Product details
Overview
SMBG100CA-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 100 V standoff voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power dissipation with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the SMBG100CA-E3/5B datasheet, SMBG100CA-E3/5B pinout, SMBG100CA-E3/5B application, or SMBG100CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This device operates as a voltage-clamped surge protector, responding within picoseconds to transients induced by inductive switching or ESD events. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity concerns during layout - critical for AC-coupled or differential signal paths.
The SMBG100CA-E3/5B uses a glass-passivated silicon junction and is rated for repetitive 0.01% duty cycle surges. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation under sustained transient stress when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates; defines safe signal swing range for protected line |
| VBR (min/max) | 111 V / 123 V at 1 mA - guaranteed breakdown threshold across production lot; ensures consistent turn-on timing |
| VC @ IPPM | 162 V at 3.7 A - clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream IC |
| PPPM | 600 W - peak pulse power handling capacity; validates compliance with IEC 61000-4-5 Level 4 surge immunity |
| TJ max | +150 °C - maximum junction temperature; supports operation in under-hood automotive or high-ambient industrial environments |
| MSL Level | Level 1 per J-STD-020 - no floor life limitation; enables indefinite storage and standard reflow without baking |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals serve identically as clamping nodes; no cathode band marking required for bidirectional types |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded sensor outputs without polarity constraints |
| 600 W peak pulse power | Meets IEC 61000-4-5 surge test requirements up to 4 kV (line-earth) with margin when used with appropriate series impedance |
| Glass passivated junction | Ensures stable leakage current (<1.0 μA at VWM) and long-term reliability under thermal cycling and humidity exposure |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules, ADAS sensors, and body electronics |
| MSL Level 1 rating | Supports direct placement into high-volume SMT lines without dry-pack or baking steps - reduces manufacturing overhead |
Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine bays or chassis modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector entry point to shunt transients before reaching signal conditioning amplifier or ADC input.

IC Role / Device Role / Timing Role: Secondary clamping device downstream of primary MOV or fuse, limiting let-through voltage to protect PMIC and level shifters. Use Value: 162 V clamping voltage ensures downstream 5 V/3.3 V regulators remain within absolute maximum ratings during EN 61000-4-5 testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA-E3/5B | Same VWM (100 V), lower PPPM (600 W same), but higher VC (170 V vs. 162 V); SMBJ package has larger footprint (DO-214AB) | Less space-constrained layouts where thermal mass improves surge endurance; not drop-in due to different pad layout | Select SMBJ100CA-E3/5B only if board redesign accommodates larger 7.0 mm × 6.2 mm footprint and higher clamping voltage is acceptable |
| SMCJ100CA-E3/5B | Same VWM, higher PPPM (1500 W), higher VC (179 V); SMC package (DO-214AB) larger than SMBG | Higher-energy surge environments (e.g., outdoor telecom cabinets); requires PCB area increase and thermal derating review | Choose SMCJ100CA-E3/5B when system-level testing exceeds 600 W surge requirement and board space allows 7.5 mm × 6.5 mm footprint |

FAQ
What is the clamping voltage of SMBG100CA-E3/5B at its rated peak pulse current?
The SMBG100CA-E3/5B has a maximum clamping voltage (VC) of 162 V at its specified peak pulse current (IPPM) of 3.7 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across temperature and production lot, ensuring predictable protection margin for downstream circuitry in the SMBG100CA-E3/5B design.
Is SMBG100CA-E3/5B suitable for automotive applications?
Yes, the SMBG100CA-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and chassis-mounted modules. Its 150 °C maximum junction temperature, MSL Level 1 rating, and glass-passivated junction meet stringent automotive reliability requirements - making it a validated choice for protecting CAN, LIN, and sensor interfaces in the SMBG100CA-E3/5B application space.
Does SMBG100CA-E3/5B have polarity markings on the package?
No, the SMBG100CA-E3/5B is a bidirectional TVS diode and carries no polarity marking such as a cathode band. Both terminals are functionally identical, allowing flexible PCB layout without orientation constraints - a key distinction from unidirectional variants like SMBG100A-E3/5B, where the band denotes the cathode end.
What is the maximum reverse leakage current for SMBG100CA-E3/5B at its standoff voltage?
At its 100 V standoff voltage (VWM) and 25 °C ambient temperature, the SMBG100CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage preserves signal integrity and minimizes power loss in high-impedance sensing circuits, confirming stable performance in the SMBG100CA-E3/5B's intended operating range.
What package type does SMBG100CA-E3/5B use, and what are its key mechanical features?
The SMBG100CA-E3/5B uses the SMBG (DO-215AA) package: a low-profile, gull-wing surface-mount outline measuring 4.57 mm × 3.94 mm × 2.16 mm. Key features include matte tin-plated leads compliant with J-STD-002, UL 94 V-0 molding compound, and compatibility with standard reflow profiles - all verified for the SMBG100CA-E3/5B in its official Vishay documentation.
