Product details
Overview
P0130AA from STMicroelectronics is a gate-sensitive silicon-controlled rectifier (SCR) in TO-92 package, rated for 100 V repetitive peak off-state voltage (VDRM/VRRM), 0.8 A RMS on-state current, and ultra-low 1 µA gate trigger current (IGT). It serves as the main switching element in electronic fluorescent lamp starters, working with TN22 A.S.D™ and a series resistor to initiate lamp ignition.
For engineers reviewing the P0130AA datasheet, P0130AA pinout, P0130AA application, or P0130AA equivalent, key selection criteria include its sub-microampere IGT sensitivity, 50 A/µs dI/dt rating at 125°C, 100 V blocking capability, and thermal resistance of 150 °C/W junction-to-ambient - critical for compact, thermally constrained starter designs.
Technical Context
The P0130AA is a unidirectional thyristor with asymmetric blocking capability (VDRM = VRRM = 100 V) and gate-triggered turn-on only. Its low 1 µA IGT enables direct drive from high-impedance timing circuits without external amplification.
It exhibits a latching current (IL) ≤ 6 mA and holding current (IH) ≤ 5 mA at 25°C, with dynamic on-state resistance (Rd) ≤ 600 mΩ and threshold voltage (Vt0) ≤ 0.95 V at 125°C - ensuring low conduction loss and stable turn-off behavior in AC line-frequency switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 100 V - supports operation on 120 VAC mains with margin against transients |
| IT(RMS) | 0.8 A - sustains continuous lamp preheat and run currents in starter circuits |
| IGT | 1 µA max - enables direct triggering from RC timing networks without buffer stages |
| dI/dt | 50 A/µs - prevents false turn-on during fast current transients in inductive ballast paths |
| Rth(j-a) | 150 °C/W - defines thermal derating in TO-92 plastic package under natural convection |
| VTM | 1.95 V max at 1.6 A - limits conduction power dissipation to <1.2 W at peak load |
| dV/dt | 25 V/µs min at 125°C - ensures immunity to line noise and switching spikes in lamp circuits |
Pinout & Package
Package: TO-92 plastic case (3-lead, through-hole), dimensions per ST mechanical drawing: E = 12.70 mm lead length, D = 4.40 mm body width, C = 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Connected to AC line phase; carries full lamp current during conduction |
| Cathode (K) | Main current exit terminal | Connected to lamp filament and return path; referenced for gate bias |
| Gate (G) | Trigger control input | Receives µA-level pulse to initiate conduction; high-impedance node sensitive to noise |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low gate trigger current | 1 µA max - eliminates need for gate driver transistors in cost-sensitive starters |
| High dI/dt immunity | 50 A/µs - prevents commutation failure when switching inductive ballast currents |
| Thermal robustness | 125°C max junction temperature - supports reliable operation inside enclosed lamp bases |
| Low on-state voltage drop | Vt0 ≤ 0.95 V at 125°C - reduces self-heating and improves efficiency in thermally limited TO-92 |
Applications
| Fluorescent Lamp Electronic Starter | AC Phase-Control Dimmer (Low-Power) |
|---|---|
Use Scenario: Initiates ionization in rapid-start fluorescent tubes by delivering timed current pulse to filaments before main arc strike. IC Role / Device Role / Timing Role: Main switching thyristor triggered by RC network and TN22 A.S.D™; provides zero-crossing synchronized turn-on. Use Value: Sub-µA IGT allows direct integration with passive timing components, reducing BOM count and board space by >30% vs. standard SCRs. | Use Scenario: Controls brightness of incandescent or resistive loads up to 100 W on 120 VAC lines using leading-edge phase-cut. IC Role / Device Role / Timing Role: Bidirectional switch (with external diode) enabling half-wave AC control; gate driven by DIAC or optocoupler. Use Value: 100 V VDRM and 0.8 A IT(RMS) support safe operation at 120 VAC with margin; TO-92 enables direct mounting on small PCBs. |
| AC Motor Soft-Start (Fan/Blower) | Overvoltage Crowbar Protection |
Use Scenario: Limits inrush current during startup of shaded-pole or PSC motors in HVAC blowers and exhaust fans. IC Role / Device Role / Timing Role: SCR placed in series with motor winding; triggered after delay to ramp voltage gradually. Use Value: 8 A non-repetitive surge rating (tp = 8.3 ms) handles motor locked-rotor current without failure. | Use Scenario: Protects downstream DC supplies from overvoltage events by shorting input rail to ground when threshold exceeded. IC Role / Device Role / Timing Role: Gate-triggered crowbar device; activated by voltage monitor IC or Zener clamp circuit. Use Value: 1 µA IGT enables precise trip point setting with high-value resistor dividers, minimizing standby current draw. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT169G | Higher IGT (50 µA typ), same VDRM (100 V), TO-92 package | Requires gate amplification in ultra-low-power timing circuits | Choose when higher noise immunity is needed and gate drive capability exists |
| TYN108 | Higher IT(RMS) (1 A), higher IGT (50 µA), TO-220 package | Not suitable for space-constrained starter PCBs due to larger footprint and thermal mass | Choose for higher-current AC switching where board area and heatsinking allow |
Compared with BT169G and TYN108, the P0130AA uniquely delivers µA-level gate sensitivity in TO-92, enabling minimalist starter designs without gate buffers - a critical advantage where component count, size, and standby power are tightly constrained.

FAQ
What is the maximum allowable gate-cathode resistance for reliable triggering?
The datasheet specifies that dV/dt immunity degrades significantly above 1 kΩ RGK, and IGT increases with temperature. For guaranteed turn-on across -40°C to +125°C, RGK must not exceed 1 kΩ. At 125°C, IGT rises to ~3 µA, so a 12 V source with 1 kΩ yields 12 mA - well above required trigger current.
Can P0130AA be used in 230 VAC applications?
No - its VDRM/VRRM is rated at 100 V, providing insufficient margin for 230 VAC peak voltage (≈325 V). Using it in such systems risks catastrophic failure due to off-state breakdown. For 230 VAC, select an SCR with ≥400 V VDRM, such as the BT136-600 or TIC226M.
How does junction temperature affect holding current (IH)?
IH increases with junction temperature: typical values rise from ~2 mA at 25°C to ~5 mA at 125°C. This means the device requires higher load current to remain latched at elevated temperatures. Designers must ensure minimum lamp or load current exceeds IH across the full operating temperature range.
Is P0130AA RoHS compliant and halogen-free?
Yes - per STMicroelectronics' official product change notification (PCN) #17-0022, all P0130AA devices manufactured after January 2017 are RoHS-compliant and halogen-free. The TO-92 package uses flame-retardant epoxy meeting UL94 V-0, and lead finish is matte tin.
