ns, preserving USB enumeration and preventing PHY latch-up. |
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 DO-214AA package, identical VWM/VBR/VC specs, but not AEC-Q101 qualified | Limited to commercial/industrial use; unsuitable for automotive OEM designs requiring qualification evidence | Select SMB10J16-E3/52 when AEC-Q101 documentation and traceability are mandatory |
| SMCJ16AHE3/52 | DO-214AB (SMC) package - larger footprint, higher PPPM (1500 W), same electrical specs | Requires PCB layout change; preferred where higher surge margin or thermal mass is needed | Choose SMB10J16-E3/52 for space-constrained layouts where 1000 W suffices and DO-214AA is standard |
Compared with SMBJ16A-E3/52 and SMCJ16AHE3/52, SMB10J16-E3/52 uniquely combines AEC-Q101 qualification, DO-214AA footprint, and 1000 W surge rating - making it optimal for automotive Tier-1 modules and compact industrial controllers needing certified reliability without board redesign.

FAQ
What is the polarity configuration of SMB10J16-E3/52?
SMB10J16-E3/52 is a unidirectional TVS diode, with the cathode identified by a color band on the package body. It conducts only when the cathode is at a higher potential than the anode - making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like SMB8J16CA, which protect AC or dual-polarity signals.
Does SMB10J16-E3/52 meet automotive qualification standards?
Yes, SMB10J16-E3/52 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard. The "HE3" suffix denotes AEC-Q101 qualification; however, SMB10J16-E3/52 uses the commercial "E3" suffix but is explicitly listed in the AEC-Q101-qualified family per Vishay document 88422, Revision 12-Nov-12.
What is the maximum clamping voltage of SMB10J16-E3/52 under surge conditions?
The maximum clamping voltage (VC) of SMB10J16-E3/52 is 26.0 V at 38.5 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on the protected circuit during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can SMB10J16-E3/52 be used in automated SMT assembly processes?
Yes, SMB10J16-E3/52 is optimized for automated placement: it uses a low-profile DO-214AA (SMB) package, meets MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C), and features matte tin-plated leads compliant with J-STD-002. The 7" tape-and-reel packaging (code /52) supports standard pick-and-place feeders without modification.
How does SMB10J16-E3/52 compare to SMBJ16A in terms of surge capability?
SMB10J16-E3/52 and SMBJ16A share identical electrical specifications (VWM, VBR, VC, PPPM) and DO-214AA packaging, but SMB10J16-E3/52 is explicitly AEC-Q101 qualified while SMBJ16A is commercial-grade. Both handle 1000 W surges, yet only SMB10J16-E3/52 provides documented automotive reliability evidence required for Tier-1 approvals.
