Renesas 3P6MH(AE)-AZ

Overview

3P6MH(AE)-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. It features a gate trigger current of ≤0.2 mA, on-state voltage of ≤1.6 V at 10 A, and commutating turn-off time of ≤80 µs-designed for reliable AC power control in consumer lighting and appliance switching circuits.

For engineers reviewing the 3P6MH(AE)-AZ datasheet, 3P6MH(AE)-AZ pinout, 3P6MH(AE)-AZ application, or 3P6MH(AE)-AZ equivalent, key selection criteria include its 600 V V_DRM/V_RRM, 65–70 A surge capability, 8 °C/W junction-to-case thermal resistance, and UL94V-0 flame-retardant epoxy packaging-critical for thermally constrained, safety-certified mains-switching designs.

Technical Context

The 3P6MH(AE)-AZ is a P-gate, fully diffused mold-type SCR optimized for phase-control and zero-crossing switching in resistive and inductive AC loads. Its low I_GT (≤0.2 mA) and V_GT (≤0.8 V) enable direct drive from microcontroller GPIOs or low-power logic interfaces without external amplification.

With a critical dV/dt rating of ≥3 V/µs at 125°C and holding current of 1–5 mA, it supports stable latching in noisy industrial environments while maintaining immunity to false triggering under transient line conditions.

FAQ

What is the maximum junction temperature specification for the 3P6MH(AE)-AZ?

The 3P6MH(AE)-AZ has a specified junction temperature range of −40°C to +125°C. This rating is validated per the Absolute Maximum Ratings table in the original Renesas datasheet D13533EJ3V0DS. Operation beyond +125°C risks irreversible degradation of the P-gate diffusion structure and increased leakage current. Derating curves in Figure 11 confirm 3 A average current is sustainable only when case temperature remains ≤87°C-requiring appropriate heatsinking for continuous use. The 3P6MH(AE)-AZ must be operated within this thermal envelope to ensure reliability and compliance with its Standard quality grade classification.

Does the 3P6MH(AE)-AZ have a specified gate trigger voltage?

Yes, the 3P6MH(AE)-AZ has a maximum gate trigger voltage (V_GT) of 0.8 V under test conditions of V_DM = 6 V and R_L = 100 Ω at T_j = 25°C, as stated in the Electrical Characteristics table. This low V_GT enables direct interfacing with 3.3 V or 5 V logic outputs without level-shifting. The 3P6MH(AE)-AZ also specifies a gate non-trigger voltage (V_GD) of ≥2 V at 125°C, ensuring noise immunity in high-temperature environments. These values are measured with RGK = 1 kΩ and are critical for designing robust gate drive circuits that avoid false triggering or insufficient turn-on.

Can the 3P6MH(AE)-AZ be used in DC switching applications?

No, the 3P6MH(AE)-AZ is not rated for DC switching. As a unidirectional SCR, it relies on natural current zero-crossing to commutate and turn off-making it unsuitable for pure DC loads without external forced-commutation circuitry. Its datasheet specifies parameters exclusively for AC operation: single half-wave conduction, sine half-wave surge testing, and phase-control applications. Attempting DC switching with the 3P6MH(AE)-AZ will result in latch-up and device failure. For DC applications, a MOSFET, IGBT, or bidirectional switch such as a triac or back-to-back SCR pair should be selected instead of the 3P6MH(AE)-AZ.

What is the thermal resistance from junction to case for the 3P6MH(AE)-AZ?

The junction-to-case thermal resistance (R_th(j-c)) of the 3P6MH(AE)-AZ is 8 °C/W, measured under DC conditions per Figure 13 of the Renesas datasheet D13533EJ3V0DS. This value applies to the TO-202AA package with the cathode tab mounted to a heatsink using recommended torque and thermal interface material. It reflects steady-state conduction and is essential for calculating maximum allowable power dissipation: P_max = (T_j(max) − T_c) / R_th(j-c). For example, at T_c = 87°C, P_max ≈ (125 − 87) / 8 = 4.75 W-consistent with its 3 A I_T(AV) rating. This R_th(j-c) is confirmed for the 3P6MH(AE)-AZ and not extrapolated from similar devices.

Is the 3P6MH(AE)-AZ RoHS compliant?

The 3P6MH(AE)-AZ was manufactured prior to the 2006 RoHS Directive enforcement and is not RoHS compliant. Its datasheet (D13533EJ3V0DS, issued April 2002) predates EU RoHS requirements, and Renesas does not list this part in its current RoHS-compliant product portfolio. Lead content exceeds the 0.1% weight-in-homogeneous-material threshold, particularly in solderable terminations and internal metallization. For new designs requiring RoHS compliance, consider modern alternatives such as the STMicroelectronics TN6050H-600 or Littelfuse Q6006LH4, which offer comparable ratings and full RoHS certification. The 3P6MH(AE)-AZ remains available for legacy repair and maintenance where RoHS exemption applies.
