Product details
Overview
1.5SMC130CAH from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power lines. It delivers 1500W peak pulse power, 124V–137V breakdown voltage (VBR), 111V working stand-off voltage (VWM), and clamps transients to ≤179V at 8.7A peak impulse current - deployed in CAN bus interfaces and 24V DC power rails.
For engineers reviewing the 1.5SMC130CAH datasheet, 1.5SMC130CAH pinout, 1.5SMC130CAH application, or 1.5SMC130CAH equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, and DO-214AB (SMC) package thermal performance (RθJA = 50°C/W).
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast transient suppression in bidirectional signal and power lines. Its symmetrical I-V characteristics enable identical clamping behavior in both polarities, supporting robust ESD and load-dump protection without polarity sensitivity.
It meets automotive-grade reliability requirements including AEC-Q101 stress testing and moisture sensitivity level 1 (per J-STD-020). Thermal design is enabled by low RθJC = 15°C/W and UL 94V-0 molding compound - critical for sustained operation up to TJ = +150°C in engine control units and industrial PLCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - ensures reliable triggering above 111 V system operating voltage while avoiding false trips |
| VWM | 111 V - maximum continuous reverse voltage before leakage exceeds 1 µA, suitable for 24V/48V industrial bus systems |
| VC@IPPM | ≤179 V at 8.7 A - limits downstream voltage stress during ISO 7637-2 Pulse 5a (load dump) events |
| PPK | 1500 W - handles high-energy transients such as lightning-induced surges on long cable runs |
| RθJA | 50 °C/W - enables PCB-level thermal management without heatsinks in standard SMC footprint layouts |
| Response time | <1.0 ps - suppresses ESD events (IEC 61000-4-2) before sensitive interface ICs are damaged |
| Leakage @ VWM | <1 µA - minimizes standby power loss in always-on automotive modules |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, bidirectional configuration with cathode band omitted (symmetrical terminals).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (reversible) | Bidirectional surge path | Either terminal serves as anode or cathode depending on transient polarity - no orientation required during placement |
| Case | Thermal conduction path | Exposed metal slug provides primary heat dissipation to PCB copper; requires thermal pad per JEDEC MO-214AC |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, HTRB, and mechanical shock per Rev G |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (capacitive coupling) waveforms |
| Glass passivated junction | Eliminates wire bond failure modes and improves humidity resistance vs. epoxy-passivated alternatives |
| Moisture sensitivity level 1 | Zero bake requirement prior to reflow - supports standard SMT assembly without dry-pack handling |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU for green electronics manufacturing |
Applications
| Automotive Power Distribution | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protection of 24V battery-fed ECUs against load dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontrollers. Use Value: Limits clamped voltage to 179 V, preventing damage to 36V-rated input stages while sustaining 1500W surge energy. |
Use Scenario: Shielding CAN transceivers (e.g., TJA1042) from ESD and coupled noise on vehicle wiring harnesses. IC Role / Device Role: Bidirectional line protector on CAN_H/CAN_L differential pair. Use Value: Sub-1ps response captures fast ESD events; symmetrical clamping maintains common-mode integrity without bias disruption. |
| Telecom DC Power Input | Factory Automation I/O Module |
Use Scenario: Surge protection on -48V telecom rectifier outputs exposed to lightning-induced surges on outdoor plant cabling. IC Role / Device Role: Secondary-stage TVS after gas discharge tube (GDT) front-end filtering. Use Value: 1500W rating handles residual energy passed through GDT; 111V VWM avoids conduction during normal -48V ±10% operation. |
Use Scenario: Protecting 24V digital input channels in PLC modules from field-wiring transients and relay coil kickback. IC Role / Device Role: Point-of-entry clamp on each isolated input channel before optocoupler or Schmitt trigger. Use Value: Low 1µA leakage preserves high-impedance sensing; DO-214AB footprint allows dense channel spacing without thermal crosstalk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPK = 600W; same VBR range but SMB package (smaller thermal mass) | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 3); unsuitable for ISO 7637-2 Pulse 5a | Select when board space is constrained and surge energy is ≤600W |
| 1.5KE130CA | Through-hole TO-204AA (DO-41); higher RθJA ≈ 65°C/W; same electrical specs | Requires manual or wave soldering; incompatible with automated SMT lines | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAH uniquely balances 1500W surge capacity, SMT manufacturability, and AEC-Q101 qualification - making it the preferred choice for production automotive and industrial modules requiring zero rework risk and validated reliability.

FAQ
What is the clamping voltage of the 1.5SMC130CAH under maximum rated surge current?
The 1.5SMC130CAH clamps to a maximum of 179 V when subjected to its rated peak impulse current of 8.7 A (IPPM), as specified in the Electrical Specifications table under "Maximum clamping voltage VC@IPPM". This value is measured using the 10/1000 μs waveform defined in Fig.5 and ensures downstream circuitry remains within safe voltage limits during standardized surge events like ISO 7637-2 Pulse 5a.
Is the 1.5SMC130CAH suitable for bidirectional signal lines such as RS-485 or CAN?
Yes, the 1.5SMC130CAH is explicitly designed for bidirectional use, as indicated by the "CAH" suffix and confirmed in the datasheet's "Devices for Bipolar Applications" section. Its symmetrical breakdown characteristics ensure identical clamping behavior on both polarities - making it ideal for protecting differential buses like CAN_H/CAN_L or RS-485 A/B lines without requiring polarity-aware layout or additional components.
Does the 1.5SMC130CAH require special PCB layout considerations for thermal management?
Yes - the 1.5SMC130CAH uses a DO-214AB (SMC) package with an exposed metal slug that serves as the primary thermal path. To achieve the specified RθJA = 50°C/W, the PCB must include a minimum 100 mm² copper thermal pad connected via ≥4 thermal vias (0.3 mm diameter) to internal ground planes. Insufficient copper area or missing vias will degrade power handling and accelerate parametric drift at elevated ambient temperatures.
How does the 1.5SMC130CAH differ from the unidirectional 1.5SMC130CH variant?
The 1.5SMC130CAH is bidirectional with symmetrical VBR (124–137 V) in both directions, while the 1.5SMC130CH is unidirectional and features a cathode band marking. The CAH version has no polarity marking and supports AC-coupled or floating-line protection; the CH version must be oriented correctly and offers slightly lower VF (3.5 V @ 50 A) in forward conduction - relevant only for DC power rail applications with reverse-battery protection.
What standards does the 1.5SMC130CAH meet for automotive electromagnetic compatibility?
The 1.5SMC130CAH meets ISO 7637-2 for automotive transient immunity (Pulse 1, 2a, 2b, 3a, 3b) and is AEC-Q101 qualified for stress testing including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock. It also complies with JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity level 1 - confirming suitability for lead-free reflow assembly in automotive production environments.
