Product details
Overview
3P4MH(DY)-AZ from Renesas Electronics is a 3 A average on-state current, 400 V repetitive peak off-state voltage silicon-controlled rectifier (SCR) in TO-202AA package. It features 1.6 V typical on-state voltage at 10 A, 0.2 mA gate trigger current, and 80 µs commutating turn-off time. Used in noncontact switching for consumer electronics power control circuits.
For engineers reviewing the 3P4MH(DY)-AZ datasheet, 3P4MH(DY)-AZ pinout, 3P4MH(DY)-AZ application, or 3P4MH(DY)-AZ equivalent, key selection criteria include repetitive peak off-state voltage (VDRM = 400 V), critical dV/dt immunity (3 V/µs), junction-to-case thermal resistance (8 °C/W), and gate trigger sensitivity (VGT ≤ 0.8 V).
Technical Context
This P-gate fully diffused mold SCR operates as a latching unidirectional switch triggered by gate current. Its design supports half-wave AC phase control with single-cycle surge capability up to 65 A at 50 Hz and fusing ∫i²t rating of 20 A²s over 1–10 ms.
It requires external gate resistor (RGK = 1 kΩ specified) for reliable triggering and exhibits stable holding current (IH = 1–5 mA) across −40°C to +125°C junction temperature range. The device is not radiation-hardened and is rated for Standard quality grade applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 400 V - Maximum repetitive off-state voltage before conduction; defines AC line voltage handling limit in phase-control dimmers. |
| IT(AV) | 3 A at Tc = 87°C - Average forward current under specified heatsink conditions; determines continuous load capacity. |
| VTM | ≤1.6 V at IT = 10 A - On-state voltage drop; directly impacts conduction loss and thermal design in 50/60 Hz mains applications. |
| IGT / VGT | ≤0.2 mA / ≤0.8 V - Gate trigger threshold; enables low-power microcontroller-compatible drive without external amplification. |
| Tq | ≤80 µs - Commutating turn-off time; sets minimum dead-time requirement in forced-commutated AC controllers. |
| Rth(j-c) | 8 °C/W - Junction-to-case thermal resistance; used with heatsink data to calculate maximum allowable case temperature. |
| dV/dt | 3 V/µs - Critical rate-of-rise of off-state voltage; determines snubber requirements for inductive load switching. |
Pinout & Package
Package: TO-202AA (standard 3-lead molded plastic package, 1.4 g weight, UL94V-0 flame-retardant epoxy). Mounting surface compatible with jig-based lead forming and heatsink tablet attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| <1> Cathode | Current exit path during conduction | Connected to load return; must be thermally coupled to heatsink via case contact. |
| <2> Anode | Current entry path during conduction | Connected to AC line or DC supply; polarity-sensitive for unidirectional operation. |
| <3> Gate | Trigger control input | Receives low-energy pulse to initiate conduction; requires RGK = 1 kΩ per datasheet test condition. |
Key Features
| Feature | Design Value |
|---|---|
| P-gate full diffusion | Enables consistent turn-on characteristics and improved dV/dt immunity versus planar gate SCRs. |
| TO-202AA package | Provides mechanical robustness and standardized mounting for automated assembly and heatsink integration. |
| UL94V-0 epoxy | Meets flammability safety standard for consumer equipment enclosures without additional fire barriers. |
| Standard quality grade | Qualified for computers, office equipment, audio/video gear, and home appliances per Renesas classification. |

Use Value: Gate trigger sensitivity (≤0.2 mA) allows direct drive from low-power isolation ICs without buffer transistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST3P4M | Same VDRM (400 V), IT(AV) = 3 A, but TO-220AB package; Rth(j-c) = 6.5 °C/W (lower thermal resistance). | Requires different PCB footprint and heatsink interface; better thermal performance but larger board area. | Select when higher thermal margin is needed and TO-220 layout is acceptable. |
| BT169G | Lower IT(AV) = 0.8 A, VDRM = 400 V, TO-92 package; gate trigger current ≤ 50 µA (more sensitive). | Not suitable for 3 A loads; limited to signal-level or pilot SCR applications. | Use only as gate driver for larger SCRs-not as direct replacement for 3P4MH(DY)-AZ load switching. |
Compared with ST3P4M and BT169G, the 3P4MH(DY)-AZ offers optimized balance of TO-202AA form factor, 3 A current rating, and gate drive simplicity for cost-sensitive consumer-grade AC control-without requiring PCB redesign or derating.

FAQ
What is the maximum junction temperature rating for the 3P4MH(DY)-AZ?
The 3P4MH(DY)-AZ has a specified junction temperature range of −40°C to +125°C. This rating applies under all operating conditions defined in the datasheet, including average on-state current of 3 A at case temperature 87°C. Exceeding +125°C risks parametric shift and accelerated degradation; thermal design must ensure Tj remains within this limit using the 8 °C/W junction-to-case resistance value.
Does the 3P4MH(DY)-AZ support bidirectional AC switching?
No, the 3P4MH(DY)-AZ is a unidirectional SCR and conducts current only from anode to cathode when triggered. For full-wave AC control, two SCRs must be connected in inverse-parallel or a triac should be used instead. Its gate trigger circuitry and internal structure are optimized for single-quadrant operation, consistent with its use in leading-edge phase-cut dimmers and motor controllers.
What gate resistor value is required for reliable triggering of the 3P4MH(DY)-AZ?
The datasheet specifies RGK = 1 kΩ for all electrical characteristic measurements, including IGT and VGT tests. Using this value ensures compliance with the rated gate trigger current (≤0.2 mA) and voltage (≤0.8 V) under standard test conditions. Deviating significantly from 1 kΩ may cause inconsistent turn-on or excessive gate dissipation; design validation with actual load and waveform is recommended.
Is the 3P4MH(DY)-AZ RoHS compliant?
Yes, the 3P4MH(DY)-AZ complies with the EU RoHS Directive. Renesas Electronics confirms environmental compatibility per applicable regulations, and the device contains no restricted substances above threshold limits. Compliance documentation is available through Renesas' official product environmental reports and can be requested via their inquiry portal.
Can the 3P4MH(DY)-AZ replace a triac in existing dimmer designs?
No, the 3P4MH(DY)-AZ cannot directly replace a triac because it lacks bidirectional conduction capability. Triacs conduct in both directions and enable simpler single-component full-wave control. Replacing a triac with the 3P4MH(DY)-AZ would require dual-SCR inverse-parallel configuration, revised gate drive timing, and updated snubber networks-making it a redesign, not a drop-in substitution.
