Product details
Overview
SMBG36CAHE3/52 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 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 58.1 V maximum clamping voltage (VC) at 10.3 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 SMBG36CAHE3/52 datasheet, SMBG36CAHE3/52 pinout, SMBG36CAHE3/52 application, or SMBG36CAHE3/52 equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.43), junction temperature range (–55 °C to +150 °C), 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 leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling protection of high-speed analog and digital signal paths without signal distortion.
The device meets MSL Level 1 per J-STD-020 (reflow peak 260 °C), uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and is qualified to AEC-Q101 for automotive under-hood and chassis applications - confirming robustness against thermal cycling, humidity, and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin below circuit operating voltage. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - defines reliable conduction onset across production lot; tight 10.5% tolerance enables predictable protection threshold. |
| VC @ IPPM | 58.1 V at 10.3 A - clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels. |
| PPPM | 600 W - peak transient power dissipation capability; supports repetitive 0.01% duty cycle surges without degradation. |
| ID @ VWM | <1.0 μA - ultra-low leakage ensures minimal standby power loss and no signal loading on high-impedance nodes. |
| TJ Range | –55 °C to +150 °C - extended junction temperature range enables use in engine control units and industrial motor drives. |
| Package | SMBG (DO-215AA) - surface-mount gull-wing package with 0.235" × 0.255" footprint; optimized for automated pick-and-place and reflow soldering. |
Pinout & Package
SMBG36CAHE3/52 is housed in the SMBG (DO-215AA) package: a low-profile, gull-wing leaded plastic case measuring 6.48 mm × 4.57 mm × 2.10 mm (L × W × H), with matte tin-plated terminals solderable per J-STD-002. Bidirectional construction means no polarity marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; symmetrical conduction enables AC line or differential signal protection. |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; no marking required; PCB layout requires no orientation constraint. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and ADAS sensors - guarantees reliability under temperature cycling, humidity, and mechanical shock. |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients from inductive load switching (e.g., solenoid drivers) without failure or parameter shift. |
| Low clamping ratio (VC/VBR = 1.43) | Minimizes overvoltage exposure to protected ICs - critical for safeguarding 3.3 V or 5 V logic interfaces. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning - reduces manufacturing complexity and cost. |
| Glass passivated junction | Ensures stable leakage current and long-term parameter stability across temperature and humidity stress conditions. |

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-E3/52 | Same VWM (36 V), but lower PPPM = 600 W (same), higher VC = 58.1 V (identical), yet rated only to 150 °C TJ max and not AEC-Q101 qualified. | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and full AEC-Q101 validation is unnecessary. |
| 1.5KE36CA | Same VWM/VBR specs, but DO-201 package (axial lead); larger footprint, higher thermal resistance (RθJA ≈ 150 °C/W vs. 100 °C/W), and no MSL Level 1 rating. | Not compatible with automated SMT assembly; limited to through-hole prototyping or legacy repair. | Choose only for manual assembly or replacement in existing DO-201-based designs - not recommended for new SMT production. |
Compared with SMBJ36CA-E3/52 and 1.5KE36CA, SMBG36CAHE3/52 uniquely combines AEC-Q101 qualification, SMBG's compact gull-wing footprint, and MSL Level 1 reflow compatibility - making it the preferred choice for high-volume automotive and industrial SMT production where reliability, manufacturability, and space constraints converge.

FAQ
What is the maximum clamping voltage of SMBG36CAHE3/52 and under what test condition?
The SMBG36CAHE3/52 has a maximum clamping voltage (VC) of 58.1 V, measured at a peak pulse current (IPPM) of 10.3 A using the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and confirms effective overvoltage limitation for protected downstream circuitry.
Is SMBG36CAHE3/52 suitable for automotive applications?
Yes, SMBG36CAHE3/52 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, MSL Level 1 reflow compatibility, and –55 °C to +150 °C operating range - meets stringent automotive reliability requirements for engine control, body electronics, and ADAS sensor protection.
What does the "HE3" suffix indicate in SMBG36CAHE3/52?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. It distinguishes this variant from non-automotive versions (e.g., "E3") and confirms compliance with automotive-grade whisker resistance (JESD201 Class 2) and high-temperature reflow (260 °C peak).
How does SMBG36CAHE3/52 differ from unidirectional SMBG36AHE3/52?
SMBG36CAHE3/52 is bidirectional with symmetrical VBR and VC in both polarities, while SMBG36AHE3/52 is unidirectional and includes a cathode band marking. The "CA" suffix indicates bidirectional operation - essential for AC-coupled or differential signal protection where polarity reversal occurs.
What is the thermal resistance of SMBG36CAHE3/52 and how does it affect power handling?
SMBG36CAHE3/52 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. This value directly limits sustained power dissipation; however, its 600 W peak pulse rating applies only to short-duration transients (≤50 ms), not continuous operation.
