Product details
Overview
P0102DN 5AA4 from STMicroelectronics is a sensitive 0.8 A RMS SCR thyristor in SOT-223 package, rated for 600 V repetitive peak off-state voltage (VDRM/VRRM), 0.2 mA maximum gate trigger current (IGT), and 125 °C maximum junction temperature. It serves as a low-power gate driver for larger thyristors and overvoltage crowbar protection in standby-mode power supplies.
For engineers reviewing the P0102DN 5AA4 datasheet, P0102DN 5AA4 pinout, P0102DN 5AA4 application, or P0102DN 5AA4 equivalent, key selection criteria include gate sensitivity (≤200 µA), dV/dt immunity (≥75 V/µs at Tj = 125 °C), thermal resistance (Rth(j-t) = 30 °C/W), and ECOPACK®2-compliant SMT packaging for automated assembly.
Technical Context
This SCR operates with highly sensitive gate triggering (IGT ≤ 200 µA at 12 V, 140 Ω load), enabling reliable turn-on even with microcontroller-level drive capability. Its 600 V blocking rating and 75 V/µs dV/dt immunity at 125 °C support robust operation in noisy AC line protection circuits.
The device features a low on-state voltage (VTM ≤ 1.95 V at 1.6 A, 25 °C) and dynamic resistance (RD ≤ 600 mΩ at 125 °C), minimizing conduction losses in crowbar and fault-interrupting applications. Thermal design is supported by a 30 °C/W junction-to-tab resistance and validated SOT-223 footprint for FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 0.8 A - continuous RMS current handling capacity under 180° conduction angle at 70 °C ambient |
| VDRM / VRRM | 600 V - maximum repetitive off-state blocking voltage, suitable for 230 VAC mains-connected protection |
| IGT (max) | 200 µA - ultra-low gate trigger current enables direct drive from low-power logic or optocouplers |
| dV/dt (min) | 75 V/µs - high static dv/dt immunity ensures noise-immune operation without false triggering |
| Rth(j-t) | 30 °C/W - junction-to-tab thermal resistance supports heatsink mounting for sustained power dissipation |
| Tj (max) | 125 °C - maximum operating junction temperature, validated for industrial-grade reliability |

Applications
| Proximity Sensors | Ground Fault Circuit Interrupters |
|---|---|
Use Scenario: Detects metallic object presence via induced eddy-current disturbance in oscillator circuit. IC Role / Device Role / Timing Role: SCR acts as zero-crossing-triggered latch to activate alarm or disable power upon detection. Use Value: Low IGT allows direct interface with low-output comparator outputs; 600 V rating isolates sensor front-end from mains-referenced loads. | Use Scenario: Monitors differential current between live and neutral lines; triggers trip when imbalance exceeds threshold. IC Role / Device Role / Timing Role: SCR functions as crowbar element across AC line to force upstream breaker opening during fault. Use Value: 75 V/µs dV/dt immunity prevents nuisance tripping from switching transients; 125 °C Tj rating supports sealed enclosure operation. |
| Standby Mode Power Supplies | Arc Fault Circuit Interrupters |
Use Scenario: Maintains auxiliary power rail in low-load state while enabling rapid wake-up via controlled AC line switching. IC Role / Device Role / Timing Role: SCR provides isolated, low-leakage AC switch to energize standby transformer only when required. Use Value: IDRM ≤ 10 µA at 25 °C and ≤100 µA at 125 °C minimizes quiescent loss; SOT-223 enables compact layout near transformer. | Use Scenario: Detects high-frequency current signatures indicative of series arcing in branch circuits. IC Role / Device Role / Timing Role: SCR serves as fast-acting shunt crowbar to collapse line voltage and extinguish arc within half-cycle. Use Value: 8 A non-repetitive surge rating (tp = 8.3 ms) handles arc energy discharge; 600 V VDRM withstands post-arc recovery voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR gate-driving and crowbar protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP0102DN | Same die, TO-220 package; Rth(j-a) = 50 °C/W vs. 60 °C/W for SOT-223; higher I²t (0.32 A²s) | Better thermal performance in discrete heatsinked designs; not SMT-compatible | Select for higher surge endurance where board space permits through-hole mounting |
| Littelfuse S4006L | 600 V VDRM, but IGT = 5 mA (25× higher); TO-92 package; lower dV/dt (50 V/µs) | Requires stronger gate drive; unsuitable for microcontroller-direct use or high-noise environments | Select only when gate drive capability exceeds 5 mA and noise immunity is less critical |
Compared with STP0102DN and S4006L, P0102DN 5AA4 uniquely balances ultra-low gate sensitivity, SMT manufacturability, and validated 75 V/µs dV/dt immunity-making it optimal for space-constrained, noise-sensitive crowbar and sensing applications.

FAQ
What is the maximum allowable gate-cathode resistance for reliable triggering?
The datasheet specifies IGT testing with RGK = 1 kΩ. For guaranteed turn-on across temperature and process variation, RGK must not exceed 1 kΩ. At 125 °C, IGT rises to ~300 µA; using RGK > 1 kΩ risks failure to latch under worst-case conditions.
Can P0102DN 5AA4 be used in DC crowbar applications?
Yes - its 600 V VDRM/VRRM and 8 A non-repetitive surge rating support DC bus protection. However, ensure external snubber or clamping limits dV/dt during turn-off, as DC circuits lack natural current zero-crossings for commutation.
Is the SOT-223 tab electrically isolated from the package leads?
No - the metal tab is internally connected to the Anode (A) terminal. When mounted to a heatsink or copper pour, that surface becomes part of the anode circuit and must be insulated from other potentials unless intentionally tied to anode potential.
What is the minimum holding current (IH) at 125 °C?
IH is specified as ≤5 mA at 25 °C with RGK = 1 kΩ. While not explicitly tested at 125 °C, typical curves (Figure 6) show IH decreases ~30% at 125 °C, implying ≤3.5 mA. Design margin should assume ≤3 mA for worst-case latching retention.
