Product details
Overview
SMBG6.0CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 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), and AEC-Q101 qualified for automotive electronics protection. It clamps transients to ≤10.3 V at 58.3 A peak pulse current and operates from –55 °C to +150 °C.
For engineers reviewing the SMBG6.0CAHE3/5B datasheet, SMBG6.0CAHE3/5B pinout, SMBG6.0CAHE3/5B application, or SMBG6.0CAHE3/5B equivalent, key selection criteria include bidirectional surge immunity, low clamping voltage under 600 W stress, AEC-Q101 qualification, RoHS-compliant HE3 suffix, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device functions as a voltage-clamping protector in parallel with sensitive circuit nodes, responding within picoseconds to ESD and lightning-induced surges. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity concerns in AC-coupled or floating signal lines.
Designed for repetitive transient suppression with 0.01 % duty cycle, it leverages glass-passivated junction technology and low incremental surge resistance to maintain stable clamping across temperature (–55 °C to +150 °C) and surge repetition. Thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system working voltage margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures reliable turn-on before downstream IC damage. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W 10/1000 μs surge; defines worst-case overvoltage seen by protected circuit. |
| PPPM | 600 W - Peak pulse power handling per JEDEC standard; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IPPM | 58.3 A - Peak surge current capability at VC; determines minimum trace width and PCB pad sizing for safe energy dissipation. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments without derating. |

Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing leadframe with matte tin-plated terminals solderable per J-STD-002. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | One terminal of symmetrical PN junction; conducts during positive voltage excursions above VBR. |
| Cathode | Transient current entry (negative half-cycle) | Second terminal of symmetrical PN junction; conducts during negative voltage excursions above |VBR|. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions enables protection of AC signals, differential buses, and ungrounded sensors without polarity constraints. |

| Low clamping ratio (VC/VBR) | 10.3 V / 6.67 V ≈ 1.54 - Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns; eliminates bake requirements pre-assembly. |
Applications
| Automotive CAN Bus Protection | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair in vehicle ECUs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Parallel-connected voltage clamp that diverts surge current away from CAN transceiver inputs. Use Value: Limits transient voltage to ≤10.3 V, preserving CAN transceiver integrity during 600 W surges while maintaining signal integrity due to low junction capacitance (<100 pF at 0 V). | Use Scenario: Shielding analog output (4–20 mA) or digital I/O lines of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional shunt protector placed at sensor connector interface to absorb ESD and inductive switching spikes. Use Value: Prevents latch-up or gate oxide damage in downstream op-amps or microcontrollers by clamping to 10.3 V with sub-nanosecond response time. |
| Consumer Power Adapter Inputs | Telecom Line Interface Circuits |
Use Scenario: Secondary-side transient suppression on DC output rails of wall adapters powering USB-C peripherals. IC Role / Device Role / Timing Role: Low-capacitance TVS across VOUT and GND to suppress fast-rising noise from switching regulator coupling. Use Value: Maintains <10.3 V overvoltage during 58.3 A surges without affecting regulation loop stability due to minimal parasitic capacitance. | Use Scenario: Protecting Ethernet PHY or DSL line drivers from lightning-induced surges entering via RJ-45 jacks. IC Role / Device Role / Timing Role: Bidirectional clamp on differential pairs (e.g., TX+/TX–) to limit common-mode and differential-mode transients. Use Value: Enables compliance with ITU-T K.21 basic protection level using single-device solution with symmetric clamping and AEC-Q101 reliability margin. |
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 | Same VWM (6.0 V), but lower PPPM = 600 W (same rating), slightly higher VC = 10.5 V at 58.1 A; non-AEC-Q101, MSL Level 1 still applies. | Not qualified for automotive use; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMBJ6.0CA only if automotive qualification is unnecessary and cost is prioritized over extended reliability validation. |
| SAC5.0 | Lower VWM = 5.0 V, VC = 9.2 V at 65.2 A, same PPPM = 600 W; AEC-Q101 qualified; smaller SOD-123FL package (lower IPPM derating at high TA). | Better suited for space-constrained layouts and lower-voltage logic rails (e.g., 3.3 V MCU I/O), but less margin for 6 V nominal systems. | Choose SAC5.0 when board area is critical and system VCC is ≤5.5 V; avoid in 6 V nominal circuits due to insufficient VWM margin. |
Compared with SMBJ6.0CA and SAC5.0, SMBG6.0CAHE3/5B uniquely combines AEC-Q101 qualification, 6.0 V VWM headroom for 6 V systems, and SMBG package thermal performance-making it optimal for automotive and high-reliability industrial surge protection where layout space and qualification rigor are both required.

FAQ
What is the maximum clamping voltage of SMBG6.0CAHE3/5B under full-rated surge conditions?
The SMBG6.0CAHE3/5B clamps to a maximum of 10.3 V when subjected to its rated 600 W peak pulse power (10/1000 μs waveform) at 58.3 A peak current. This value is measured per JEDEC test conditions and represents the worst-case overvoltage imposed on protected circuitry during surge events.
Is SMBG6.0CAHE3/5B suitable for automotive applications?
Yes, SMBG6.0CAHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its qualification covers temperature cycling, high-temperature operating life, and ESD robustness-making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
How does the HE3 suffix affect SMBG6.0CAHE3/5B's compliance and performance?
HE3 denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. It does not alter electrical specs but confirms enhanced process control and automotive-grade reliability versus base E3 or M3 variants.
What is the thermal resistance of SMBG6.0CAHE3/5B, and how does it impact PCB layout?
SMBG6.0CAHE3/5B 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. To maintain safe junction temperatures during repetitive surges, designers must provide adequate copper area and avoid excessive trace length between device terminals and ground/power planes.
Can SMBG6.0CAHE3/5B be used in bidirectional signal paths like RS-485 or CAN?
Yes, SMBG6.0CAHE3/5B is specifically designed for bidirectional protection and exhibits symmetrical VBR and VC characteristics in both polarities. Its low clamping voltage (10.3 V), fast response, and absence of polarity marking make it ideal for differential bus protection such as CAN, RS-485, and LVDS interfaces.
