Product details
Overview
3P4MH(6)-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. Designed for noncontact switching in consumer electronics power control circuits.
For engineers reviewing the 3P4MH(6)-AZ datasheet, 3P4MH(6)-AZ pinout, 3P4MH(6)-AZ application, or 3P4MH(6)-AZ equivalent, key selection criteria include repetitive peak off-state voltage (VDRM = 400 V), critical dV/dt immunity (3 V/µs at 125°C), junction-to-case thermal resistance (8 °C/W), and gate trigger sensitivity (VGT ≤ 0.8 V).
Technical Context
The 3P4MH(6)-AZ is a P-gate, fully diffused mold-type SCR optimized for phase-control and AC switching applications. Its design supports reliable turn-on with low gate drive (IGT ≤ 0.2 mA, VGT ≤ 0.8 V) and maintains stable blocking up to 400 V under repetitive conditions (VDRM/VRRM = 400 V).
It delivers 3 A average on-state current at case temperature Tc = 87°C with single half-wave conduction (θ = 180°), and withstands surge currents up to 65 A (50 Hz, sine half-wave, 1 cycle). Thermal performance is characterized by Rth(j-c) = 8 °C/W and Rth(j-a) = 75 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 400 V - Maximum repetitive off-state voltage before conduction; defines AC line voltage compatibility up to 280 V RMS. |
| IT(AV) | 3 A at Tc = 87°C - Continuous average load current capability with heatsink; sets minimum heatsink sizing requirement. |
| VTM | ≤1.6 V at IT = 10 A - On-state voltage drop determining conduction loss and thermal dissipation in power stage. |
| IGT / VGT | ≤0.2 mA / ≤0.8 V - Low gate drive demand enabling direct interface with microcontroller GPIO or optocoupler outputs. |
| Tq | ≤80 µs - Commutating turn-off time limiting minimum zero-crossing interval in phase-angle control designs. |
| dV/dt | ≥3 V/µs at Tj = 125°C - Minimum rate of voltage rise the device blocks without false triggering; impacts snubber design. |
| Rth(j-c) | 8 °C/W - Junction-to-case thermal resistance; used to calculate junction temperature rise above heatsink temperature. |
Pinout & Package
3P4MH(6)-AZ is housed in a TO-202AA molded plastic package with three leads: anode, cathode, and gate. The package is flame-retardant (UL94V-0) and weighs 1.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| <1> Cathode | Current exit terminal during conduction | Connected to load return path; common reference for gate drive and sensing. |
| <2> Anode | Current entry terminal during conduction | Connected to AC line or high-side power rail; carries full load current. |
| <3> Gate | Control input for turn-on initiation | Receives low-energy pulse to trigger conduction; requires IGT ≤ 0.2 mA and VGT ≤ 0.8 V. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate trigger sensitivity | IGT ≤ 0.2 mA enables direct drive from logic-level sources without amplification. |
| Robust dV/dt immunity | 3 V/µs at 125°C reduces risk of false triggering in noisy AC environments. |
| Optimized thermal path | Rth(j-c) = 8 °C/W supports efficient heat transfer to external heatsink in compact layouts. |
| Flame-retardant packaging | UL94V-0 epoxy resin meets safety standards for consumer equipment enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT169G | Lower VDRM (400 V same), but IT(AV) = 0.8 A; TO-92 package; higher VTM (1.7 V typ). | Suitable only for sub-1 A loads; not recommended for motor or heater control requiring 3 A continuous. | Select 3P4MH(6)-AZ when ≥3 A average current and robust thermal performance (Rth(j-c) = 8 °C/W) are required. |
| TYN612 | Higher IT(AV) = 12 A, VDRM = 600 V, TO-220 package; larger footprint and higher gate drive (IGT = 15 mA). | Better suited for industrial 3-phase or high-power single-phase loads; over-specified for consumer-grade 3 A applications. | Choose 3P4MH(6)-AZ for cost-sensitive, space-constrained consumer designs where TO-202AA fit and low gate drive matter. |
Compared with BT169G and TYN612, the 3P4MH(6)-AZ offers optimal balance of 3 A current rating, TO-202AA compactness, ultra-low gate drive (0.2 mA), and 400 V blocking-making it ideal for cost-effective, thermally constrained AC switching in consumer electronics.

FAQ
What is the maximum repetitive peak off-state voltage (VDRM) for the 3P4MH(6)-AZ?
The 3P4MH(6)-AZ has a repetitive peak off-state voltage (VDRM) of 400 V, verified per its datasheet D13533EJ3V0DS. This rating ensures safe operation with 230 V AC mains (peak ≈ 325 V) plus margin for transients. Exceeding this voltage risks unintended conduction or device failure.
Does the 3P4MH(6)-AZ require a heatsink in typical operation?
Yes-the 3P4MH(6)-AZ is rated for 3 A average on-state current only at Tc = 87°C, meaning a heatsink is required to maintain case temperature within limit. Without heatsinking, its usable current drops significantly due to Rth(j-a) = 75 °C/W; derating curves in Figure 11 of the datasheet confirm this dependency.
What is the gate trigger voltage (VGT) specification for the 3P4MH(6)-AZ?
The 3P4MH(6)-AZ has a maximum gate trigger voltage (VGT) of 0.8 V at Tj = 25°C, with VDM = 6 V and RL = 100 Ω. This low threshold allows direct drive from 3.3 V or 5 V logic outputs, reducing external component count compared to SCRs requiring higher gate voltage.
Can the 3P4MH(6)-AZ be used in 60 Hz AC applications?
Yes-the 3P4MH(6)-AZ supports 60 Hz operation, with surge on-state current ITSM rated at 70 A for 60 Hz sine half-wave (1 cycle). Its commutating turn-off time Tq ≤ 80 µs is sufficient for 60 Hz zero-crossing intervals (≈8.3 ms), ensuring reliable re-blocking after each half-cycle.
Is the 3P4MH(6)-AZ RoHS compliant?
Yes-the 3P4MH(6)-AZ complies with EU RoHS Directive requirements. Renesas Electronics confirms environmental compliance for this part in documentation D13533EJ3V0DS, and it uses lead-free terminations and UL94V-0 flame-retardant epoxy consistent with RoHS material restrictions.
