Product details
Overview
3P6MH-AZ from Renesas Electronics is a 3 A average on-state current, 600 V repetitive peak off-state voltage silicon-controlled rectifier (SCR) in a TO-202AA molded package with P-gate fully diffused construction. It features 80 µs commutating turn-off time, 1.6 V maximum on-state voltage at 10 A, and 50 A/µs critical rate of rise of on-state current. It is used in noncontact switching circuits for consumer electronics, lighting controls, and industrial equipment.
For engineers reviewing the 3P6MH-AZ datasheet, 3P6MH-AZ pinout, 3P6MH-AZ application, or 3P6MH-AZ equivalent, key selection criteria include its 600 V VDRM/VRRM rating, gate trigger current ≤0.2 mA, holding current range of 1–5 mA, thermal resistance Rth(j-c) = 8 °C/W, and compliance with UL94V-0 flame-retardant epoxy packaging.
Technical Context
The 3P6MH-AZ operates as a unidirectional thyristor requiring gate-triggered latching into conduction, with zero-voltage turn-off only upon current interruption. Its fully diffused P-gate structure ensures stable triggering across temperature (−40 to +125 °C junction range) and low dV/dt sensitivity (≥3 V/µs at 125 °C).
It supports single half-wave AC operation up to 3 A average current at Tc = 87 °C, delivers 4.7 A RMS on-state capability, and withstands 70 A surge current (60 Hz sine half-wave, 1 cycle). Gate drive is compatible with standard TTL/CMOS-compatible trigger sources via 100 Ω load and 6 V reverse gate limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - Maximum repetitive blocking voltage in forward and reverse directions; defines usable AC line voltage headroom (e.g., 240 VAC systems with safety margin) |
| IT(AV) | 3 A @ Tc = 87 °C - Average on-state current rating under specified heatsink conditions; determines continuous power handling in phase-control dimmers or motor controllers |
| VTM | ≤1.6 V @ IT = 10 A - On-state voltage drop at rated surge; directly impacts conduction loss and thermal design (e.g., ~16 W dissipation at 10 A) |
| IGT / VGT | ≤0.2 mA / ≤0.8 V - Low gate trigger requirements enable direct drive from microcontrollers or optocouplers without amplification |
| Tq | ≤80 µs - Commutating turn-off time at 125 °C; sets minimum off-time for forced-commutated inverters or high-frequency AC switches |
| Rth(j-c) | 8 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing when mounted on metal tablet per TO-202AA footprint |
| dIT/dt | 50 A/µs - Minimum required rate of rise for reliable turn-on without false triggering; constrains snubber design in inductive loads |
Pinout & Package
3P6MH-AZ uses the TO-202AA molded plastic package (standard weight: 1.4 g), featuring three leads in inline configuration with cathode, anode, and gate terminals. The package meets UL94V-0 flammability rating and supports mechanical jig-based lead forming and heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| <1> Cathode | Current exit path during conduction | Connected to load return or ground reference; must handle full on-state current and be thermally coupled to heatsink |
| <2> Anode | Current entry path during conduction | Connected to AC line or DC supply; polarity-sensitive-reverse connection prevents latching |
| <3> Gate | Control terminal for turn-on initiation | Receives low-energy pulse to trigger conduction; requires current-limiting resistor and protection against noise-induced false triggers |
Key Features
| Feature | Design Value |
|---|---|
| TO-202AA molded package | Compact, lightweight, and flame-retardant (UL94V-0); enables surface-mount–compatible manual assembly and standardized heatsink interface |
| P-gate fully diffused structure | Ensures consistent gate sensitivity and stable latching behavior over −40 to +125 °C operating range |
| Low IGT (≤0.2 mA) | Reduces gate drive power requirement and allows direct interfacing with logic-level outputs or low-power optocouplers |
| 80 µs commutation time (Tq) | Supports operation in medium-frequency AC switching applications (e.g., 400 Hz control) with predictable turn-off behavior |
| 8 °C/W thermal resistance (Rth(j-c)) | Enables efficient heat transfer to external heatsink; simplifies thermal management for 3 A continuous duty in compact enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics TS600-600 | 600 V VDRM, 6 A IT(AV), TO-220AB package, higher thermal mass but larger footprint | Better suited for higher-current, lower-frequency heater control where PCB space permits | Select when >3 A average current or enhanced surge robustness (100 A ITSM) is required |
| ON Semiconductor 2N6504 | 600 V VDRM, 4 A IT(AV), TO-202AA package, slightly higher VTM (1.7 V) and longer Tq (100 µs) | Compatible pinout but requires gate drive redesign due to 1.5× higher IGT (0.3 mA) | Acceptable for cost-sensitive replacements where 0.2 mA IGT margin is not critical |
Compared with the 3P6MH-AZ, the TS600-600 offers higher current capacity and surge tolerance in a larger package, while the 2N6504 matches the TO-202AA form factor but trades off gate sensitivity and turn-off speed-making the 3P6MH-AZ optimal for space-constrained, low-power, fast-switching AC control.

FAQ
What is the maximum junction temperature rating for the 3P6MH-AZ?
The 3P6MH-AZ has a specified junction temperature range of −40 to +125 °C. This rating is validated under steady-state thermal conditions with proper heatsinking per the Rth(j-c) = 8 °C/W specification. Operation beyond +125 °C risks parametric shift and accelerated degradation. The 3P6MH-AZ must be derated linearly above 87 °C case temperature to maintain its 3 A IT(AV) rating.
Can the 3P6MH-AZ be used in DC switching applications?
The 3P6MH-AZ is a conventional SCR and cannot commutate itself in DC circuits-it remains latched until anode current falls below the holding current (IH = 1–5 mA). For DC switching, external forced commutation (e.g., LC snubber or auxiliary transistor circuit) is required. The 3P6MH-AZ is optimized for AC line-frequency or medium-frequency phase-control, not standalone DC interruption.
What gate drive circuit is recommended for reliable triggering of the 3P6MH-AZ?
A series resistor between the gate driver and pin <3> limits peak gate current to ≤1 A (IFGM rating) and ensures IGT ≤0.2 mA is met at VGT ≤0.8 V. With a 5 V logic source, a 22 kΩ resistor provides safe margin. A 0.1 µF capacitor across RGK suppresses noise. The 3P6MH-AZ gate must never be left floating-always tie to cathode via ≥1 kΩ when inactive.
Is the 3P6MH-AZ RoHS compliant?
Yes, the 3P6MH-AZ complies with the EU RoHS Directive. Renesas Electronics confirms lead-free terminations and absence of restricted substances per its environmental compliance documentation. The device uses UL94V-0 flame-retardant epoxy and meets JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/60% RH), making it suitable for standard reflow and hand-soldering processes.
How does the 3P6MH-AZ compare to the 3P4MH variant?
The 3P6MH-AZ and 3P4MH share identical package, thermal specs, and gate characteristics, differing only in voltage rating: 3P6MH-AZ has 600 V VDRM/VRRM and 700 V non-repetitive peaks, while 3P4MH is rated for 400 V/500 V. All other parameters-including IT(AV), Tq, IGT, and Rth(j-c)-are identical. Select 3P6MH-AZ for 230–240 VAC systems with safety margin; 3P4MH suffices for 115 VAC or low-voltage DC-fed AC inverters.
