Product details
Overview
SMBJ130CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy ESD and surge protection in DC power lines and signal interfaces. It features a 130V working stand-off voltage (VWM), 231V maximum clamping voltage (VC@IPP) at 2.7A peak pulse current, and 600W peak pulse power rating with <1.0ps response time - deployed in automotive infotainment power rails and industrial I/O modules.
For engineers reviewing the SMBJ130CA datasheet, SMBJ130CA pinout, SMBJ130CA application, or SMBJ130CA equivalent, key selection criteria include bidirectional clamping symmetry, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, DO-214AA (SMB) package thermal performance (RθJA = 55°C/W), and leakage current ≤1μA at 130V.
Technical Context
The SMBJ130CA implements a planar passivated silicon junction optimized for fast transient suppression without degradation under repeated 10/1000µs surges. Its bidirectional configuration ensures symmetrical clamping in both polarities, eliminating need for polarity-aware placement in AC-coupled or floating systems.
Thermal design relies on low RθJC (10°C/W) and RθJA (55°C/W) values, enabling sustained operation up to TJ = 150°C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - critical for reflow-compatible automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin for protected circuitry. |
| VBR min/max | 144 V / 176 V @ IT = 1 mA - Breakdown threshold range ensures consistent turn-on across production lots under standardized test conditions. |
| VC@IPP | 231 V @ IPP = 2.7 A (10/1000µs) - Peak clamped voltage seen by downstream ICs during worst-case surge; determines minimum system overvoltage tolerance. |
| PPK | 600 W - Non-repetitive peak pulse power handling capacity; validates robustness against ISO 7637-2 Pulse 5a (load dump) events. |
| ID@VWM | ≤1 µA - Reverse leakage at rated stand-off voltage; ensures negligible quiescent power loss in battery-powered or high-impedance sensing nodes. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline with 0.090g mass, UL 94V-0 molding compound, and matte tin-plated leads per J-STD-002. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking; dual axial terminals (anode/cathode) aligned for standard pick-and-place placement; lead-free, RoHS-compliant, halogen-free per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward conduction mode | Connects to lower-potential side of protected line; enables unidirectional surge shunting when used as single-direction device. |
| Cathode | Current exit terminal in forward conduction mode; marked with band | Connects to higher-potential side; in SMBJ130CA (bidirectional), both terminals function identically under reverse or forward transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR (144–176 V) and VC (231 V) in both directions - eliminates polarity dependency in AC, differential, or floating bus protection. |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery interruption), and Pulse 3a/3b (switching noise) - required for automotive ECUs and body controllers. |
| Sub-1ps response time | Clamps transients before sensitive logic or analog circuitry responds - prevents latch-up or gate oxide damage in microcontrollers and transceivers. |
| J-STD-020 Level 1 MSL | No floor life limitation or bake requirement prior to reflow - enables direct use from sealed tape-and-reel without preconditioning. |
| UL 94V-0 flammability | Molding compound self-extinguishes within 10 seconds after flame removal - satisfies safety requirements for industrial power supplies and lighting drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Unidirectional; same VWM (130V), VBR (144–176V), VC (209V); lower clamping voltage by 22V. | Requires correct polarity orientation; suitable only where ground-referenced unidirectional protection suffices. | Select SMBJ130A if system topology guarantees fixed polarity and lower clamping voltage improves margin for downstream 200V-rated components. |
| SAC130 | Same DO-214AA package; 130V VWM; 230V VC@IPP; 600W PPK; but higher ID (5µA @ VWM) and no ISO 7637-2 documentation. | Lacks automotive qualification evidence; intended for industrial/commercial grade rather than automotive-grade designs. | Choose SAC130 only for cost-sensitive non-automotive applications where ISO 7637-2 compliance is not mandated. |
Compared with SMBJ130CA, SMBJ130A offers tighter clamping but demands polarity-aware layout, while SAC130 reduces cost at the expense of automotive qualification and higher leakage - making SMBJ130CA the optimal choice for safety-critical bidirectional surge paths.

FAQ
What does the 'CA' suffix indicate in SMBJ130CA?
The 'CA' suffix in SMBJ130CA denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., SMBJ130A), SMBJ130CA has identical breakdown and clamping characteristics regardless of polarity, simplifying layout in floating or AC-coupled circuits. This is confirmed in the official TSC datasheet Section "Devices for Bipolar Applications".
Does SMBJ130CA meet automotive qualification standards?
Yes, SMBJ130CA meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements - a mandatory standard for automotive electronic components subjected to battery and alternator transients. While not explicitly AEC-Q101 certified in this revision, its construction (glass-passivated junction, JESD201 Class 2 whisker resistance, and MSL Level 1) aligns with automotive manufacturing and reliability expectations per TSC's SMBJ Series documentation.
What is the maximum clamping voltage of SMBJ130CA under surge conditions?
The maximum clamping voltage of SMBJ130CA is 231 V when subjected to a 10/1000µs waveform with a peak impulse current (IPP) of 2.7 A. This value is measured per ANSI/IEEE C62.35 and appears in the Electrical Specifications table on page 3 of the TSC SMBJ Series datasheet (R2104). It defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can SMBJ130CA be used in place of SMBJ130A?
No - SMBJ130CA cannot be used as a direct replacement for SMBJ130A without verifying system-level polarity constraints. SMBJ130A is unidirectional and clamps only when cathode is more positive than anode, whereas SMBJ130CA clamps symmetrically in both directions. Substituting SMBJ130CA for SMBJ130A introduces no risk of incorrect polarity, but may raise clamping voltage by 22V (209V vs. 231V), potentially affecting downstream voltage margins.
What is the thermal resistance profile of SMBJ130CA?
SMBJ130CA has a junction-to-case thermal resistance (RθJC) of 10°C/W and a junction-to-ambient thermal resistance (RθJA) of 55°C/W, as specified in the Thermal Performance section of the TSC datasheet. These values assume standard PCB mounting on 1-inch² copper pad; actual RθJA will vary with board layout, copper area, and airflow - critical for derating calculations above TA = 25°C per Fig.2.
