Product details
Overview
SMBG16CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 26.0 V at 23.1 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG16CA-E3/5B datasheet, SMBG16CA-E3/5B pinout, SMBG16CA-E3/5B application, or SMBG16CA-E3/5B equivalent, this device is selected for high-reliability surge suppression in automotive sensor interfaces, industrial I/O lines, telecom line cards, and DC power rail protection where bidirectional clamping, low clamping ratio, and MSL Level 1 solderability are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The SMBG16CA-E3/5B is rated for TJ = –55 °C to +150 °C, exhibits RθJA = 100 °C/W, and meets J-STD-020 MSL Level 1 with 260 °C peak reflow profile - confirming suitability for automated SMT assembly in harsh-environment applications without derating concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse/forward working voltage before clamping begins |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - Ensures reliable triggering above system operating voltage with margin |
| VC @ IPPM | 26.0 V at 23.1 A - Limits transient voltage seen by protected ICs to safe levels during 600 W surge |
| PPPM | 600 W (10/1000 µs) - Withstands industry-standard lightning/surge waveforms per IEC 61000-4-5 |
| ID @ VWM | ≤1.0 µA - Negligible leakage current preserves signal integrity and battery life in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-E3/52 | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating), different packaging (7″ reel, 750 pcs) | Identical electrical performance; differs only in reel size and quantity - suitable for low-volume prototyping or legacy BOMs | Select SMBJ16CA-E3/52 when smaller reels align with SMT line changeover frequency or inventory turnover targets. |
| SMCJ16CA-E3/5B | Same VWM/VBR, but higher PPPM = 1500 W and larger SMC (DO-214AB) package | Offers greater surge margin for high-energy threats (e.g., outdoor telecom, railway systems), but requires larger PCB footprint | Choose SMCJ16CA-E3/5B only if system-level testing confirms need for >600 W capability and board space permits larger package. |
Compared with SMBJ16CA-E3/52, SMBG16CA-E3/5B offers identical protection specs in a more compact SMBG footprint and higher-volume reel; versus SMCJ16CA-E3/5B, it trades surge headroom for space savings and cost efficiency in space-constrained automotive and industrial modules.

FAQ
What is the clamping voltage of SMBG16CA-E3/5B and how does it protect downstream components?
The SMBG16CA-E3/5B has a maximum clamping voltage (VC) of 26.0 V at 23.1 A peak pulse current. This means that during a 600 W transient event (10/1000 µs waveform), the device limits the voltage across protected circuitry to ≤26.0 V - well below typical IC absolute maximum ratings - thereby preventing overvoltage damage to microcontrollers, transceivers, or sensors connected to the same line.
Is SMBG16CA-E3/5B unidirectional or bidirectional, and how does that affect its use in circuit design?
SMBG16CA-E3/5B is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., SMBG16A), it requires no polarity marking during placement and is ideal for AC-coupled lines, floating references, or differential signal paths such as CAN, RS-485, or Ethernet, where voltage transients can occur with either polarity.
Does SMBG16CA-E3/5B meet automotive qualification standards?
Yes, SMBG16CA-E3/5B is AEC-Q101 qualified, having passed rigorous stress tests including high-temperature operating life, temperature cycling, and ESD. This qualification confirms its suitability for automotive applications such as body electronics, ADAS sensor modules, and powertrain control units where long-term reliability under thermal and mechanical stress is mandatory.
What is the thermal resistance of SMBG16CA-E3/5B and why does it matter for PCB layout?
The SMBG16CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal. This value guides thermal design: to maintain TJ ≤150 °C during repeated surges, designers must ensure adequate copper area and avoid excessive ambient temperature rise - especially in sealed enclosures or high-power-density boards.
How does the SMBG (DO-215AA) package of SMBG16CA-E3/5B compare to SMB (DO-214AA) or SMC (DO-214AB) in terms of board space and surge capability?
The SMBG (DO-215AA) package of SMBG16CA-E3/5B measures 4.57 mm × 3.94 mm × 2.10 mm - smaller than SMC (7.11 mm × 6.22 mm) and slightly more compact than standard SMB (4.57 mm × 3.94 mm × 2.31 mm). While it delivers the same 600 W peak pulse power as SMBJ variants, its optimized leadframe supports higher surge current density per unit area, making it preferred for dense automotive and industrial PCB layouts where space and performance are both constrained.
