Product details
Overview
SMBG16HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of power 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 23.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power electronics and industrial sensor interfaces.
For engineers reviewing the SMBG16HE3/52 datasheet, SMBG16HE3/52 pinout, SMBG16HE3/52 application, or SMBG16HE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), RoHS-compliant HE3 suffix marking, and DO-215AA mechanical dimensions critical for PCB layout and reliability validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 16 V), then rapidly avalanches to clamp transients above ~17.8 V. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 µs surges at 0.01% duty cycle.
Designed for surface-mount automated placement, SMBG16HE3/52 uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker testing. Its MSL Level 1 rating (peak reflow 260 °C) and -55 °C to +150 °C operating junction temperature support automotive under-hood and industrial control applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM (16 V), but lower PPPM = 600 W (identical), higher VC = 27.7 V at 21.7 A; non-AEC-Q101, commercial grade only. | Lacks automotive qualification; suitable for consumer/industrial designs where AEC-Q101 is not mandated. | Select SMBJ16A-E3/52 if cost sensitivity outweighs automotive qualification and slightly higher clamping is acceptable. |
| SMCJ16A-E3/52 | Same VWM (16 V), but larger DO-214AB (SMC) package; higher PPPM = 1500 W; VC = 25.8 V at 58.1 A. | Requires larger PCB area; used where higher surge energy (e.g., IEC 61000-4-5 Level 5) must be absorbed. | Choose SMCJ16A-E3/52 only when 600 W is insufficient and board space permits DO-214AB footprint. |
Compared with SMBJ16A-E3/52, SMBG16HE3/52 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; versus SMCJ16A-E3/52, it trades surge capacity for 40% smaller footprint and tighter VC consistency at lower currents.

FAQ
What is the clamping voltage of SMBG16HE3/52 and how is it measured?
The SMBG16HE3/52 has a maximum clamping voltage (VC) of 26.0 V, measured at its rated peak pulse current (IPPM) of 23.1 A using a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88456, Rev. 12-Nov-12) and reflects the voltage across SMBG16HE3/52 during worst-case transient conduction - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBG16HE3/52 suitable for automotive applications?
Yes, SMBG16HE3/52 is AEC-Q101 qualified, explicitly certified for automotive use per Vishay's documentation. Its construction - including glass-passivated junction, MSL Level 1 reflow compatibility, and JESD 201 Class 2 whisker resistance - meets stringent requirements for engine control, body electronics, and ADAS subsystems where reliability under thermal and mechanical stress is mandatory.
What does the "HE3" suffix indicate in SMBG16HE3/52?
The "HE3" suffix in SMBG16HE3/52 denotes two key attributes: "H" signifies AEC-Q101 qualification, and "E3" indicates RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade "E3" variants (e.g., SMBG16A-E3/52) and confirms suitability for automotive and high-reliability industrial deployments.
How does SMBG16HE3/52 differ from SMBJ16A-E3/52?
SMBG16HE3/52 and SMBJ16A-E3/52 share identical VWM (16 V) and PPPM (600 W), but SMBG16HE3/52 is AEC-Q101 qualified and uses the smaller DO-215AA (SMBG) package, while SMBJ16A-E3/52 is commercial-grade in DO-214AA (SMB) package with slightly higher VC (27.7 V). The HE3 suffix also guarantees JESD 201 Class 2 whisker resistance.
What is the thermal resistance of SMBG16HE3/52 and why does it matter?
SMBG16HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value determines how much the junction temperature rises under power dissipation - essential for derating peak pulse capability above 25 °C ambient and ensuring long-term reliability in enclosed or high-temperature environments.
