Product details
Overview
3P4MH(YM)-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(YM)-AZ datasheet, 3P4MH(YM)-AZ pinout, 3P4MH(YM)-AZ application, or 3P4MH(YM)-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
This thyristor operates as a latching unidirectional switch triggered by a low-energy gate pulse. Its P-gate fully diffused structure ensures stable triggering with VGT ≤ 0.8 V and IGT ≤ 0.2 mA under standard test conditions (VDM = 6 V, RL = 100 Ω).
Designed for half-wave AC control, it supports 3 A average on-state current at Tc = 87°C with 4.7 A RMS rating and withstands 65 A non-repetitive surge (50 Hz, 1 cycle). Critical dV/dt immunity is ≥3 V/µs at 125°C, and thermal resistance from junction-to-case is 8°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 blocking capability in phase-control circuits. |
| IT(AV) | 3 A at Tc = 87°C - Continuous average load current handling under heatsink-cooled conditions; sets thermal design baseline. |
| VTM | 1.6 V at IT = 10 A - On-state voltage drop determining conduction loss and self-heating during active conduction. |
| IGT / VGT | ≤0.2 mA / ≤0.8 V - Minimum gate drive energy required for reliable turn-on; enables direct microcontroller GPIO triggering. |
| Tq | 80 µs - Commutating turn-off time at Tj = 125°C; constrains minimum zero-crossing interval in forced-commutated AC applications. |
| dV/dt | ≥3 V/µs at Tj = 125°C - Minimum rate of rising off-state voltage before false triggering; dictates snubber design requirements. |
| Rth(j-c) | 8°C/W - Junction-to-case thermal resistance; used with heatsink thermal resistance to calculate maximum allowable case temperature. |
Pinout & Package
3P4MH(YM)-AZ uses the TO-202AA molded package (standard weight: 1.4 g), featuring flame-retardant UL94V-0 epoxy resin and lead-forming compatibility for mechanical mounting jigs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| <1> Cathode | Current exit terminal during conduction | Main current path return node; electrically tied to heatsink when mounted with insulating washer removed. |
| <2> Anode | Current entry terminal during conduction | High-side connection to AC line or load; carries full load current and must be routed with adequate creepage/clearance. |
| <3> Gate | Control input for turn-on initiation | Low-power trigger node requiring <0.2 mA; sensitive to noise-requires short, shielded routing and local RC filtering. |
Key Features
| Feature | Design Value |
|---|---|
| TO-202AA package | Small footprint and lightweight mechanical form factor enabling compact PCB layout and manual or jig-assisted lead forming. |
| UL94V-0 epoxy molding | Flame-retardant encapsulation meeting safety standards for consumer and industrial end-equipment certification. |
| P-gate fully diffused structure | Guarantees consistent low-level gate sensitivity (IGT ≤ 0.2 mA) across temperature and device lifetime. |
| 80 µs commutating turn-off time | Enables use in line-synchronized AC power control where forced commutation timing is tightly constrained. |
| Junction temp range −40°C to +125°C | Supports operation in uncontrolled ambient environments including enclosed industrial enclosures and automotive under-hood proximity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST3P04 | Same 400 V VDRM and 3 A IT(AV), but TO-92 package (smaller, lower thermal mass); Rth(j-c) = 15°C/W vs. 8°C/W. | Suitable for low-duty-cycle or naturally cooled applications; not recommended for continuous 3 A conduction without forced air. | Select ST3P04 only if board space is critical and thermal load remains below 1.5 A average. |
| BT169G | Lower 1 A IT(AV) rating and 400 V VDRM; gate trigger current higher (IGT ≤ 200 µA vs. ≤0.2 mA); TO-92 package. | Limited to signal-level AC switching (e.g., indicator lamps, small relays); cannot replace 3P4MH(YM)-AZ in motor or solenoid loads. | Use BT169G only for sub-500 mA resistive loads where gate drive margin and thermal headroom are non-critical. |
Compared with ST3P04 and BT169G, the 3P4MH(YM)-AZ provides superior thermal performance and gate sensitivity for sustained 3 A switching, making it the preferred choice for industrial-grade AC load control where reliability and heatsink integration matter.

FAQ
What is the maximum junction temperature rating for the 3P4MH(YM)-AZ?
The 3P4MH(YM)-AZ has a specified junction temperature range of −40°C to +125°C. This allows operation in demanding environments such as enclosed industrial cabinets or near heat-generating components. Derating of IT(AV) is required above 87°C case temperature, per Figure 11 in the original datasheet D13533EJ3V0DS. Thermal design must ensure Rth(j-c) + Rth(c-sink) + Rth(sink-amb) keeps Tj ≤ 125°C under worst-case load.
Can the 3P4MH(YM)-AZ be directly driven by a microcontroller GPIO pin?
Yes-the 3P4MH(YM)-AZ can be directly triggered by most 3.3 V or 5 V microcontroller GPIO pins due to its low gate trigger current (IGT ≤ 0.2 mA) and gate trigger voltage (VGT ≤ 0.8 V). However, a series current-limiting resistor (e.g., 1–2.2 kΩ) and optional RC snubber (e.g., 100 Ω + 100 nF) are recommended to suppress noise-induced false triggering and protect the GPIO driver.
What is the commutating turn-off time (Tq) specification for the 3P4MH(YM)-AZ?
The commutating turn-off time Tq for the 3P4MH(YM)-AZ is 80 µs, measured at Tj = 125°C, IT = 3 A, diR/dt = 15 A/µs, VR ≥ 25 V, VDM = 2/3 VDRM, and dVD/dt = 1 V/µs. This parameter determines the minimum time required for the device to regain blocking capability after current interruption-critical for designing forced-commutated AC controllers and snubberless triac replacement circuits.
Is the 3P4MH(YM)-AZ RoHS compliant?
Yes-the 3P4MH(YM)-AZ complies with the EU RoHS Directive. Renesas Electronics confirms environmental compliance for this part, including restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. Full material declarations and test reports are available upon request from Renesas sales offices or authorized distributors.
What package type does the 3P4MH(YM)-AZ use, and what are its mechanical dimensions?
The 3P4MH(YM)-AZ uses the TO-202AA molded package, with standardized outline per JEDEC TO-202. Key dimensions include body width ≈ 6.5 mm, length ≈ 10.5 mm, and lead spacing ≈ 2.54 mm. The package features UL94V-0 flame-retardant epoxy and is compatible with standard TO-202 mounting hardware and heatsinks. Detailed mechanical drawings are provided in Renesas datasheet D13533EJ3V0DS.
