Product details
Overview
SMBJ13CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ13CAHE3_B/I datasheet, SMBJ13CAHE3_B/I pinout, SMBJ13CAHE3_B/I application, or SMBJ13CAHE3_B/I equivalent, this device is selected for robust ESD and surge immunity in automotive-grade (AEC-Q101 qualified), telecom, and industrial control systems where bidirectional transient suppression and low clamping ratio (< 1.67×VWM) are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (< 1.0 µA at VWM), while the 100 °C/W junction-to-ambient thermal resistance supports operation up to +150 °C junction temperature under defined PCB pad conditions.
The device meets MSL Level 1 per J-STD-020, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102, and is halogen-free RoHS-compliant (HE3 suffix denotes AEC-Q101 qualification). It delivers fast response time (< 1.0 ps) and low incremental surge resistance for effective suppression of lightning-induced surges and inductive switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Confirmed minimum/maximum threshold where avalanche conduction initiates reliably. |
| VC (Clamping Voltage) | 21.5 V at 27.9 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; enables downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy handling capability without degradation under standard 10/1000 µs waveform. |
| IPPM (Peak Pulse Current) | 27.9 A - Maximum non-repetitive surge current the device safely diverts away from sensitive nodes. |
| TJmax | +150 °C - Maximum junction temperature enabling use in high-ambient environments like engine control units. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated placement. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals function as anode and cathode depending on applied voltage polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Terminal 1) | Transient current input/output node | Either terminal accepts surge current in either direction; bidirectional symmetry eliminates orientation concerns during layout. |
| Anode/Cathode (Terminal 2) | Transient current return path | Completes low-inductance path to ground or rail; requires direct connection to low-impedance plane for optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional suppression | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 600 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly mounted on 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including body electronics, infotainment, and ADAS sensor interfaces. |
| Low clamping ratio (VC/VWM = 1.65) | Minimizes overvoltage stress on protected ICs compared to higher-ratio alternatives, improving system-level reliability. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free assembly processes without preconditioning or special handling requirements. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 | Same electrical specs and SMB package; commercial-grade (non-AEC-Q101), RoHS-compliant only (no halogen-free or automotive qualification). | Limited to non-automotive industrial or consumer designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive qualification needs and supply chain traceability is less critical. |
| SAC13CA | Same VWM/VC ratings but in smaller SOD-123FL package (lower PPPM = 400 W); not AEC-Q101 qualified. | Suitable only for space-constrained, lower-energy applications (e.g., USB port protection), not motor drive or automotive power rails. | Choose only if board area is severely limited and surge threat level is ≤ Class 3 per IEC 61000-4-5. |
Compared with SMBJ13CAHE3_B/I, the E3/52 variant lacks automotive qualification and halogen-free compliance, while SAC13CA sacrifices 33 % peak power handling and mechanical robustness for footprint reduction - making SMBJ13CAHE3_B/I the sole choice for AEC-Q101–required, high-energy industrial or automotive deployments.

FAQ
What is the clamping voltage of SMBJ13CAHE3_B/I at its rated peak pulse current?
The SMBJ13CAHE3_B/I has a maximum clamping voltage (VC) of 21.5 V at 27.9 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The SMBJ13CAHE3_B/I achieves this clamping performance while maintaining bidirectional symmetry and AEC-Q101 qualification.
Is SMBJ13CAHE3_B/I suitable for automotive applications?
Yes, SMBJ13CAHE3_B/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay's official documentation. It is specifically intended for automotive use cases including body control modules, infotainment systems, and sensor interfaces where reliability under temperature cycling, vibration, and surge stress is required. The SMBJ13CAHE3_B/I meets all applicable stress tests per AEC-Q101 Rev D and supports full traceability for PPAP submissions.
How does the bidirectional design of SMBJ13CAHE3_B/I affect PCB layout?
The bidirectional design of SMBJ13CAHE3_B/I eliminates polarity marking and orientation dependency - both terminals are functionally identical, simplifying placement and reducing assembly errors. Layout requires symmetric, low-inductance connections to ground or rail planes, with recommended 5.0 mm × 5.0 mm copper pads per terminal to sustain 600 W pulse power. No silkscreen polarity indicator is needed, and routing can be optimized for minimal loop area without regard to anode/cathode assignment - a key advantage over unidirectional TVS diodes like SMBJ13AHE3_B/I.
What is the maximum operating temperature for SMBJ13CAHE3_B/I?
The SMBJ13CAHE3_B/I has a maximum junction temperature (TJmax) of +150 °C and an operating ambient range of -55 °C to +150 °C. Its thermal resistance (RθJA) is 100 °C/W under standard mounting conditions, meaning it can dissipate up to 5.0 W continuously at TA = 50 °C. For sustained high-temperature environments such as engine compartments, derating curves in the Vishay datasheet (Fig. 2) must be applied - the SMBJ13CAHE3_B/I remains fully functional and qualified up to its rated TJmax.
Does SMBJ13CAHE3_B/I meet RoHS and halogen-free requirements?
Yes, SMBJ13CAHE3_B/I is RoHS-compliant and halogen-free, as indicated by the "HM3"-derived HE3 suffix and confirmed in Vishay's material categorization documentation (www.vishay.com/doc?99912). The device uses matte tin-plated leads and molding compound meeting UL 94 V-0 flammability rating, with no brominated flame retardants or chlorine-based additives. Compliance is verified per JEDEC J-STD-609A Class 1 and supports environmental requirements for automotive and industrial end equipment - a documented feature of the SMBJ13CAHE3_B/I specification.
