Product details
Overview
5P4SMA(YC)-AZ from Renesas Electronics is a resin-molded silicon-controlled rectifier (SCR) rated for 5 A average on-state current at TC = 94°C, 400 V repetitive peak off-state voltage (VDRM), and 1.4 V maximum on-state voltage at 10 A. It features 50 A/μs critical rate of rise of on-state current (dIT/dt), 10 mA gate trigger current, and is designed for phase-controlled AC power regulation in household appliance motor speed control.
For engineers reviewing the 5P4SMA(YC)-AZ datasheet, 5P4SMA(YC)-AZ pinout, 5P4SMA(YC)-AZ application, or 5P4SMA(YC)-AZ equivalent, key selection criteria include verified VDRM/VRRM rating, gate sensitivity (IGT/VGT), thermal resistance (Rth(j-c) = 4.2 °C/W), and TO-220AB-compatible mechanical footprint for direct mounting in solid-state relay and heater control PCBs.
Technical Context
This SCR operates as a latching unidirectional switch triggered by gate current, requiring commutation to turn off. Its 80 A surge on-state current (ITSM, 50 Hz, 1 cycle) supports brief overloads during motor startup, while the 50 μs circuit-commutated turn-off time (tq) enables reliable operation in 50/60 Hz line-frequency applications.
Thermal design relies on junction-to-case conduction (Rth(j-c) = 4.2 °C/W) with DC-rated dissipation up to 10 W at TC = 94°C. The device maintains stable triggering across −40°C to +125°C junction temperature, with gate non-trigger voltage (VGD ≥ 0.2 V) ensuring noise immunity at high temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 400 V - Maximum repetitive blocking voltage in forward/off state; defines AC mains compatibility up to 280 V RMS. |
| IT(AV) | 5 A at TC = 94°C - Continuous average load current capability with heatsink; requires thermal management per Figure 11. |
| VTM | 1.4 V max at ITM = 10 A - On-state conduction loss determines power dissipation (e.g., 7 W at 5 A avg). |
| IGT / VGT | 10 mA / 1.5 V max - Gate drive requirement with 100 Ω load; enables direct microcontroller GPIO triggering via series resistor. |
| dIT/dt | 50 A/μs - Minimum required rate of current rise to avoid false turn-on; mandates snubber design for inductive loads. |
| Rth(j-c) | 4.2 °C/W - Junction-to-case thermal resistance; sets minimum heatsink size for sustained 5 A operation. |
| tq | 50 μs - Circuit-commutated turn-off delay; constrains minimum off-time in phase-angle control at 60 Hz. |
Pinout & Package
5P4SMA(YC)-AZ uses a TO-220AB-compatible 3-pin through-hole package with standard 2.54 mm lead pitch and 17 mm × 12 mm outline. Mounting requires mechanical anchoring and thermal interface to heatsink via case tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Current return path during conduction | Connected to load return; carries full on-state current; electrically tied to metal tab (case). |
| 2 (Anode) | Main power input terminal | Connected to AC line or DC source; blocks reverse voltage up to VRSM = 500 V. |
| 3 (Gate) | Control input for turn-on initiation | Receives low-energy pulse (≥10 mA, ≥1.5 V) to initiate latching conduction; referenced to cathode. |
Key Features
| Feature | Design Value |
|---|---|
| TO-220AB drop-in replacement | Mechanically and electrically compatible with industry-standard TO-220AB footprint and lead form, enabling legacy board reuse. |
| High dIT/dt immunity | 50 A/μs rating prevents spurious turn-on during fast-rising load currents, reducing need for external gate shielding. |
| Low gate trigger threshold | 10 mA IGT allows direct drive from logic-level outputs (e.g., MCU GPIO with 470 Ω series resistor at 5 V). |
| Robust surge capability | 80 A ITSM (50 Hz, 1-cycle) supports motor inrush without derating, simplifying protection coordination with fuses. |
| Wide temperature operation | Specified performance from −40°C to +125°C junction temperature ensures reliability in enclosed heater enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics TS5A4SMA | Same VDRM (400 V), IT(AV) = 5 A, but Rth(j-c) = 5.0 °C/W; higher VGT (2.0 V max). | Requires stronger gate drive; slightly lower thermal efficiency demands larger heatsink for same current. | Prefer when ST's qualification for automotive-grade ambient (−40°C to +150°C) is required. |
| ON Semiconductor S5004L | Identical VDRM/IT(AV), but ITSM = 60 A (50 Hz); tq = 100 μs; PG(AV) = 0.3 W. | Lower surge tolerance and slower turn-off limit use in high-inrush or high-frequency phase control. | Choose where cost sensitivity outweighs need for 80 A surge headroom or fast commutation. |
Compared with TS5A4SMA and S5004L, the 5P4SMA(YC)-AZ offers superior thermal performance (Rth(j-c) = 4.2 °C/W), higher surge rating (80 A), and faster turn-off (50 μs), making it optimal for compact, high-reliability AC power control where thermal margin and transient robustness are critical.

FAQ
What is the maximum repetitive peak off-state voltage (VDRM) for the 5P4SMA(YC)-AZ?
The 5P4SMA(YC)-AZ has a VDRM rating of 400 V, meaning it can reliably block forward voltage up to this level in its off state under repetitive conditions. This rating is validated at Tj = 25°C and defines safe operating margin for 230 VAC or 240 VAC mains applications, with derating applied above 25°C per the datasheet's Figure 12.
Does the 5P4SMA(YC)-AZ require a heatsink for 5 A continuous operation?
Yes, the 5P4SMA(YC)-AZ requires a heatsink to sustain 5 A average on-state current. With Rth(j-c) = 4.2 °C/W and VTM = 1.4 V, power dissipation reaches ~7 W at full load; without heatsinking, junction temperature would exceed 125°C even at modest ambient. Figure 11 confirms 5 A is only achievable at TC = 94°C, necessitating thermal interface to a heatsink.
Can the 5P4SMA(YC)-AZ be driven directly by a 3.3 V microcontroller GPIO?
No - the 5P4SMA(YC)-AZ requires ≥1.5 V gate trigger voltage (VGT) and ≥10 mA gate trigger current (IGT) under standard test conditions. A 3.3 V GPIO alone cannot guarantee sufficient current into the gate-cathode junction; a series resistor (e.g., 220 Ω) yields ~10 mA, but voltage drop may fall below VGT at elevated temperature. A dedicated gate driver or level-shifting buffer is recommended for robust triggering.
What is the critical rate of rise of off-state voltage (dv/dt) specification for the 5P4SMA(YC)-AZ?
The 5P4SMA(YC)-AZ has a dv/dt rating of 40 V/μs at Tj = 125°C and VDM = 2/3 VDRM. This parameter defines the maximum allowable rate of voltage rise across anode-cathode before unintended turn-on occurs. Exceeding this value - common with inductive loads or fast-switching circuits - requires a snubber network (RC across A-K) to suppress transients and ensure reliable blocking behavior.
Is the 5P4SMA(YC)-AZ RoHS compliant and lead-free?
Yes, the 5P4SMA(YC)-AZ complies with EU RoHS Directive requirements. Renesas Electronics confirms lead-free termination and halogen-free molding compound for this device, consistent with their environmental compliance policy stated in the datasheet and corporate documentation. Full material declarations are available upon request from Renesas sales offices.
