Product details
Overview
5P4SMA(YK)-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 dIT/dt rating and is used in motor speed control circuits for household appliances.
For engineers reviewing the 5P4SMA(YK)-AZ datasheet, 5P4SMA(YK)-AZ pinout, 5P4SMA(YK)-AZ application, or 5P4SMA(YK)-AZ equivalent, key selection criteria include gate trigger current (≤10 mA), holding current (6 mA typical), thermal resistance (4.2 °C/W junction-to-case), and compatibility with single-phase half-wave AC control topologies.
Technical Context
This SCR operates as a latching unidirectional power switch controlled by a low-energy gate pulse. Its design supports phase-angle control in resistive and inductive loads, with validated commutation performance (tq ≤ 50 μs at 125°C) and robust dv/dt immunity (≥40 V/μs at 125°C).
It uses standard thyristor physics with PNPN structure, requiring gate-triggered turn-on and natural or forced current-zero turn-off. The device is optimized for conduction angles down to 30° and maintains stable triggering across −40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 400 V - Maximum repetitive off-state voltage before conduction; defines AC line voltage compatibility up to ~280 V RMS. |
| IT(AV) | 5 A at TC = 94°C - Continuous DC-equivalent current handling under heatsink-cooled conditions; requires thermal design per Rth(j-c) = 4.2 °C/W. |
| VTM | 1.4 V max at ITM = 10 A - On-state voltage drop determines conduction loss (e.g., ~7 W at 5 A avg); impacts efficiency and heatsink sizing. |
| IGT / VGT | ≤10 mA / ≤1.5 V - Gate drive energy requirement; compatible with standard microcontroller GPIO or optocoupler drivers without external amplification. |
| dIT/dt | 50 A/μs - Minimum required rate of anode current rise to avoid false turn-on; constrains snubber design in inductive switching. |
| tq | ≤50 μs - Circuit-commutated turn-off time at 125°C; sets minimum off-time between half-cycles in phase-control operation. |
Pinout & Package
Package: Resin-molded TO-220AB-compatible outline (17 mm × 12 mm × 4.7 mm max), 3-terminal, isolated tab (cathode-connected case). Standard weight: 2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Left) | Cathode | Main current return path; electrically connected to metal tab; must be isolated from heatsink unless referenced to system ground. |
| 2 (Center) | Anode | Main high-side current input; carries full load current; polarity-sensitive for AC phase control. |
| 3 (Right) | Gate | Control terminal; triggers conduction when forward-biased ≥1.5 V with ≥10 mA; sensitive to noise and dv/dt. |
Key Features
| Feature | Design Value |
|---|---|
| TO-220AB package compatibility | Enables drop-in replacement in legacy designs using standard TO-220 mounting hardware and PCB footprints. |
| High surge current rating | 80 A (50 Hz, 1-cycle sine) allows reliable startup into highly inductive or capacitive loads without failure. |
| Low gate trigger threshold | Guaranteed turn-on with ≤10 mA/1.5 V enables direct drive from logic-level sources, reducing BOM count. |
| Stable high-temperature operation | Specified performance maintained from −40°C to +125°C junction temperature; supports sealed or high-ambient environments. |
Applications
| Motor Speed Control | Temperature Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST402A | Same 400 V VDRM, but IT(AV) = 4 A; higher VTM (1.6 V); TO-220AC package (non-isolated tab). | Limited to lower-current loads; requires insulated mounting if cathode isolation needed. | Select when cost sensitivity outweighs current headroom and isolation requirements. |
| BT169G | Lower VDRM (400 V same), but IT(AV) = 0.8 A; TO-92 package; gate trigger current ≤15 mA. | Suitable only for signal-level triggering or pilot SCRs-not main power switching. | Use only as gate driver stage for larger SCRs like 5P4SMA(YK)-AZ; not a direct functional replacement. |
Compared with ST402A and BT169G, the 5P4SMA(YK)-AZ provides higher current capacity (5 A vs. 4 A or 0.8 A), lower conduction loss (1.4 V vs. 1.6 V), and isolated-tab packaging-making it uniquely suited for mains-powered industrial and appliance controls where thermal management and safety isolation are critical.

FAQ
What is the maximum repetitive peak off-state voltage rating for the 5P4SMA(YK)-AZ?
The 5P4SMA(YK)-AZ has a repetitive peak off-state voltage (VDRM) rating of 400 V and a repetitive peak reverse voltage (VRRM) of 400 V. These values define its ability to block AC line voltage during the non-conducting half-cycle. The device also supports non-repetitive peaks up to 500 V (VRSM/VDSM), accommodating short-duration surges without breakdown.
Does the 5P4SMA(YK)-AZ have an isolated tab, and how does that affect heatsinking?
Yes, the 5P4SMA(YK)-AZ features an isolated metal tab connected to the cathode terminal. This allows direct mounting to a grounded heatsink without electrical isolation hardware-reducing thermal resistance and simplifying mechanical design. However, system grounding must ensure the cathode potential remains referenced correctly to avoid unintended conduction paths.
What gate drive conditions are required to reliably trigger the 5P4SMA(YK)-AZ?
The 5P4SMA(YK)-AZ requires a gate trigger current (IGT) ≤10 mA and gate trigger voltage (VGT) ≤1.5 V under standard test conditions (VDM = 6 V, RL = 100 Ω, Tj = 25°C). At elevated temperatures (125°C), VGT may rise slightly, but remains within 1.5 V max. Pulse width should exceed 10 μs to ensure latch-up.
Can the 5P4SMA(YK)-AZ be used in 60 Hz AC applications?
Yes, the 5P4SMA(YK)-AZ is fully qualified for 60 Hz operation. Its surge on-state current rating is specified at 88 A for a 60 Hz sine half-wave (1 cycle), and all dynamic parameters-including tq (≤50 μs) and dv/dt (≥40 V/μs)-are validated at 125°C under 60 Hz conditions.
Is the 5P4SMA(YK)-AZ compliant with RoHS and lead-free assembly requirements?
Yes, the 5P4SMA(YK)-AZ meets EU RoHS Directive requirements. Renesas Electronics confirms compliance for this device in its official environmental documentation, supporting lead-free reflow soldering processes. No exemptions apply, and the device contains no restricted substances above threshold limits.
