Product details
Overview
SMBG5.0C-E3/52 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), <9.2 V clamping voltage at 65.2 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG5.0C-E3/52 datasheet, SMBG5.0C-E3/52 pinout, SMBG5.0C-E3/52 application, or SMBG5.0C-E3/52 equivalent, key selection considerations include bi-directional surge protection capability, low clamping ratio (VC/VBR ≈ 1.37), RoHS-compliant E3 termination, 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 bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical V-I characteristics enable identical clamping performance in both polarities, making it suitable for AC-coupled or floating signal lines where polarity reversal may occur.
The SMBG5.0C-E3/52 is rated for 150 °C maximum junction temperature and exhibits 100 °C/W junction-to-ambient thermal resistance when mounted per recommended pad layout. It meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 for transient protector classification.

|---|---|
Use Scenario: Protecting wheel speed, crankshaft, or camshaft position sensors exposed to load dump and inductive switching noise in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional TVS placed across sensor output line and ground to clamp ±100 V transients before they reach the MCU ADC input. Use Value: Prevents latch-up or permanent damage to 5 V analog front-end circuitry while maintaining signal integrity due to low capacitance (<100 pF at 0 V). |
Use Scenario: Safeguarding RS-485 transceivers in factory automation networks subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Placed differentially between A/B lines and common-mode to ground to absorb common-mode transients without disrupting data timing. Use Value: Enables >1 Mbps data rates by limiting clamping overshoot to <9.2 V - well below RS-485 receiver common-mode range (−7 V to +12 V). |
| Consumer USB Port ESD | Power Supply Input Clamp |
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D− lines in set-top boxes or smart displays after primary TVS or polymer fuse. IC Role / Device Role / Timing Role: Fast-response bi-directional clamp absorbing ±15 kV contact discharge (IEC 61000-4-2) across differential pair. Use Value: Adds <1 ns response time and <9.2 V clamping to complement slower primary protectors - prevents data corruption during hot-plug events. |
Use Scenario: Input-stage transient suppression on 5 V DC-DC converter inputs in PoE-powered devices or IoT gateways. IC Role / Device Role / Timing Role: Shunt-connected across input capacitor to divert 600 W surge energy away from regulator pass transistor and feedback network. Use Value: Maintains regulation during 10/1000 µs surges by limiting input rail excursion to ≤9.2 V - avoids brownout reset or overvoltage shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | Same VWM (5.0 V), slightly higher VBR (6.4–7.25 V), identical PPPM (600 W), same DO-214AA package but larger footprint (7.0 mm × 6.2 mm vs. SMBG's 4.57 mm × 3.94 mm) | Less space-constrained designs; lower thermal resistance (RθJA = 65 °C/W vs. 100 °C/W) allows higher ambient operation | Select SMBJ5.0CA only if PCB layout permits larger package and thermal budget exceeds 100 °C/W requirement |
| 1.5KE6.8CA | Higher PPPM (1500 W), axial-leaded DO-201AD package, VWM = 5.8 V, VC = 10.5 V at 143 A - not surface-mountable | Prototyping or through-hole legacy designs; unsuitable for automated SMT assembly or high-density layouts | Choose 1.5KE6.8CA only for manual assembly or repair scenarios where board real estate and reflow compatibility are not constraints |
Compared with SMBG5.0C-E3/52, SMBJ5.0CA offers better thermal performance in less dense layouts, while 1.5KE6.8CA delivers higher surge capacity at the cost of SMT incompatibility - neither is pin-compatible, and both require PCB redesign for substitution.

FAQ
What does the "C" suffix indicate in SMBG5.0C-E3/52?
The "C" suffix in SMBG5.0C-E3/52 denotes bi-directional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike uni-directional variants (e.g., SMBG5.0A), SMBG5.0C-E3/52 has no cathode marking and functions identically regardless of voltage polarity applied - essential for protecting AC-coupled or floating signal paths. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Is SMBG5.0C-E3/52 suitable for protecting a 5 V microcontroller I/O line?
Yes, SMBG5.0C-E3/52 is appropriate for 5 V microcontroller I/O protection: its 5.0 V stand-off voltage (VWM) aligns with nominal 5 V rail operation, and its 9.2 V clamping voltage at 65.2 A ensures downstream logic remains within absolute maximum ratings during transients. The device's sub-nanosecond response time and low leakage (<800 µA at VWM) prevent interference with normal signal integrity - verified in Vishay Document Number 88456, Table on page 2.
Does SMBG5.0C-E3/52 meet automotive qualification standards?
Yes, SMBG5.0C-E3/52 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 12-Nov-12 (Document Number 88456), Section "MECHANICAL DATA". This qualification covers stress tests including temperature cycling, humidity bias, and high-temperature operating life - validating suitability for under-hood and chassis-mounted automotive electronics such as body control modules and sensor interfaces.
What is the thermal resistance of SMBG5.0C-E3/52, and how does it affect layout?
SMBG5.0C-E3/52 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, as specified in the "THERMAL CHARACTERISTICS" table on page 3 of the Vishay datasheet. This value requires adherence to the recommended pad layout - reducing copper area increases thermal impedance and risks exceeding the 150 °C maximum junction temperature during repetitive surge events.
How does the E3/52 packaging designation impact assembly?
The "E3/52" suffix indicates RoHS-compliant matte tin plating (E3) and packaging in 7" diameter plastic tape and reel with 750 units per reel (52). The E3 finish meets JESD 201 Class 1A whisker resistance, ensuring reliability in high-vibration environments, while the 7" reel format supports standard SMT pick-and-place equipment with verified feed reliability - detailed in the "ORDERING INFORMATION" section on page 3 of Vishay Document Number 88456.
