Product details
Overview
SMBG16A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1.0 mA test current, and 600 W peak pulse power (10/1000 µs). It clamps transients to ≤26.0 V at 23.1 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SMBG16A-E3/52 datasheet, SMBG16A-E3/52 pinout, SMBG16A-E3/52 application, or SMBG16A-E3/52 equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at 16 V, 150 °C max junction temperature, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, responding to fast-rising voltage transients (e.g., ESD, load dump, inductive switching) by avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance for consistent clamping performance under repetitive surges.
The SMBG16A-E3/52 is designed for unidirectional protection only - cathode marked with band - and exhibits 100 °C/W typical junction-to-ambient thermal resistance when mounted per recommended pad layout. It meets J-STD-020 MSL Level 1 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - defines reliable avalanche initiation range for design margining |
| VC @ IPPM | 26.0 V at 23.1 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| IPPM | 23.1 A - peak surge current capability with 10/1000 µs waveform, derated above 25 °C |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |

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 (16 V), but lower PPPM (600 W vs. SMBJ's 600 W), identical SMB package; slightly higher VC (27.7 V vs. 26.0 V) | Less stringent clamping; suitable where 1.7 V higher clamping voltage is acceptable | Select SMBG16A-E3/52 when tighter clamping (26.0 V) and AEC-Q101 qualification are required. |
| 1.5SMC16A | Same VWM/VBR specs, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher thermal mass but incompatible footprint | Requires PCB redesign; preferred for higher-power or legacy designs with SMC land patterns | Choose SMBG16A-E3/52 for new SMT designs prioritizing space savings and automotive qualification. |
Compared with SMBJ16A-E3/52 and 1.5SMC16A, the SMBG16A-E3/52 delivers superior clamping (26.0 V), AEC-Q101 validation, and SMBG's optimized thermal resistance (RθJA = 100 °C/W), making it the preferred choice for next-generation automotive and space-constrained industrial modules.

FAQ
What is the clamping voltage of SMBG16A-E3/52 and how is it measured?
The SMBG16A-E3/52 has a maximum clamping voltage (VC) of 26.0 V, measured at its peak pulse current (IPPM) of 23.1 A using a standardized 10/1000 µs double-exponential transient waveform. This value is guaranteed across temperature and production lots per Vishay's 88456 specification document, ensuring predictable overvoltage protection for downstream components.
Is SMBG16A-E3/52 suitable for automotive applications?
Yes, SMBG16A-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - glass-passivated junction, MSL Level 1 rating, and operation up to +150 °C - meets requirements for engine control, body electronics, and ADAS subsystems. The "HE3" variant designation confirms full AEC-Q101 compliance, and SMBG16A-E3/52 belongs to that qualified family.
What does the "-E3/52" suffix mean in SMBG16A-E3/52?
The "E3" suffix indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7″ diameter plastic tape and reel, with 750 units per reel. This format is optimized for high-speed SMT placement and conforms to J-STD-002 solderability standards, ensuring reliable assembly yield in automated production lines.
How does SMBG16A-E3/52 differ from bidirectional TVS diodes like SMBG16CA?
SMBG16A-E3/52 is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMBG16CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The unidirectional SMBG16A-E3/52 offers lower leakage (<1.0 µA) and tighter VBR tolerance, making it ideal for DC power rail protection where reverse conduction must be blocked.
Can SMBG16A-E3/52 replace SMBJ16A in an existing design?
SMBG16A-E3/52 is not a direct drop-in replacement for SMBJ16A due to differences in package outline (SMBG vs. SMB) and thermal pad layout requirements. While both share the same VWM and nominal power rating, SMBG16A-E3/52 requires verification of solder mask clearance and copper pad dimensions per its DO-215AA mechanical drawing to ensure thermal performance and mechanical reliability.
