Product details
Overview
SMBG100CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal and power lines. It features 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SMBG100CAHE3/5B datasheet, SMBG100CAHE3/5B pinout, SMBG100CAHE3/5B application, or SMBG100CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low leakage (<1.0 µA at VWM), thermal resistance (RθJA = 100 °C/W), 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, VC, and IPPM specifications for positive and negative transients. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive 10/1000 µs pulses at 0.01% duty cycle.
The device is rated for TJ = –55 °C to +150 °C, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and is qualified to AEC-Q101 for automotive under-hood and chassis applications - confirming robustness against thermal cycling, humidity, and mechanical stress in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected line. |
| VBR (min/max) | 111 V / 123 V at 1 mA - guaranteed breakdown threshold across production lot; ensures consistent turn-on during overvoltage events. |
| VC @ IPPM | 162 V at 3.7 A - clamped voltage seen by downstream circuitry during 10/1000 µs surge; limits stress on ICs and MOSFETs. |
| PPPM | 600 W - peak pulse power handling capacity; enables protection against high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| ID @ VWM | <1.0 µA - ultra-low reverse leakage at stand-off voltage; avoids signal distortion or bias shift in high-impedance sensor paths. |
| TJ max | +150 °C - maximum junction temperature; supports operation in engine control units and powertrain modules without derating. |
| Package | SMBG (DO-215AA) - surface-mount, low-profile package with matte tin-plated leads; compatible with standard reflow profiles and J-STD-002 solderability. |
Pinout & Package
SMBG100CAHE3/5B uses the SMBG (DO-215AA) package: molded plastic case with two terminals, no polarity marking (bidirectional), and 0.235–0.255 inch (5.97–6.48 mm) body length. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per datasheet Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (symmetrical) | Bidirectional conduction path - either terminal serves as anode or cathode depending on transient polarity; no DC bias dependency. |
| Terminal 2 | Anode/Cathode (symmetrical) | Identical electrical role to Terminal 1; device functions identically regardless of orientation in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain, ADAS, and body electronics - guarantees reliability under temperature cycling, humidity, and vibration stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM (100 V), but lower PPPM = 600 W (same), higher VC = 170 V at 3.5 A; non-AEC-Q101 rated. | Lacks automotive qualification; suitable for industrial/commercial only where AEC-Q101 is not mandated. | Select SMBJ100CA when cost sensitivity outweighs automotive compliance requirements and clamping voltage margin allows 170 V. |
| SMCJ100CA | Same VWM/VBR, but larger SMC (DO-214AB) package; PPPM = 1500 W; VC = 165 V at 9.1 A. | Higher surge capacity suits high-energy environments (e.g., motor drives), but requires larger PCB area and different pad layout. | Choose SMCJ100CA when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger footprint. |
Compared with SMBJ100CA and SMCJ100CA, SMBG100CAHE3/5B uniquely combines AEC-Q101 qualification, SMBG's compact footprint (40% smaller than SMC), and precise 162 V clamping - making it optimal for space-constrained automotive modules requiring certified reliability.

FAQ
What is the clamping voltage of SMBG100CAHE3/5B at its rated peak pulse current?
The SMBG100CAHE3/5B has a maximum clamping voltage (VC) of 162 V at 3.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet Document Number 88456, page 2. The SMBG100CAHE3/5B maintains this clamping performance across its full operating temperature range (–55 °C to +150 °C).
Is SMBG100CAHE3/5B suitable for automotive applications?
Yes, SMBG100CAHE3/5B is AEC-Q101 qualified (per datasheet note on page 3), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its construction - glass-passivated junction, MSL Level 1 rating, and operating temperature range up to +150 °C - meets stringent automotive reliability requirements. The SMBG100CAHE3/5B is explicitly designated for use in automotive systems per Vishay's ordering information and qualification documentation.
What does the "HE3" suffix indicate in SMBG100CAHE3/5B?
The "HE3" suffix in SMBG100CAHE3/5B denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. Per Vishay's mechanical data section (page 1), "Base P/NHE3" means the device meets JESD 201 Class 2 whisker resistance and is rated for automotive-grade reliability. The "5B" indicates packaging in 13-inch diameter tape-and-reel format with 3200 units per reel - distinct from "52" (7-inch reel, 750 units).
How does SMBG100CAHE3/5B differ from unidirectional variants like SMBG100AHE3/5B?
SMBG100CAHE3/5B is bidirectional, meaning it clamps symmetrically for both positive and negative transients, with identical VBR (111–123 V) and VC (162 V) in either polarity. In contrast, SMBG100AHE3/5B is unidirectional, featuring a cathode band and conducting only in reverse bias - requiring correct orientation on PCB. The "CA" suffix explicitly designates bidirectional functionality per Vishay's naming convention in the document introduction.
What is the maximum reverse leakage current for SMBG100CAHE3/5B at its stand-off voltage?
The SMBG100CAHE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at its stand-off voltage (VWM) of 100 V, tested at TA = 25 °C. This low leakage preserves signal integrity in high-impedance circuits such as sensor bias networks and precision analog inputs. The value is specified in the Electrical Characteristics table (page 2) of Vishay Document Number 88456 and applies to both polarities due to the device's bidirectional nature.
