Product details
Overview
SMBG16-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for primary-level overvoltage protection of DC power rails and signal lines. It features 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 - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the SMBG16-E3/5B datasheet, SMBG16-E3/5B pinout, SMBG16-E3/5B application, or SMBG16-E3/5B 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 device operates as a silicon avalanche diode, clamping transients by entering avalanche breakdown when reverse voltage exceeds VBR. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Thermal performance is defined by RθJA = 100 °C/W (on recommended pad layout) and maximum junction temperature of +150 °C. The 100 A IFSM (8.3 ms half-sine) rating supports robust surge handling in automotive load-dump scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected circuit's normal DC rail. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - Confirmed breakdown range ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | 26.0 V at 23.1 A - Clamped voltage during 10/1000 µs surge; defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 600 W - Peak pulse power dissipation capability; determines survivability against standardized surge waveforms. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); validates suitability for automotive load-dump protection. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
Pinout & Package
Package: DO-215AA (SMBG), surface-mount gull-wing leaded case per JEDEC MO-215. Dimensions: 4.57 mm × 3.94 mm × 2.10 mm (L × W × H). Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements. Cathode indicated by band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; carries surge current during clamping. |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanche breakdown initiates here when VWM is exceeded. |
Key Features

|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| Glass passivated junction | Enhances long-term stability and reduces parameter drift under thermal stress and high-humidity operating conditions. |
| 600 W 10/1000 µs rating | Meets ISO 7637-2 Pulse 1, 2a, 3a/b and IEC 61000-4-5 Level 3 surge immunity requirements for industrial and automotive systems. |

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), identical DO-214AB (SMB) package but larger footprint (4.57 mm × 3.94 mm vs. DO-215AA's 4.57 mm × 3.94 mm - same outline but different leadform); RθJA = 85 °C/W vs. 100 °C/W. | Higher thermal efficiency allows higher sustained surge repetition rates; preferred where board space permits larger pad layout. | Select SMBJ16A-E3/52 if thermal derating margin is critical and PCB layout accommodates SMB footprint. |
| 1.5SMC16A | Same electrical specs (VWM = 16 V, VC = 26.0 V), but DO-214AB (SMC) package - 7.11 mm × 6.22 mm, ~2.5× larger area; rated for 1.5 kW PPPM. | Higher power handling supports multi-pulse surge environments (e.g., railway signaling), but incompatible with dense automotive PCBs. | Choose 1.5SMC16A only when system-level surge testing requires >600 W single-pulse rating and board space is unconstrained. |
Compared with SMBJ16A-E3/52 and 1.5SMC16A, SMBG16-E3/5B delivers identical clamping performance in the smallest qualified surface-mount TVS package (DO-215AA), making it optimal for space-constrained AEC-Q101-compliant designs where thermal load is managed via copper pour and airflow.

FAQ
What is the polarity configuration of SMBG16-E3/5B?
SMBG16-E3/5B is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the package body, and it conducts in forward direction (anode to cathode) while clamping reverse transients above its breakdown voltage. This configuration is intended for DC rail protection where polarity is fixed, unlike bi-directional variants that use "CA" suffixes.
Does SMBG16-E3/5B meet automotive qualification standards?
Yes, SMBG16-E3/5B is AEC-Q101 qualified - confirmed in Vishay's official documentation (Document Number 88456, Revision 12-Nov-12). This certification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness, validating its use in engine control modules, body electronics, and ADAS subsystems.
What is the maximum clamping voltage for SMBG16-E3/5B under surge conditions?
The maximum clamping voltage (VC) for SMBG16-E3/5B is 26.0 V, measured at 23.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is guaranteed across the full operating temperature range.
Can SMBG16-E3/5B be used in lead-free reflow processes?
Yes, SMBG16-E3/5B is rated MSL Level 1 with a maximum peak reflow temperature of 260 °C, fully compatible with standard lead-free soldering profiles (e.g., IPC/JEDEC J-STD-020). No pre-baking is required, and its matte tin-plated leads ensure reliable wetting per J-STD-002 and JESD 22-B102.
How does the DO-215AA (SMBG) package compare to DO-214AB (SMB) in size and thermal performance?
The DO-215AA (SMBG) package used by SMBG16-E3/5B has identical length and width (4.57 mm × 3.94 mm) to DO-214AB (SMB) but features modified gull-wing leads for improved coplanarity and automated placement yield. Its thermal resistance is RθJA = 100 °C/W (vs. ~85 °C/W for SMB), reflecting slightly reduced heat dissipation due to smaller thermal pad area - compensated by optimized PCB copper layout.
