Product details
Overview
SA130A from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode with 130V working stand-off voltage, 144–159V breakdown voltage at 1mA test current, and 209V maximum clamping voltage at 2.5A peak pulse current. It features low leakage (<1μA at 130V), fast response (<1.0ps), and DO-204AC (DO-15) package for automotive-grade surge protection in power supply rails.
For engineers reviewing the SA130A datasheet, SA130A pinout, SA130A application, or SA130A equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance under 10/1000μs transients, thermal derating behavior, and real-world ESD/inductive switching protection use cases - all confirmed from Taiwan Semiconductor's official SA Series L2105 specification.
Technical Context
The SA130A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 144–159V VBR range at 1mA. Its 209V VC clamping voltage at 2.5A IPPM ensures downstream ICs see limited overvoltage during 500W, 10/1000μs surges. Thermal design relies on junction-to-lead resistance and derating above 25°C per Fig.2.
It complies with ANSI/IEEE C62.35 for transient suppression and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements. Polarity is marked by cathode band; no internal series impedance or integrated filtering is present - it functions solely as a passive voltage-clamping device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before leakage rises significantly; sets upper limit for safe DC bias in protected line |
| VBR @ IT=1mA | 144–159 V - Breakdown threshold range; defines onset of clamping action under standardized test conditions |
| VC @ IPPM=2.5A | 209 V - Clamped voltage during 10/1000μs surge; determines worst-case overvoltage seen by downstream circuitry |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off; negligible power loss and signal interference in high-impedance circuits |
| PPK | 500 W - Peak pulse power handling per 10/1000μs waveform; defines single-event surge energy absorption capability |
| TJMAX | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with proper PCB thermal relief |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with 0.400g mass, UL 94V-0 molding, and tin-plated leads per J-STD-002 |
Pinout & Package
SA130A uses a two-terminal DO-204AC (DO-15) axial package. Cathode is marked by a band; anode is unmarked end. Leads are pure tin-plated and solderable per J-STD-002. Mechanical dimensions conform to JEDEC DO-15 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry / Surge return path | Connected to ground or low-impedance return node; completes clamping loop during transient events |
| Cathode (banded end) | Reverse-biased terminal / Protected line connection | Connected to the line being protected (e.g., 12V rail); conducts avalanche current when VLINE > VBR |

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 130V VWM, but lower PPK = 400W; VC = 214V @ 2.2A; SMA package (surface-mount) | Not suitable for 500W surge requirements; requires PCB rework for SMT vs. through-hole | Select only if board space constraints mandate SMT and surge energy is confirmed ≤400W |
| P6SMB130A | Identical VWM/VBR/VC specs and 500W rating, but in SMB package; slightly higher IR (5μA @ VWM) | Surface-mount alternative with same clamping performance; lacks AEC-Q101 qualification | Use where automotive qualification is not required and SMT assembly is preferred |
Compared with SMAJ130A and P6SMB130A, the SA130A offers verified AEC-Q101 qualification, through-hole DO-15 reliability for high-vibration environments, and guaranteed ≤1μA leakage - critical for low-power always-on automotive modules.

FAQ
What is the clamping voltage of SA130A under standard 10/1000μs surge conditions?
The SA130A has a maximum clamping voltage (VC) of 209 V at 2.5 A peak pulse current (IPPM) under the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the highest voltage imposed on the protected circuit during a 500W transient event. The SA130A datasheet confirms this parameter in Table 4 of Version L2105.
Is SA130A qualified for automotive applications?
Yes, SA130A is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of the official SA Series datasheet (Version L2105). This qualification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock - confirming suitability for under-hood and chassis-mounted automotive electronics. The "H" suffix variant (e.g., SA130AH) denotes AEC-Q101 compliance, and SA130A falls under that qualified family.
What is the maximum operating junction temperature for SA130A?
The SA130A has a maximum junction temperature (TJMAX) of +175°C, as specified in the "ABSOLUTE MAXIMUM RATINGS" table. This allows reliable operation in high-ambient environments such as automotive engine compartments or industrial enclosures, provided PCB thermal relief (e.g., copper pour, lead length) follows Taiwan Semiconductor's derating guidelines in Fig.2 of the SA Series datasheet.
Does SA130A have bidirectional capability?
No, SA130A is a unidirectional TVS diode. Its marking includes a cathode band, and its electrical characteristics (e.g., VF = 3.5 V at 35 A) apply only in forward conduction. For bidirectional protection, Taiwan Semiconductor specifies CA-suffixed parts (e.g., SA130CA); SA130A is strictly for suppressing positive-going transients on grounded systems.
What package type does SA130A use, and are its leads lead-free?
SA130A uses the DO-204AC (DO-15) axial package with pure tin-plated leads compliant with J-STD-002 solderability standards. The molding compound meets UL 94V-0 flammability rating, and the device is RoHS-compliant and halogen-free per IEC 61249-2-21 - confirming lead-free construction and environmental compliance.
