Product details
Overview
3P4MH(YE)-AZ from Renesas Electronics is a 3 A average on-state current, 400 V repetitive peak off-state voltage P-gate fully diffused molded SCR in TO-202AA package, rated for junction temperatures from −40°C to +125°C and used in noncontact switching for consumer electronics, audio equipment, and light industrial controls.
For engineers reviewing the 3P4MH(YE)-AZ datasheet, 3P4MH(YE)-AZ pinout, 3P4MH(YE)-AZ application, or 3P4MH(YE)-AZ equivalent, key selection criteria include its 1.6 V on-state voltage at 10 A, 0.2 mA gate trigger current, 80 µs commutating turn-off time, and UL94V-0 flame-retardant epoxy encapsulation.
Technical Context
The 3P4MH(YE)-AZ operates as a unidirectional silicon-controlled rectifier with gate-triggered latching conduction. Its P-gate fully diffused structure ensures stable triggering and robust dV/dt immunity of 3 V/µs at 125°C under 2/3 VDRM stress.
It supports single half-wave AC operation with IT(AV) = 3 A at Tc = 87°C and delivers IT(RMS) = 4.7 A. Thermal resistance is 8°C/W (junction-to-case) and 75°C/W (junction-to-ambient), enabling direct heatsink mounting via its TO-202AA tab.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 3 A at Tc = 87°C, single half-wave, 180° conduction - defines continuous power-handling capability in thermally managed AC switch designs |
| VDRM / VRRM | 400 V - maximum repetitive off-state voltage before unintended conduction; sets AC line-voltage compatibility up to 280 V RMS |
| VTM | 1.6 V at IT = 10 A - determines conduction loss and thermal dissipation in on-state operation |
| IGT | 0.2 mA max at VDM = 6 V, RL = 100 Ω - enables low-power gate drive circuitry with minimal driver component count |
| Tq | 80 µs max at Tj = 125°C, IT = 3 A - specifies minimum commutation interval required for reliable forced turn-off in phase-control or inverter circuits |
| dV/dt | 3 V/µs min at Tj = 125°C, VDM = 2/3 VDRM - indicates immunity to false triggering from fast-rising transients in noisy AC environments |
Pinout & Package
3P4MH(YE)-AZ uses the TO-202AA molded package with integral heatsink tab. Dimensions conform to JEDEC TO-202AA standard; lead frame material is copper alloy with tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| <1> Cathode | Current return path during conduction | Low-impedance terminal connected to heatsink tab; must be electrically isolated if heatsink is grounded |
| <2> Anode | Main power input during forward conduction | High-current input node; polarity-sensitive - reverse connection prevents latching |
| <3> Gate | Trigger control input | Low-energy control terminal; requires ≥0.8 V and ≥0.2 mA pulse to initiate conduction |
Key Features
| Feature | Design Value |
|---|---|
| UL94V-0 flame-retardant epoxy molding | Meets international safety standards for flammability; eliminates need for external fire barriers in end-equipment enclosures |
| TO-202AA mechanical footprint | Enables drop-in replacement in legacy board layouts designed for industry-standard 3-pin molded SCRs |
| 50 A/µs critical dIT/dt rating | Supports rapid current rise without false turn-on during inductive load switching |
| 20 A²s fusing I²t rating | Defines single-pulse surge withstand capability for short-circuit protection coordination with upstream fuses |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics TS3A40 | 4 A IT(AV), 400 V VDRM, TO-220AB package, higher IGT (1.5 mA max) | Requires stronger gate drive; better suited for high-reliability industrial panels with larger PCB real estate | Prefer when higher surge current (ITSM = 100 A) and lower Rth(j-c) (1.5°C/W) are needed for forced-air-cooled systems |
| ON Semiconductor 2N6504 | 3 A IT(AV), 400 V VDRM, TO-202AA package, identical pinout, but higher VTM (1.8 V) and longer Tq (100 µs) | Slightly higher conduction loss and slower turn-off limit use in high-frequency phase control | Acceptable for cost-sensitive consumer-grade dimmers where 0.2 V higher VTM and 20 µs longer Tq are tolerable |
Compared with STMicroelectronics TS3A40 and ON Semiconductor 2N6504, the 3P4MH(YE)-AZ offers the lowest gate trigger current (0.2 mA) and shortest commutating turn-off time (80 µs) in TO-202AA, making it optimal for space-constrained, low-power gate-drive designs requiring fast, energy-efficient AC switching.

FAQ
What is the maximum junction temperature rating for the 3P4MH(YE)-AZ?
The 3P4MH(YE)-AZ has a specified junction temperature range of −40°C to +125°C. This allows reliable operation in enclosed consumer electronics enclosures and industrial control cabinets without active cooling, provided thermal design maintains Tj ≤ 125°C under worst-case IT(AV) and ambient conditions.
Does the 3P4MH(YE)-AZ support bidirectional AC switching?
No, the 3P4MH(YE)-AZ is a unidirectional SCR and conducts only during the positive half-cycle of AC voltage when properly triggered. For full-wave AC control, two 3P4MH(YE)-AZ devices must be connected in inverse-parallel, or a triac such as the BT136 should be used instead.
What is the gate trigger voltage requirement for the 3P4MH(YE)-AZ?
The 3P4MH(YE)-AZ requires a maximum gate trigger voltage (VGT) of 0.8 V under test conditions of VDM = 6 V and RL = 100 Ω. This low threshold enables compatibility with standard 3.3 V or 5 V logic-level drivers when combined with appropriate series resistance to limit IGT to ≤0.2 mA.
Can the 3P4MH(YE)-AZ be mounted directly to a heatsink?
Yes - the TO-202AA package features an integral metal tab that serves as the cathode terminal and provides direct thermal conduction to an external heatsink. Electrical isolation (e.g., mica washer + silicone grease) is required if the heatsink is grounded, as the cathode is internally connected to the tab.
Is the 3P4MH(YE)-AZ RoHS compliant?
Yes, the 3P4MH(YE)-AZ complies with the EU RoHS Directive. Renesas Electronics confirms compliance for this device family in accordance with applicable environmental regulations, including restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE substances.
