Product details
Overview
SMBJ13CAHE3_A/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 signal or power lines. It features a 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), making it suitable for protecting MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ13CAHE3_A/I datasheet, SMBJ13CAHE3_A/I pinout, SMBJ13CAHE3_A/I application, or SMBJ13CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.65), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the SMB package provides thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).
The SMBJ13CAHE3_A/I meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards. It is rated for repetitive 0.01% duty cycle pulses and supports operating junction temperatures from –55 °C to +150 °C, with derating above 25 °C per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR min / max | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown voltage range ensures reliable triggering across process variation. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamping voltage under 10/1000 µs surge limits protected circuit stress to safe levels. |
| PPPM | 600 W - Peak pulse power handling capacity determines survivability against lightning-induced or inductive-switching transients. |
| IPPM | 27.9 A - Peak surge current rating directly maps to transient energy absorption (E ≈ 0.5 × VC × IPPM × tp). |
| TJ max | +150 °C - Maximum junction temperature enables operation in high-ambient industrial environments without thermal shutdown. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation or bake requirement prior to reflow; supports standard SMT assembly. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode (symmetrical) | Bidirectional avalanche junction | No polarity marking required; identical clamping behavior in either direction - simplifies layout and eliminates orientation errors. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - supports use in under-hood and ADAS sensor modules. |
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly laid out with 5.0 mm × 5.0 mm copper pads. |
| Clamping ratio VC/VWM = 1.65 | Minimizes overvoltage exposure during clamping - critical for safeguarding 3.3 V or 5 V logic interfaces downstream. |
| Low incremental surge resistance | Reduces VC overshoot during fast-rising transients (<1 ns response), improving protection fidelity for high-speed data lines. |
| UL 497B recognized (QVGQ2) | Meets safety agency requirements for telecom and industrial surge protectors - reduces certification effort for end equipment. |
Applications
| Industrial Motor Control | Automotive Sensor Interface |
|---|---|
|
Use Scenario: Protecting gate drivers and feedback signal lines in variable-frequency drives subjected to inductive kickback from contactor switching. IC Role / Device Role: Bidirectional clamping element placed across motor phase outputs and isolated analog sensing paths. Use Value: Limits transient voltage to ≤21.5 V during 27.9 A surges, preventing latch-up or oxide damage in 12 V–24 V control ICs. |
Use Scenario: Shielding LIN bus transceivers and MEMS pressure sensor outputs in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role: Primary TVS on differential signal pair and supply rail inputs of automotive-grade sensor ASICs. Use Value: AEC-Q101 qualification and –55 °C to +150 °C operation ensure robustness across full automotive temperature range. |
| Telecom Power Feeds | Consumer USB-C Port Protection |
|
Use Scenario: Safeguarding PoE-powered Ethernet switch ports against lightning-induced common-mode surges on 48 V DC feed lines. IC Role / Device Role: Secondary-level TVS on DC input stage, coordinated with primary GDT or MOV-based protection. Use Value: 13 V VWM allows direct placement after DC-DC converter output, clamping residual transients before downstream regulators. |
Use Scenario: Guarding USB-C CC and VBUS lines in portable chargers against ESD and hot-plug induced transients. IC Role / Device Role: Low-capacitance bidirectional clamp on high-speed data and power pins with minimal signal distortion. Use Value: SMB footprint enables dense layout; clamping at 21.5 V prevents damage to 20 V-rated USB PD controllers without sacrificing speed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VC/PPPM, RoHS-compliant but not automotive-qualified. | Limited to non-automotive industrial or consumer use where qualification is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle assurance. |
| SMCJ13CAHE3_A/I | Same electrical specs but in larger SMC (DO-214AB) package - higher thermal mass, RθJA = 40 °C/W vs. 100 °C/W. | Better suited for high-repetition-rate surges or elevated ambient temperatures (>85 °C). | Choose when board space permits and thermal performance under sustained surge duty is prioritized over footprint size. |
Compared with SMBJ13CAHE3_A/I, the E3/52 variant lacks AEC-Q101 validation and long-term automotive traceability, while the SMCJ13CAHE3_A/I offers superior thermal dissipation at the cost of 30% larger PCB area - enabling trade-offs between reliability assurance, thermal headroom, and miniaturization.

FAQ
What does the "CA" suffix indicate in SMBJ13CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration, meaning the SMBJ13CAHE3_A/I provides symmetrical clamping in both forward and reverse directions. This eliminates polarity concerns during PCB layout and enables protection of AC-coupled or differential signal lines without external circuitry - unlike unidirectional variants (e.g., SMBJ13A) that require correct cathode orientation.
Is SMBJ13CAHE3_A/I compatible with lead-free reflow processes?
Yes, SMBJ13CAHE3_A/I is fully compatible with lead-free reflow soldering. It meets J-STD-020 MSL Level 1 specifications with a maximum peak reflow temperature of 260 °C, and its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards - ensuring reliable wetting and joint integrity in standard Pb-free profiles.
How does the clamping voltage of SMBJ13CAHE3_A/I compare to its standoff voltage?
The SMBJ13CAHE3_A/I has a 13 V standoff voltage (VWM) and a maximum clamping voltage (VC) of 21.5 V at 27.9 A. This yields a clamping ratio of 1.65, indicating moderate overvoltage margin during surge events - sufficient for protecting 15 V-rated components but requiring coordination with upstream filtering for sensitive 3.3 V or 5 V circuits.
Can SMBJ13CAHE3_A/I be used in place of a unidirectional TVS like SMBJ13A?
No - SMBJ13CAHE3_A/I is bidirectional and lacks polarity marking, whereas SMBJ13A is unidirectional with a defined cathode band. Substituting SMBJ13CAHE3_A/I for SMBJ13A may compromise protection in DC-biased circuits where reverse conduction must be blocked; always verify circuit topology and bias conditions before interchange.
What is the significance of the "HE3" and "_A/I" suffixes in SMBJ13CAHE3_A/I?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification, while "_A/I" specifies packaging: "I" denotes 13-inch tape-and-reel delivery (3200 units per reel). Together, SMBJ13CAHE3_A/I identifies an automotive-grade, bidirectional TVS supplied in high-volume SMT-ready format - distinct from commercial (E3) or halogen-free (HM3) variants.
