Product details
Overview
SMBG60CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal or power lines. It features 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), <100 ns response time, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG60CAHE3/5B datasheet, SMBG60CAHE3/5B pinout, SMBG60CAHE3/5B application, or SMBG60CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, 60 V working voltage compatibility with 12 V/24 V automotive systems, low clamping voltage (96.8 V at IPPM), RoHS-compliant AEC-Q101 qualification, and SMBG package thermal performance (RθJA = 100 °C/W).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device complies with ANSI/IEEE C62.35 for surge suppression and meets J-STD-020 MSL Level 1 (260 °C peak reflow), supporting automated SMT assembly. Thermal resistance values (RθJA = 100 °C/W, RθJL = 20 °C/W) are measured on 0.2" × 0.2" copper pads, defining layout-dependent power derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; matches 12 V/24 V automotive bus nominal levels with margin. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures reliable turn-on during transients while avoiding false triggering. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage limits downstream IC stress during 600 W 10/1000 µs surges. |
| PPPM | 600 W - Peak pulse power rating defines maximum transient energy absorption capability per IEC 61000-4-5. |
| IPPM | 6.2 A - Peak pulse current corresponding to 600 W at 96.8 V clamping; used for PCB trace sizing and fuse coordination. |
| TJ max | +150 °C - Maximum junction temperature enables operation in under-hood automotive environments. |
| Qualification | AEC-Q101 - Validated for automotive-grade reliability including temperature cycling, humidity bias, and surge endurance. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical junction; accepts surge current in either direction during overvoltage events. |
| Cathode | Transient current entry (positive polarity) | Second terminal of symmetrical junction; completes bidirectional conduction path with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, LIN), or ungrounded power rails without polarity concerns. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surges on 50 Ω/42 Ω coupling networks when properly laid out. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes voltage overshoot during clamping, reducing stress on protected MOSFETs, microcontrollers, and transceivers. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profiles up to 260 °C peak, simplifying manufacturing logistics. |
Applications
| Automotive Power Line Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients.

Use Value: Passes USB-IF ESD compliance testing (±15 kV air, ±8 kV contact) without degrading 480 Mbps signal rise/fall times. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM (60 V), lower PPPM (600 W same), but SMB (DO-214AA) package (larger footprint, higher RθJA = 125 °C/W) | Less suitable for space-constrained automotive modules; requires larger pad layout for thermal management. | Select SMBJ60CA only if existing PCB uses SMB footprint and thermal budget allows higher junction rise. |
| SMCJ60CA | Same VWM and bidirectional function, but SMC (DO-214AB) package with 1500 W PPPM and higher IPPM (24.3 A) | Over-specified for typical 12 V automotive surges; occupies ~2.5× PCB area of SMBG. | Choose SMCJ60CA only when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires extended lifetime under repetitive stress. |
Compared with SMBJ60CA and SMCJ60CA, SMBG60CAHE3/5B delivers identical clamping performance in a smaller, thermally optimized SMBG package with AEC-Q101 qualification-making it the preferred choice for next-generation automotive and space-sensitive industrial designs requiring validated reliability and minimal board area.

FAQ
What is the exact breakdown voltage range for SMBG60CAHE3/5B?
The SMBG60CAHE3/5B has a guaranteed breakdown voltage (VBR) range of 66.7 V to 73.7 V at 1 mA test current, as specified in the Vishay datasheet (Document Number: 88456, Rev. 09-Jan-2024). This range ensures consistent clamping behavior across production lots while maintaining safe margin above its 60 V stand-off voltage.
Is SMBG60CAHE3/5B suitable for automotive applications?
Yes, SMBG60CAHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature-meets requirements for engine control, body electronics, and ADAS subsystems per ISO 16750 and ISO 7637 standards.
What does the "HE3" suffix indicate in SMBG60CAHE3/5B?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. Per Vishay's ordering nomenclature, HE3 identifies the industrial-grade, automotive-qualified variant (vs. E3 for standard RoHS or HM3 for halogen-free AEC-Q101), ensuring traceability and reliability validation for mission-critical designs.
How does SMBG60CAHE3/5B differ from unidirectional SMBG60AHE3/5B?
SMBG60CAHE3/5B is bidirectional with symmetrical clamping in both polarities and no cathode band marking, whereas SMBG60AHE3/5B is unidirectional with cathode identification and only clamps positive transients. The "CA" suffix confirms bidirectional functionality, critical for protecting AC-coupled or differential interfaces like CAN or RS-485 where polarity is undefined.
What is the maximum clamping voltage of SMBG60CAHE3/5B under surge conditions?
The SMBG60CAHE3/5B clamps to a maximum of 96.8 V at its rated peak pulse current (IPPM = 6.2 A) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
