Product details
Overview
SMBG6.0CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG6.0CA-E3/5B datasheet, SMBG6.0CA-E3/5B pinout, SMBG6.0CA-E3/5B application, or SMBG6.0CA-E3/5B equivalent, key selection criteria include bidirectional clamping behavior, low clamping ratio (VC/VBR ≈ 1.47), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, IPPM, and VC specifications for positive and negative transients. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), enabling suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device is rated for TJ = –55 °C to +150 °C, has RθJA = 100 °C/W (on 0.2" × 0.2" pads), and meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance. It is not a voltage regulator or rectifier - its sole function is transient energy diversion via avalanche breakdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Ensures reliable, repeatable avalanche initiation across production lot |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage seen by protected circuit during 600 W surge; defines worst-case stress |
| PPPM | 600 W (10/1000 µs) - Peak transient energy handling capacity under standard surge waveform |
| ID @ VWM | ≤1.0 µA - Ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max. | +150 °C - Enables operation in under-hood automotive or high-ambient industrial environments |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.) |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, gull-wing leads, matte tin-plated, RoHS-compliant (E3 suffix), MSL Level 1 (260 °C peak reflow). No polarity marking on bidirectional variants - terminals are symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path (reversible) | Either terminal accepts transient polarity; no DC bias dependency - ideal for AC lines and differential signals |
| Case (body) | Thermal and mechanical interface | Non-electrical; requires minimum 5.0 mm × 5.0 mm copper pad per terminal for thermal derating compliance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) when properly mounted on recommended PCB pads |
| Low clamping voltage (10.3 V) | Provides 72% overvoltage margin above VWM, protecting 5 V logic and analog ICs with tight VDD tolerance |
| AEC-Q101 qualification | Validates reliability for automotive infotainment, body control modules, and ADAS sensor interfaces |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profile (peak 260 °C) without baking preconditioning |
Applications
| Automotive Sensor Interface | Industrial CAN Bus Protection |
|---|---|
Use Scenario: Protecting LIN or SENT bus lines in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pair or single-ended signal line to clamp transients before they reach MCU input pins. Use Value: Prevents latch-up or gate oxide damage in automotive-grade microcontrollers by limiting voltage to ≤10.3 V during 58.3 A surges. | Use Scenario: Safeguarding CAN transceivers (e.g., TJA1042) against ESD and ISO 7637-2 pulses in factory automation PLCs. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector entry point to shunt surge energy before it propagates onto bus traces. Use Value: Maintains CAN signal integrity with <1.0 µA leakage at 6.0 V, avoiding false dominant states or timing skew in 1 Mbps networks. |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
Use Scenario: Shielding USB 2.0 D+/D− lines in smart home hubs from human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Symmetric TVS placed differentially across data lines to absorb ±8 kV contact discharge per IEC 61000-4-2. Use Value: Sub-1 ns response ensures clamping occurs before ESD pulse couples into PHY, preserving signal eye diagram and link reliability. | Use Scenario: Front-end protection of ADSL/VDSL line drivers in residential gateways subjected to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Primary surge diverter on tip/ring pair, coordinated with gas discharge tube (GDT) for staged protection. Use Value: 600 W rating handles 10/1000 µs surges up to 58.3 A, reducing secondary protector stress and extending system MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/5B | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating) and higher IPPM = 62.0 A; SMBJ package has larger footprint (DO-214AB vs DO-215AA) | Suitable where board space allows larger package and higher surge margin is needed | Select SMBJ6.0CA-E3/5B only if layout accommodates 4.58 mm × 3.94 mm vs SMBG's 4.57 mm × 3.94 mm and thermal design permits higher IPPM |
| 1.5KE6.8CA | Higher PPPM = 1500 W but axial DO-15 package; VBR = 7.14–7.88 V; no AEC-Q101 qualification | Used in non-automotive, high-energy industrial power supplies where through-hole mounting is acceptable | Choose 1.5KE6.8CA only for cost-sensitive, non-SMT, non-automotive designs requiring >600 W capability |
Compared with SMBJ6.0CA-E3/5B and 1.5KE6.8CA, SMBG6.0CA-E3/5B offers optimal balance of compact SMBG footprint, AEC-Q101 compliance, and verified 600 W surge handling - making it preferred for space-constrained automotive and industrial SMT assemblies where qualification and reliability are mandatory.

FAQ
What is the polarity configuration of SMBG6.0CA-E3/5B?
SMBG6.0CA-E3/5B is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients. Unlike unidirectional variants (e.g., SMBG6.0A), it has no cathode band marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or floating signal paths.
Does SMBG6.0CA-E3/5B require a heatsink for 600 W surge handling?
No, SMBG6.0CA-E3/5B does not require an external heatsink for single-event 600 W (10/1000 µs) surges. Its thermal design relies on PCB copper pads (minimum 0.2" × 0.2" per terminal) to absorb and dissipate transient energy. The RθJA = 100 °C/W rating assumes this pad layout; no additional thermal interface is needed for compliance with IEC 61000-4-5 testing conditions.
Is SMBG6.0CA-E3/5B compatible with lead-free reflow processes?
Yes, SMBG6.0CA-E3/5B is RoHS-compliant (E3 suffix) and qualified for lead-free reflow with a maximum peak temperature of 260 °C (MSL Level 1 per J-STD-020). Its matte tin-plated leads meet J-STD-002 solderability requirements, and the package withstands standard SAC305 profiles without degradation to clamping performance or leakage characteristics.
How does the clamping voltage of SMBG6.0CA-E3/5B compare to its breakdown voltage?
SMBG6.0CA-E3/5B has a VBR range of 6.67–7.37 V at 10 mA and a maximum clamping voltage VC of 10.3 V at 58.3 A. This yields a clamping ratio (VC/VBR(min)) of ~1.54 - indicating moderate overvoltage margin during surge events, appropriate for safeguarding 5 V logic rails while maintaining low let-through stress.
Can SMBG6.0CA-E3/5B be used in place of a unidirectional TVS like SMBG6.0A?
No - SMBG6.0CA-E3/5B must not replace unidirectional SMBG6.0A in DC-biased circuits (e.g., power rail protection), because its bidirectional structure conducts in both directions and lacks defined anode/cathode polarity. Using it on a DC line would cause short-circuit failure. Always match TVS polarity to circuit topology: CA for AC/floating, A for DC/unidirectional.
