Product details
Overview
2S4M(6)-AZ from Renesas Electronics is a 400 V repetitive peak off-state voltage, 2 A average on-state current, P-gate fully diffused mold silicon-controlled rectifier (SCR) in TO-202AA package, designed for high-speed switching in inverter and solenoid valve drive circuits.
For engineers reviewing the 2S4M(6)-AZ datasheet, 2S4M(6)-AZ pinout, 2S4M(6)-AZ application, or 2S4M(6)-AZ equivalent, key selection criteria include commutating turn-off time (15 µs), critical dV/dt (10 V/µs), gate trigger current (300 µA), on-state voltage (2.2 V at 4 A), and junction-to-case thermal resistance (10 °C/W).
Technical Context
This SCR employs a P-gate fully diffused structure enabling fast turn-on (2 µs) and controlled commutation (15 µs Tq). Its design supports reliable blocking at 400 V (VDRM/VRRM) with low gate trigger sensitivity (IGT ≤ 300 µA, VGT ≤ 0.8 V) under standard test conditions (RGK = 1 kΩ, Tj = 25°C).
It operates across −40°C to +125°C junction temperature range with thermal resistance Rth(j-c) = 10 °C/W and Rth(j-a) = 75 °C/W. The device meets UL94V-0 flammability rating and is rated for standard-grade applications including consumer electronics and industrial controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 400 V - maximum repetitive off-state voltage sustainable without conduction |
| IT(AV) | 2 A at Tc = 77°C, single half-wave, 180° conduction - continuous current capability with heatsink |
| Tq | 15 µs - commutating turn-off time at Tj = 125°C, critical for inverter switching frequency limits |
| IGT | ≤300 µA - low gate current requirement enables direct drive from microcontroller GPIO or small logic buffers |
| VTM | ≤2.2 V at ITM = 4 A - forward voltage drop determines conduction loss and thermal load at rated current |
| dV/dt | 10 V/µs - minimum rate of rise of off-state voltage before false triggering, defines snubber design needs |
| Rth(j-c) | 10 °C/W - junction-to-case thermal resistance governs heatsink sizing for power dissipation management |
Pinout & Package
Package: TO-202AA - molded plastic case with integral heat-transfer tab, UL94V-0 rated, 1.4 g weight, compatible with standard lead-forming jigs and heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Main current return path; electrically connected to metal tab for thermal and electrical grounding |
| 2 | Anode | Main current input terminal; carries full load current during conduction phase |
| 3 | Gate | Control input; triggers conduction when IGT ≥ 300 µA applied with proper dV/dt margin |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | Turn-on time ≤2 µs and commutating turn-off time ≤15 µs enable operation up to ~10 kHz in forced-commutated inverters |
| P-gate fully diffused structure | Improves gate sensitivity and uniformity of conduction, reducing IGT variation across production lots |
| TO-202AA package | Enables compact PCB layout and direct heatsink mounting via metal tab; eliminates need for separate thermal interface hardware |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics TS420-400 | 400 V VDRM, 2 A IT(AV), but higher IGT (500 µA max) and slower Tq (20 µs) | Less suitable for high-frequency inverters requiring tight commutation timing | Prefer 2S4M(6)-AZ where low gate drive burden and fast turn-off are critical |
| ON Semiconductor 2N6504 | 400 V VDRM, 4 A IT(AV), TO-220 package, higher thermal mass but larger footprint | Better for higher-current loads but requires PCB redesign and larger heatsink | Choose 2S4M(6)-AZ for space-constrained designs needing 2 A rating in TO-202AA |
Compared with TS420-400 and 2N6504, the 2S4M(6)-AZ delivers superior gate sensitivity and faster commutation in a compact TO-202AA package-making it optimal for cost-sensitive, space-limited inverter and solenoid control where 2 A average current suffices.

FAQ
What is the maximum repetitive peak off-state voltage rating for the 2S4M(6)-AZ?
The 2S4M(6)-AZ has a repetitive peak off-state voltage (VDRM) and repetitive peak reverse voltage (VRRM) rating of 400 V. This rating is verified at Tj = 25°C with RGK = 1 kΩ and defines the maximum sustained AC or DC voltage the device can block in its off state without unintended conduction. Exceeding this voltage risks breakdown or latch-up.
Does the 2S4M(6)-AZ require a heatsink in typical 2 A continuous operation?
Yes-the 2S4M(6)-AZ requires a heatsink when operating at its rated 2 A average on-state current (IT(AV)), because its junction-to-case thermal resistance is 10 °C/W and on-state voltage reaches 2.2 V at 4 A. Without thermal management, junction temperature will exceed the 125°C maximum under sustained load. The TO-202AA metal tab is designed for direct heatsink mounting.
What is the gate trigger current specification for the 2S4M(6)-AZ, and how is it tested?
The 2S4M(6)-AZ has a maximum gate trigger current (IGT) of 300 µA, measured at Tj = 25°C with VDM = 6 V and RL = 100 Ω. This low IGT enables direct drive from low-power logic outputs or microcontroller pins without external amplification-reducing system component count and board space while maintaining robust turn-on margin.
Can the 2S4M(6)-AZ be used in automotive applications?
No-the 2S4M(6)-AZ is classified as a Standard-grade Renesas product intended for consumer electronics, office equipment, and industrial controls-not automotive systems. It lacks AEC-Q101 qualification, extended temperature validation beyond −40°C to +125°C, or the enhanced process controls required for transportation-grade reliability. Automotive use requires explicit written consent from Renesas.
What is the commutating turn-off time (Tq) of the 2S4M(6)-AZ, and why does it matter?
The 2S4M(6)-AZ has a commutating turn-off time (Tq) of 15 µs at Tj = 125°C, IT = 2 A, VDM = 2/3 VDRM, VR = 50 V, and dV/dt = 10 V/µs. This parameter determines the minimum time required to safely commutate the SCR in forced-commutated inverters; shorter Tq allows higher switching frequencies and reduces snubber losses in the 2S4M(6)-AZ-based design.
