Product details
Overview
SMB10J16A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 16 V stand-off voltage (VWM), and 26.0 V clamping voltage (VC) at 38.5 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain control modules.
For engineers reviewing the SMB10J16A-E3/5B datasheet, SMB10J16A-E3/5B pinout, SMB10J16A-E3/5B application, or SMB10J16A-E3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 17.8–19.7 V breakdown range, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin plating.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD and inductive switching transients per IEC 61000-4-2/4-4/4-5. Its unidirectional configuration provides asymmetric clamping-low forward voltage drop (VF = 3.5 V at 50 A) on anode-to-cathode conduction while blocking reverse current until VBR is exceeded.
The device operates across -55 °C to +150 °C junction temperature, with MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility. Thermal performance is optimized via low RθJL (20 °C/W), allowing efficient heat transfer to PCB copper pads (0.2" × 0.2") without heatsinking in typical 1000 W surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage trip threshold. |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM under production tolerance. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamping voltage during 1000 W surge defines maximum stress imposed on protected downstream circuitry. |
| PPPM | 1000 W (10/1000 µs) - Peak surge power rating validated per ANSI/IEEE C62.35, suitable for ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| IFSM | 100 A (8.3 ms half-sine) - Surge current handling capability supports repeated load-dump events in 12 V vehicle electrical systems. |
| TJ max | +150 °C - Enables operation in under-hood environments without derating in most PCB layouts with recommended pad area. |

FAQ
What is the clamping voltage of SMB10J16A-E3/5B at its rated peak pulse current?
The SMB10J16A-E3/5B has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPPM) of 38.5 A, measured under the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 1000 W transient event and is confirmed in the Vishay Document Number 88422, page 2, unidirectional electrical characteristics table.
Is SMB10J16A-E3/5B qualified for automotive applications?
Yes, SMB10J16A-E3/5B is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number 88422, page 1, FEATURES section). The "HE3" or "HM3" suffix denotes AEC-Q101 qualification; however, the E3/5B variant is RoHS-compliant commercial grade. For automotive use, the HE3 or HM3 version (e.g., SMB10J16AHE3_B/I) must be selected-SMB10J16A-E3/5B itself is not AEC-Q101 qualified.
What is the breakdown voltage range for SMB10J16A-E3/5B?
The breakdown voltage (VBR) for SMB10J16A-E3/5B is specified as 17.8 V minimum and 19.7 V maximum at a test current (IT) of 1.0 mA, per the unidirectional electrical characteristics table on page 2 of Vishay Document Number 88422. This 1.9 V spread reflects production tolerance and ensures consistent turn-on behavior across temperature and lifetime.
Does SMB10J16A-E3/5B have polarity marking, and how is it identified?
Yes, SMB10J16A-E3/5B is unidirectional and features a visible cathode band on the SMB (DO-214AA) package body. As documented on page 5 of Vishay Document Number 88422, the color band denotes the cathode terminal, which must be connected toward the side of the circuit requiring overvoltage protection (e.g., VCC or signal line), while the anode connects to ground or return path.
What is the maximum junction temperature and thermal resistance of SMB10J16A-E3/5B?
The SMB10J16A-E3/5B has a maximum junction temperature (TJ) of +150 °C and a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, per the Thermal Characteristics table on page 4 of Vishay Document Number 88422. These values enable reliable operation in under-hood automotive environments when mounted on the recommended 0.2" × 0.2" copper pads.
