Product details
Overview
SA130A from Fairchild Semiconductor is a unidirectional 500 W transient voltage suppressor (TVS) diode in DO-15 package, featuring a 130 V reverse stand-off voltage (VRWM), 144–159 V breakdown voltage (VBR), and 209 V clamping voltage (VC) at 23.2 A peak pulse current (IPPM) on 10/1000 μs waveform - used for primary overvoltage protection in DC power rails and industrial I/O interfaces.
For engineers reviewing the SA130A datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DO-15 terminal mapping, clamping performance under surge conditions, and validated alternatives for industrial-grade surge suppression design.
Technical Context
The SA130A operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast transient response (<1.0 ps rise time from 0 V to VBR) and low incremental surge resistance to maintain stable clamping during high-energy ESD or lightning-induced surges. Its 175 °C maximum junction temperature supports operation in harsh thermal environments.
Designed for single-pulse 10/1000 μs waveform compliance per R.E.A. standards, it delivers 500 W peak pulse power with 1.0 μA reverse leakage at VRWM and exhibits steady-state power dissipation of 1.0 W at 75 °C ambient with 0.375" lead length - enabling reliable integration into board-level protection circuits without active thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 500 W - sustains single high-energy transients without failure in telecom or industrial power input stages |
| Reverse Stand-off Voltage (VRWM) | 130 V - defines maximum continuous operating voltage before clamping begins |
| Breakdown Voltage (VBR) | 144–159 V @ 1.0 mA - ensures predictable avalanche initiation across production lot |
| Clamping Voltage (VC) | 209 V @ 23.2 A - limits downstream circuit voltage during surge to safe level |
| Peak Pulse Current (IPPM) | 23.2 A - quantifies maximum surge current the device can safely divert |
| Reverse Leakage (IR) | ≤1.0 μA @ 130 V - minimizes standby power loss in high-impedance sensing or battery-backed systems |
| Junction Temperature (TJ) | +175 °C - enables use in engine control units, motor drives, and outdoor power supplies |
Pinout & Package
SA130A uses the industry-standard DO-15 axial-leaded package with cathode indicated by a color band. The device has two terminals: anode and cathode - configured for unidirectional clamping from cathode to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path / reference node | Connected to system ground or low-side rail; completes clamping loop during overvoltage event |
| Cathode | Protected line connection | Connected to line under protection (e.g., +12 V rail); conducts when voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability and stable VBR across humidity and thermal cycling in industrial deployments |
| Fast response time | <1.0 ps from 0 V to VBR - intercepts fast-rising transients before sensitive ICs experience overstress |
| Low incremental surge resistance | Minimizes VC overshoot during high di/dt events, improving clamping precision |
| 500 W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 Ω source impedance) without derating |
| DO-15 mechanical compatibility | Enables drop-in replacement in legacy designs using standard axial through-hole footprint |
Applications
| Industrial PLC I/O Protection | DC Power Input Stage |
|---|---|
Use Scenario: Protecting 24 V digital input modules against induced surges from relay coil switching or field wiring faults. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input line and ground to clamp positive transients above 130 V. Use Value: Prevents latch-up or damage to optocouplers and microcontroller GPIOs while maintaining <1.0 μA leakage at nominal 24 V operation. |
Use Scenario: Safeguarding 110–130 V DC power inputs in railway signaling equipment exposed to traction return currents. IC Role / Device Role / Timing Role: Primary surge limiter on main DC bus prior to DC/DC converter input stage. Use Value: Clamps 209 V at 23.2 A to keep downstream converter within absolute max ratings during 500 W surge events. |
| Motor Drive Control Board | Telecom Line Card |
Use Scenario: Suppressing commutation spikes on gate drive supply rails feeding IGBT half-bridges. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp on isolated 15 V gate bias rail referenced to emitter. Use Value: Responds in <1.0 ps to limit transient overshoot to ≤209 V, preserving gate oxide integrity of high-voltage IGBTs. |
Use Scenario: Protecting Ethernet PHY interface power pins (e.g., +3.3 V, +5 V) from ESD and lightning-induced surges on building entry points. IC Role / Device Role / Timing Role: Secondary-level TVS on DC bias lines where primary gas discharge tube handles bulk energy. Use Value: Provides low-leakage (≤1.0 μA), precise clamping at 130 V VRWM to avoid false triggering while ensuring sub-210 V clamping ceiling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A (Bourns) | DO-214AA package; 130 V VRWM, 219 V VC @ 22.8 A; 600 W rating | Surface-mount layout; higher peak power but larger footprint than DO-15 | Select when SMT assembly and higher surge margin are prioritized over axial through-hole compatibility |
| P6SMB130A (Littelfuse) | DO-214AA package; identical VRWM and VBR range; 219 V VC @ 22.8 A; 600 W rating | Requires PCB redesign for SMD placement; same thermal profile limitations as SMBJ130A | Prefer when Littelfuse qualification or dual-sourcing requirements mandate alternate vendor part |
Compared with SA130A, SMBJ130A and P6SMB130A offer higher peak power (600 W) and surface-mount form factor but require layout changes and lack axial lead flexibility for field-repairable or high-vibration installations where DO-15 mechanical retention is critical.

FAQ
What is the clamping voltage of SA130A at its rated peak pulse current?
The SA130A has a maximum clamping voltage (VC) of 209 V at 23.2 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per R.E.A. definition and guarantees that downstream circuitry will not be exposed to voltages exceeding 209 V during a full-rated 500 W transient event. The SA130A maintains this clamping performance across its specified operating temperature range up to +175 °C junction temperature.
Is SA130A bidirectional or unidirectional?
SA130A is a unidirectional transient voltage suppressor, indicated by the absence of the "C" suffix (which denotes bidirectional variants like SA130CA). It conducts only when the cathode is driven positive relative to the anode - making it suitable for protecting positive DC rails where reverse polarity events are not expected. Its DO-15 package includes a visible cathode band for correct orientation during PCB assembly.
What is the maximum junction temperature rating for SA130A?
The SA130A is rated for a maximum operating junction temperature (TJ) of +175 °C, as confirmed in Fairchild's official datasheet Rev. D. This high-temperature capability allows deployment in thermally demanding environments such as motor drive enclosures, railway power converters, and outdoor telecom cabinets without derating under normal convection cooling conditions.
Does SA130A meet IEC 61000-4-5 surge immunity requirements?
Yes - the SA130A's 500 W peak pulse power rating on the 10/1000 μs waveform aligns with IEC 61000-4-5 Level 4 test criteria (4 kV line-to-line, 2 Ω source impedance), provided it is used with appropriate series impedance and layout practices. Its 209 V clamping voltage ensures protected circuits remain within safe operating limits during standardized surge testing.
What is the reverse leakage current specification for SA130A at rated VRWM?
The SA130A specifies a maximum reverse leakage current (IR) of 1.0 μA at its rated reverse stand-off voltage (VRWM) of 130 V and TA = 25 °C. This low leakage preserves efficiency in high-impedance monitoring circuits and avoids unintended loading on precision voltage rails - a key requirement in programmable logic controller (PLC) analog input modules and sensor front-ends.
