Product details
Overview
SMBG5.0C-E3/5B from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or power lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤9.2 V at 65.2 A peak surge current. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the SMBG5.0C-E3/5B datasheet, SMBG5.0C-E3/5B pinout, SMBG5.0C-E3/5B application, or SMBG5.0C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, low clamping voltage under 65 A surge, RoHS-compliant matte tin terminals, MSL Level 1 reflow compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping across temperature (–55 °C to +150 °C).
The device meets UL 94 V-0 flammability requirements and is rated for 600 W peak pulse power per 10/1000 µs waveform at 0.01% duty cycle. Thermal resistance is 100 °C/W junction-to-ambient (on 5.0 mm × 5.0 mm copper pads), supporting robust thermal performance in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 5 V systems. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Ensures reliable turn-on above normal operating voltage while avoiding false triggering. |
| VC @ IPPM | ≤9.2 V at 65.2 A - Clamping voltage limits stress on downstream ICs during ESD or load-dump events. |
| PPPM | 600 W (10/1000 µs) - Sustains high-energy transients common in automotive and industrial environments. |
| TJ max | +150 °C - Enables operation in under-hood automotive locations and high-temperature industrial enclosures. |
| MSL Level | Level 1 (260 °C peak) - Supports standard lead-free reflow without preconditioning or dry-pack requirements. |
Pinout & Package
Package: DO-215AA (SMBG), surface-mount, gull-wing leads, no polarity marking (bi-directional configuration). Dimensions: 4.57 mm × 3.94 mm × 2.10 mm (L × W × H); cathode band omitted per bi-directional design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No polarity marking; either terminal serves as anode or cathode depending on transient polarity - simplifies PCB layout and eliminates orientation errors. |
| Lead 1 / Lead 2 | Current-carrying terminals | Matte tin-plated, solderable per J-STD-002/JESD22-B102; supports automated placement and reflow with JESD201 Class 1A whisker resistance (E3 suffix). |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Identical VBR and VC in both directions - protects AC-coupled or differential signal lines (e.g., CAN, LIN, sensor bridges) without polarity constraints. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces - ensures reliability under thermal cycling, vibration, and humidity stress. |
| 600 W peak pulse rating | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and IEC 61000-4-5 surge events without degradation - reduces need for secondary protection stages. |
| Glass passivated junction | Improves long-term stability and leakage control vs. epoxy-passivated alternatives - maintains <800 µA ID at VWM over lifetime in harsh environments. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine compartments subject to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between sensor output and microcontroller ADC input. Use Value: Limits transient excursions to ≤9.2 V, preserving ADC integrity and preventing latch-up in 5 V rail systems. | Use Scenario: Shielding 24 V PLC digital input channels from inductive kickback when switching solenoids or relays. IC Role / Device Role / Timing Role: Primary transient suppressor across input terminals, upstream of optocoupler or Schmitt trigger interface. Use Value: Absorbs 600 W surges without derating, enabling direct connection to field wiring without additional RC filtering. |
| USB/Serial Data Line Protection | Power Supply Rail Clamp |
Use Scenario: Safeguarding RS-485 transceivers or USB PHY lines against ESD and cable discharge events in factory automation equipment. IC Role / Device Role / Timing Role: Low-capacitance bi-directional TVS placed differential across data pair (e.g., A/B lines). Use Value: Sub-10 V clamping preserves signal integrity for 3.3 V/5 V logic levels while meeting IEC 61000-4-2 Level 4 (±15 kV contact). | Use Scenario: Secondary overvoltage clamp on 5 V DC-DC output rails feeding sensitive MCU or memory subsystems. IC Role / Device Role / Timing Role: Fast-acting shunt device triggered only during overvoltage faults exceeding 6.4 V. Use Value: Prevents brownout or reset failures by clamping supply spikes before they propagate to load circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA-E3/5B | Same VWM (5.0 V), slightly higher VBR (6.7–7.4 V), identical PPPM (600 W), same DO-214AA (SMB) package but different mechanical outline (DO-214AA vs. DO-215AA). | DO-214AA has wider lead spacing (2.59 mm vs. 2.10 mm) and larger body - requires PCB footprint change. | Select when existing design uses SMBJ footprint or when higher VBR margin is preferred for noise immunity. |
| 1.5KE5.0CA | Same VWM/VBR range, 1500 W PPPM, axial DO-201AD package - significantly larger and not surface-mount compatible. | Designed for through-hole prototyping or legacy board upgrades; unsuitable for automated SMT assembly. | Choose only for manual assembly, high-energy single-event protection, or where board space allows axial components. |
Compared with SMBJ5.0CA-E3/5B and 1.5KE5.0CA, the SMBG5.0C-E3/5B offers optimal balance of compact DO-215AA footprint, AEC-Q101 qualification, and precise 5.0 V system-level clamping - making it the preferred choice for new automotive and space-constrained industrial designs requiring bi-directional SMT TVS protection.

FAQ
What does the "C" suffix indicate in SMBG5.0C-E3/5B?
The "C" suffix denotes bi-directional configuration, meaning the SMBG5.0C-E3/5B provides symmetrical clamping in both polarities - unlike uni-directional variants (e.g., SMBG5.0A) that require correct orientation. This eliminates polarity marking on the SMBG5.0C-E3/5B package and simplifies layout for AC-coupled or differential signals.
Is SMBG5.0C-E3/5B suitable for automotive applications?
Yes, SMBG5.0C-E3/5B is AEC-Q101 qualified and rated for –55 °C to +150 °C junction temperature. Its DO-215AA package, glass-passivated junction, and 600 W surge capability make it appropriate for under-hood and chassis-mounted automotive systems, including sensor protection and infotainment power rails.
How does SMBG5.0C-E3/5B differ from SMBG5.0A-E3/5B?
SMBG5.0C-E3/5B is bi-directional with no polarity marking and identical electrical behavior in both directions, whereas SMBG5.0A-E3/5B is uni-directional with a cathode band and conducts only in reverse bias. The SMBG5.0C-E3/5B's clamping occurs regardless of transient polarity, making it ideal for differential or AC signal paths.
What is the maximum clamping voltage of SMBG5.0C-E3/5B at rated surge current?
The SMBG5.0C-E3/5B clamps to a maximum of 9.2 V at its rated peak pulse current of 65.2 A (10/1000 µs waveform). This value is guaranteed per the Vishay datasheet and ensures downstream 5 V logic remains within safe operating limits during transient events.
Does SMBG5.0C-E3/5B require special PCB layout considerations?
Yes - mount SMBG5.0C-E3/5B on minimum 5.0 mm × 5.0 mm copper pads per terminal to achieve specified thermal resistance (100 °C/W) and 600 W pulse rating. Avoid narrow traces; use short, direct connections to protected nodes to minimize inductance and preserve clamping speed.
