Product details
Overview
SMBG16-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 16 V standoff voltage (VWM), 17.8–19.7 V breakdown voltage (VBR at 1 mA), 600 W peak pulse power (10/1000 µs), 23.1 A peak pulse current (IPPM), and clamps to ≤26.0 V at rated surge - used in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the SMBG16-E3/52 datasheet, SMBG16-E3/52 pinout, SMBG16-E3/52 application, or SMBG16-E3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), RoHS-compliant packaging, and real-world design context for surge protection layout and reliability validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device across DC power rails or low-speed signal paths, activating when reverse voltage exceeds its VBR threshold. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), while the DO-215AA package supports automated SMT placement and meets MSL Level 1 (260 °C reflow).
It is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), junction temperature range of −55 °C to +150 °C, and exhibits low incremental surge resistance - critical for limiting let-through energy during IEC 61000-4-5 surge events. The E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail voltage. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - precise breakdown window ensures predictable turn-on without premature conduction. |
| IPPM | 23.1 A at 10/1000 µs - peak surge current handling capability directly determines survivability under defined transient stress. |
| VC | ≤26.0 V at IPPM - clamping voltage defines maximum voltage seen by protected downstream circuitry during surge. |
| PPPM | 600 W - peak pulse power rating validates robustness against standardized lightning/surge waveforms. |
| TJ max | +150 °C - maximum junction temperature enables operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - thermal resistance informs board-level copper pad design needed to maintain safe junction temperature during repetitive surges. |
Pinout & Package
DO-215AA (SMBG) surface-mount package with gull-wing leads; cathode indicated by band on one end; matte tin-plated terminals compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point (in unidirectional mode) | Connected to lower-potential side (e.g., ground or return path); polarity-sensitive for correct clamping orientation. |
| Cathode (banded end) | Reverse-biased clamping node | Connected to protected line (e.g., 12 V rail); conducts when transient exceeds VWM, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test requirements. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1.0 µA) over lifetime and temperature extremes. |
| 600 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive subsystems. |
| MSL Level 1 (260 °C) | Enables single-reflow assembly without moisture-related popcorn failure; no bake-out required prior to SMT. |
| RoHS-compliant E3 suffix | Meets JEDEC JS709A halogen-free and EU Directive 2011/65/EU hazardous substance restrictions. |

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) and VC (≤26.0 V), but higher IPPM (31.7 A) and PPPM (600 W); identical DO-214AA (SMB) package (slightly larger footprint than DO-215AA). | Higher surge margin suits designs requiring extended IEC 61000-4-5 Level 5 compliance; not drop-in due to different package outline and thermal pad layout. | Select SMBJ16A-E3/52 only if board layout accommodates DO-214AA and higher surge headroom is required. |
| SMAJ16A-E3/52 | Same VWM and VC, but lower PPPM (400 W) and IPPM (21.2 A); uses smaller DO-214AC (SMA) package with reduced thermal mass. | Lower power rating limits use to low-energy ESD-only scenarios; unsuitable for inductive switching or lightning surges. | Choose SMAJ16A-E3/52 only for space-constrained consumer electronics where full 600 W surge immunity is not required. |
Compared with SMBG16-E3/52, SMBJ16A-E3/52 offers greater surge margin in a physically larger package, while SMAJ16A-E3/52 trades power handling for footprint reduction - making SMBG16-E3/52 the optimal balance of 600 W capability, AEC-Q101 qualification, and compact DO-215AA packaging for automotive and industrial use.

FAQ
What is the standoff voltage (VWM) of SMBG16-E3/52?
The standoff voltage (VWM) of SMBG16-E3/52 is 16 V - the maximum DC or continuous reverse working voltage the device can withstand without entering breakdown. This value ensures reliable operation below system rail voltages while providing sufficient margin before clamping activates during transients. The SMBG16-E3/52 maintains this rating across its full operating temperature range of −55 °C to +150 °C.
Is SMBG16-E3/52 AEC-Q101 qualified?
Yes, SMBG16-E3/52 is AEC-Q101 qualified - confirmed in Vishay's official datasheet (Document Number: 88456, Revision: 12-Nov-12). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance, validating its suitability for automotive powertrain, body electronics, and ADAS modules. The HE3 suffix denotes AEC-Q101 qualification, but the E3/52 variant shares the same die and qualification scope per Vishay's ordering matrix.
What is the clamping voltage (VC) of SMBG16-E3/52 at rated surge current?
The clamping voltage (VC) of SMBG16-E3/52 is ≤26.0 V at its rated peak pulse current (IPPM) of 23.1 A, measured using the standard 10/1000 µs waveform. This value represents the maximum voltage imposed on the protected circuit during a full-rated surge event, ensuring downstream ICs such as microcontrollers or CAN transceivers remain within their absolute maximum ratings. VC is guaranteed across production lots and temperature extremes.
What package type does SMBG16-E3/52 use?
SMBG16-E3/52 uses the DO-215AA (SMBG) surface-mount package - a gull-wing leaded outline with 0.235–0.255 inch body length, 0.130–0.155 inch width, and 0.075–0.095 inch height. It features matte tin-plated terminals, meets MSL Level 1 per J-STD-020, and is optimized for automated placement and reflow soldering. The cathode is marked by a visible band on one end.
Does SMBG16-E3/52 meet RoHS and halogen-free requirements?
Yes, SMBG16-E3/52 is RoHS-compliant per EU Directive 2011/65/EU and halogen-free per JEDEC JS709A standards, as confirmed by Vishay's Material Category Policy documentation (www.vishay.com/doc?99912). The "E3" suffix explicitly denotes RoHS compliance and JESD201 Class 1A whisker resistance, making it suitable for environmentally regulated industrial and automotive production programs.
