Product details
Overview
SMBJ130CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 A peak pulse current (IPPM) under 10/1000 µs waveform, and 600 W peak pulse power dissipation - deployed to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom equipment.
For engineers reviewing the SMBJ130CAHE3/5B datasheet, SMBJ130CAHE3/5B pinout, SMBJ130CAHE3/5B application, or SMBJ130CAHE3/5B equivalent, this device serves as a robust, AEC-Q101-qualified transient suppressor for bidirectional DC bus protection, automotive body electronics, and high-reliability industrial I/O circuits where low clamping voltage and fast response (<1 ps) 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 20 °C/W junction-to-lead thermal resistance supports reliable surge energy handling without external heatsinking under standard PCB pad layouts.
The device complies with ANSI/IEEE C62.35 for transient suppressors and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). Its 0.108 %/°C temperature coefficient of VBR enables predictable clamping performance across –55 °C to +150 °C operating junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - maximum continuous reverse voltage before significant conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - precise voltage at which avalanche conduction initiates; ensures consistent turn-on during transients |
| VC (Clamping Voltage) | 209 V at 209 A (10/1000 µs) - maximum voltage seen by protected circuit during worst-case surge; directly limits stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capability under standardized 10/1000 µs surge; validates suitability for IEC 61000-4-5 Level 4 compliance |
| IPPM (Peak Pulse Current) | 209 A - peak surge current the device safely clamps without failure; correlates with system-level lightning/surge immunity requirements |
| TJmax | +150 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments |

FAQ
What is the clamping voltage of SMBJ130CAHE3/5B at its rated peak pulse current?
The SMBJ130CAHE3/5B has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 209 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees the protected circuit will not experience voltages exceeding 209 V during such transient events - a key parameter for ensuring downstream IC survival in surge-prone applications.
Is SMBJ130CAHE3/5B suitable for automotive applications?
Yes, SMBJ130CAHE3/5B is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the 88392 datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and surge robustness - making SMBJ130CAHE3/5B appropriate for under-hood and body electronics where reliability under thermal and electrical stress is mandatory.
How does the bidirectional design of SMBJ130CAHE3/5B affect PCB layout?
The bidirectional nature of SMBJ130CAHE3/5B eliminates polarity marking - there is no cathode band or orientation requirement. This allows unrestricted placement on PCBs, simplifying automated assembly and reducing risk of misorientation-related failures. Engineers can route either terminal to the line being protected without functional impact, which is especially valuable in differential or floating signal paths.
What is the thermal resistance of SMBJ130CAHE3/5B, and how does it influence derating?
SMBJ130CAHE3/5B has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 100 °C/W. When mounted on the recommended 0.2" × 0.2" copper pads, these values enable full 600 W pulse power handling at TA = 25 °C. Derating curves in Figure 2 of the datasheet show usable pulse power drops to ~300 W at 75 °C ambient - critical for thermal design in enclosed enclosures.
Does SMBJ130CAHE3/5B meet RoHS and halogen-free requirements?
SMBJ130CAHE3/5B is RoHS-compliant (per EU Directive 2011/65/EU) and carries the "HE3" suffix indicating AEC-Q101 qualification and RoHS compliance. It is not halogen-free - that designation requires the "HM3" suffix (e.g., SMBJ130CAHM3/5B). The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin-plated per J-STD-002.
