Product details
Overview
SA130CAH from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, designed for automotive and industrial overvoltage protection. It features 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR) at 1mA test current, 2.2A peak pulse current (IPPM), 230V clamping voltage (VC) at IPPM, and 500W peak pulse power rating at 10/1000μs waveform.
For engineers reviewing the SA130CAH datasheet, SA130CAH pinout, SA130CAH application, or SA130CAH equivalent, key selection considerations include its AEC-Q101 qualification, unidirectional polarity, DO-15 mechanical compatibility, low leakage (<1μA @ VWM), and fast response time (<1.0ps from 0V to VBR), critical for protecting automotive ECUs, power supply rails, and CAN/LIN bus interfaces against ESD and load dump transients.
Technical Context
The SA130CAH operates as a unidirectional avalanche diode with precise breakdown behavior defined at IT = 1mA, delivering stable clamping under repetitive and non-repetitive surge conditions per IEC 61000-4-2/4-4/4-5. Its junction temperature range spans –55°C to +175°C, supporting under-hood automotive deployment.
It exhibits a maximum temperature coefficient of VBR at 175 mV/°C, enabling predictable voltage drift across thermal extremes. The device uses pure tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing, ensuring long-term solder joint reliability in high-vibration environments.
Key Specifications

Pinout & Package
SA130CAH is a two-terminal unidirectional TVS diode in DO-204AC (DO-15) package. Cathode is marked by a band on the body; anode is unmarked. Leads are pure tin-plated, 9.5mm length, suitable for through-hole mounting on FR-4 PCBs with 10×10 mm copper pads per terminal per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side return path | Provides low-impedance path for surge current to ground when cathode is held at higher potential; must be routed with minimal inductance. |
| Cathode | Marked terminal; connected to protected line (e.g., battery rail, signal line) | Defines clamping reference; voltage at this node is limited to VC during transients; polarity marking prevents incorrect installation in unidirectional protection schemes. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias HAST, and mechanical shock-enables use in engine control units and ADAS modules without additional qualification. |
| 500W surge rating (10/1000μs) | Withstands ISO 7637-2 Load Dump Pulse 5a (up to 110V, 400ms) and Pulse 1 (inductive switch-off) without degradation when properly heatsinked. |
| Clamping voltage ≤230V | Ensures protected ICs (e.g., SBCs, CAN transceivers) experience no more than 230V transient stress, staying within absolute maximum ratings of 36V–40V-rated devices via appropriate series impedance. |
| Response time <1.0ps | Activates faster than ESD events (IEC 61000-4-2, 15kV contact), preventing latch-up or gate oxide damage in sensitive CMOS inputs before protection can engage. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; supports green manufacturing and end-of-life recycling requirements for Tier 1 automotive suppliers. |
Applications
| Automotive Power Rail Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 12V/24V battery-fed microcontroller power supplies in engine control units (ECUs) against load dump and jump-start surges. IC Role / Device Role: Unidirectional TVS placed between VBAT and GND, upstream of LDO or DC-DC converter input. Use Value: Limits transient voltage to ≤230V, preventing brownout, reset, or permanent damage to 5V/3.3V regulators and MCU cores during ISO 7637-2 Pulse 5a events. | Use Scenario: Safeguarding high-speed CAN FD transceivers (e.g., TJA1044, SN65HVD230) from ESD and electrical fast transients on CAN_H/CAN_L lines. IC Role / Device Role: Bidirectional TVS not applicable here; SA130CAH used only on VCC rail or shield ground-its unidirectional nature suits power-supply-side clamping, not differential data lines. Use Value: Maintains system-level EMC immunity (IEC 61000-4-4/4-5) while adding <1μA leakage, avoiding signal integrity impact on 5 Mbps CAN FD buses. |
| Industrial PLC Input Protection | LED Driver Overvoltage Clamp |
Use Scenario: Shielding 24V digital input channels in programmable logic controllers from inductive kickback caused by relay or solenoid switching. IC Role / Device Role: Connected between input terminal and common rail, absorbing energy from L·di/dt spikes up to 500W. Use Value: Enables robust operation in factory automation environments where >1000 switching cycles/day occur, extending input optocoupler lifetime and reducing field failures. | Use Scenario: Preventing catastrophic failure of constant-current LED drivers (e.g., AL8863, LM3409) due to open-circuit or overvoltage faults in automotive lighting modules. IC Role / Device Role: Placed across driver output terminals to clamp flyback voltage during LED string disconnection or thermal shutdown. Use Value: Limits output voltage excursion to 230V, protecting external MOSFETs and internal gate drivers from avalanche breakdown during fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A | Same VWM (130V), same DO-214AC package; lower PPK (400W), higher VC (250V), no AEC-Q101 qualification | Not approved for automotive under-hood use; suitable for industrial/commercial power supplies only | Select SMAJ130A only if AEC-Q101 compliance is unnecessary and layout space allows SMA footprint change. |
| P6SMB130A | Same VWM (130V), same DO-214AA package; identical PPK (600W), slightly lower VC (220V); AEC-Q101 available but not standard | Requires requalification for automotive use; different thermal resistance due to larger package mass (0.48g vs. 0.40g) | Choose P6SMB130A only when higher surge margin is needed and board real estate permits larger SMB outline. |
Compared with SMAJ130A and P6SMB130A, SA130CAH delivers guaranteed AEC-Q101 qualification, tighter VBR tolerance (144–176V vs. ±5%), and DO-15 compatibility with legacy through-hole designs-making it the preferred choice for drop-in replacement in existing automotive harnesses and ECUs.

FAQ
What is the polarity configuration of SA130CAH?
SA130CAH is a unidirectional TVS diode with cathode indicated by a band on the DO-204AC (DO-15) package body. When installed correctly-with cathode toward the protected line and anode to ground-it clamps positive transients only. Reverse connection renders it ineffective for overvoltage protection and may cause failure during surge events. Always verify orientation using the marking diagram in TSC's SA Series datasheet revision L2105.
Does SA130CAH meet AEC-Q101 requirements?
Yes, SA130CAH is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in TSC's SA Series specification sheet (Version L2105). It has passed stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST), making it suitable for automotive powertrain and chassis applications where reliability is mission-critical.
What is the maximum clamping voltage of SA130CAH under surge conditions?
The maximum clamping voltage (VC) of SA130CAH is 230 V at 2.2 A peak pulse current (IPPM), measured under the standard 10/1000μs double-exponential waveform. This value represents the upper limit of voltage seen by downstream components during worst-case surge events and is critical for ensuring protected ICs remain within their absolute maximum voltage ratings.
Can SA130CAH be used for bidirectional transient protection?
No, SA130CAH is strictly unidirectional and unsuitable for bidirectional applications such as differential data lines (e.g., CAN, RS-485). For bidirectional protection, TSC offers the SA130A variant (with "A" suffix), which provides symmetrical clamping in both polarities. Using SA130CAH in reverse-biased configurations risks permanent breakdown and failure due to lack of reverse avalanche capability.
What is the thermal derating behavior of SA130CAH above 25°C ambient?
SA130CAH's peak pulse power (PPK) derates linearly above TA = 25°C, following the curve in Figure 2 of the SA Series datasheet (L2105). At 75°C ambient, PPK drops to approximately 350W; at 125°C, it falls to ~175W. This derating must be applied when calculating surge margin in high-temperature environments like engine compartments, where junction temperature rise depends on PCB copper area and airflow.
