Product details
Overview
SMBG36CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 10.3 A peak pulse current (IPPM), and 58.1 V maximum clamping voltage (VC) - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG36CA-E3/5B datasheet, SMBG36CA-E3/5B pinout, SMBG36CA-E3/5B application, or SMBG36CA-E3/5B equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C junction temperature rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped bidirectional protector: under normal conditions it presents high impedance (>1 μA leakage at 36 V), but triggers into low-impedance conduction when transient voltage exceeds its 40.0–44.2 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns).
Designed for repetitive surge immunity, SMBG36CA-E3/5B sustains 600 W peak pulse power per 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - defines precise turn-on threshold window for bidirectional surge suppression |
| VC @ IPPM | 58.1 V at 10.3 A - clamping voltage during 600 W transient, limiting downstream IC stress |
| PPPM | 600 W - peak surge power handling capability with standard 10/1000 μs waveform |
| IPPM | 10.3 A - maximum non-repetitive surge current the device safely conducts without failure |
| TJ max. | +150 °C - maximum junction temperature, supporting under-hood automotive and industrial environments |
| MSL Level | Level 1 (J-STD-020) - no floor life limitation; safe for reflow up to 260 °C peak |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing leadframe with matte tin-plated terminals solderable per J-STD-020 and JESD 22-B102. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surges when properly mounted on 5.0 mm × 5.0 mm copper pads |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow without baking or special handling |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role: Bidirectional clamping element placed directly at connector entry point before signal conditioning circuitry.

IC Role / Device Role: Low-capacitance bidirectional clamp across differential signal lanes near connectors. Use Value: Delivers <10 pF junction capacitance (typ.) at zero bias, minimizing signal integrity impact while passing IEC 61000-4-2 ±15 kV contact discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA-E3/5B | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating) and higher IPPM = 10.3 A (identical); differs only in package outline (SMB vs. SMBG - 0.096 g vs. 0.096 g, same pad layout) | SMBJ36CA-E3/5B uses SMB (DO-214AA) package; slightly larger body but identical thermal derating and mounting footprint compatibility | Select SMBG36CA-E3/5B for tighter board space or where DO-215AA mechanical fit is specified; choose SMBJ36CA-E3/5B if legacy SMB footprint is fixed. |
| 1.5KE36CA | Higher PPPM = 1500 W, larger DO-201AE package, slower response due to higher junction capacitance, not AEC-Q101 qualified | Used in AC mains or high-energy industrial surge protectors; unsuitable for automotive or high-speed data lines | Use only where energy absorption >600 W is required and AEC-Q101 compliance is not mandatory; not drop-in compatible due to package and reliability differences. |
Compared with SMBJ36CA-E3/5B, SMBG36CA-E3/5B offers identical electrical performance in a marginally smaller DO-215AA outline optimized for dense layouts; versus 1.5KE36CA, it trades raw energy capacity for automotive qualification, faster response, and surface-mount compatibility - making it the preferred choice for modern automotive and industrial PCB designs.

FAQ
What is the clamping voltage of SMBG36CA-E3/5B at its rated peak pulse current?
The SMBG36CA-E3/5B has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 10.3 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures downstream circuitry remains protected below critical voltage thresholds. The SMBG36CA-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG36CA-E3/5B suitable for automotive applications?
Yes, SMBG36CA-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C. The SMBG36CA-E3/5B meets stringent automotive reliability requirements without derating in typical under-hood thermal environments.
Does SMBG36CA-E3/5B have polarity markings?
No, SMBG36CA-E3/5B is a bidirectional TVS diode and carries no polarity marking on the package. Both terminals are functionally identical, providing symmetrical clamping in either direction - essential for protecting AC-coupled or differential signal lines. This distinguishes it from unidirectional variants like SMBG36A-E3/5B, which feature a cathode band.
What is the maximum reverse leakage current for SMBG36CA-E3/5B at its stand-off voltage?
At its rated stand-off voltage (VWM) of 36 V and ambient temperature of 25 °C, the SMBG36CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage preserves signal integrity in high-impedance circuits and avoids false triggering in precision analog or logic interfaces. The SMBG36CA-E3/5B maintains this specification across its full operational temperature range.
What package type does SMBG36CA-E3/5B use, and what are its key mechanical features?
SMBG36CA-E3/5B uses the SMBG (DO-215AA) surface-mount package: a low-profile gull-wing leadframe with 0.096 g unit weight, UL 94 V-0 molding compound, and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its compact 2.10 mm × 1.96 mm body and 5.97 mm × 4.57 mm overall footprint enable high-density PCB layouts. The SMBG36CA-E3/5B is optimized for automated pick-and-place and lead-free reflow up to 260 °C.
