Product details
Overview
SMBJ130H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection in automotive and industrial power rails. It features a 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR), 231V maximum clamping voltage (VC) at 2.7A peak impulse current (IPP), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBJ130H datasheet, SMBJ130H pinout, SMBJ130H application, or SMBJ130H equivalent, key selection considerations include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b transients, junction-to-ambient thermal resistance (55°C/W), unidirectional polarity marking, and compatibility with automated SMT placement on 150°C-rated PCBs.
Technical Context
The SMBJ130H operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-1ps response time and low leakage (<1μA at 130V). Its 600W peak pulse power rating (10/1000µs waveform) and 150°C maximum junction temperature support robust protection in 12V/24V/48V vehicle electrical systems.
Thermal design is enabled by RθJC = 10°C/W and RθJA = 55°C/W, while its DO-214AA package meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements. Polarity is indicated by a cathode band, and it complies with RoHS and halogen-free standards per IEC 61249-2-21.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130A | Same DO-214AC (SMA) package; 231V VC @ 2.7A but rated for 400W PPK (10/1000µs) | Lower power handling limits use in high-energy load dump scenarios | Select SMBJ130H when 600W surge immunity per ISO 7637-2 Pulse 5a is required |
| ON Semiconductor 1.5SMC130A | DO-214AB (SMC) package; 231V VC @ 2.7A, 600W rating, but higher RθJA = 60°C/W | Less efficient thermal dissipation in compact layouts | Prefer SMBJ130H for space-constrained automotive modules needing lower thermal resistance |

FAQ
What is the maximum clamping voltage of the SMBJ130H under standard test conditions?
The SMBJ130H has a maximum clamping voltage (VC) of 231 V when subjected to a 10/1000 µs surge waveform at 2.7 A peak impulse current (IPP), as specified in the Taiwan Semiconductor datasheet revision A2102. This value defines the upper voltage limit imposed on protected circuitry during transient events and is measured at TA = 25°C with defined test conditions per ANSI/IEEE C62.35.
Is the SMBJ130H suitable for bidirectional transient protection?
No, the SMBJ130H is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking. For bidirectional operation, Taiwan Semiconductor specifies the SMBJ130CH or SMBJ130CAH variants, which exhibit symmetrical breakdown behavior in both polarities and are tested accordingly per the datasheet's bipolar electrical specifications.
Does the SMBJ130H meet automotive qualification standards?
Yes, the SMBJ130H is explicitly AEC-Q101 qualified, as stated in the product features section of the Taiwan Semiconductor datasheet. It also meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements for electrical disturbances in road vehicles, confirming its suitability for use in automotive ECUs, body control modules, and infotainment power supplies.
What is the thermal resistance profile of the SMBJ130H?
The SMBJ130H has a junction-to-case thermal resistance (RθJC) of 10°C/W and a junction-to-ambient thermal resistance (RθJA) of 55°C/W, measured under standard JEDEC test conditions. These values enable effective heat dissipation in surface-mount layouts with adequate copper pour and are critical for sustaining repeated surge events without exceeding the 150°C maximum junction temperature.
How does the SMBJ130H compare to the SMBJ130AH variant?
The SMBJ130AH differs from the SMBJ130H in tighter breakdown voltage tolerance (144–159 V vs. 144–176 V), lower clamping voltage (209 V vs. 231 V at 3.0 A), and slightly higher leakage current specification. Both share identical package, power rating, and AEC-Q101 qualification-but the SMBJ130H offers broader VBR range and higher surge current margin, making it more tolerant of manufacturing variation in high-energy applications.
