Product details

Overview

PS7160L-1A-A from Renesas Electronics is a 1-channel normally open solid-state relay with GaAs LED input and MOS FET output, rated for 600 V breakdown voltage, 90 mA continuous load current (Connection A), 50 Ω typical on-state resistance at 10 mA, and 1.5 ms maximum turn-on time. It enables analog signal control in measurement and FA/OA equipment with low offset voltage and high linearity.

For engineers reviewing the PS7160L-1A-A datasheet, PS7160L-1A-A pinout, PS7160L-1A-A application, or PS7160L-1A-A equivalent, this page delivers verified specifications, safety-certified isolation performance (1500 V_r.m.s.), Pb-free surface-mount packaging, and real-world switching behavior under AC/DC load configurations.

Technical Context

The PS7160L-1A-A integrates an infrared GaAs LED coupled optically to a pair of back-to-back N-channel MOS FETs, enabling bidirectional AC/DC switching without external polarity management. Its output stage supports three distinct load connection topologies (A/B/C) to optimize current handling up to 210 mA under pulsed conditions.

Isolation is achieved via internal dielectric barrier rated at 1500 V_r.m.s. for 1 minute, with input-output capacitance limited to 1.1 pF and isolation resistance exceeding 10⁹ Ω at 1 kV_DC. The device operates across −40°C to +85°C ambient and requires ≤2 mA LED forward current for reliable turn-on.

Key Specifications

Parameter	Value and Actual Design Meaning
Breakdown Voltage	600 V - Withstands transient overvoltage up to 600 V across output terminals without breakdown.
Continuous Load Current	90 mA (Connection A) - Sustains 90 mA DC or RMS AC load current with thermal stability in standard PCB layouts.
On-state Resistance	42–50 Ω - Ensures minimal I²R loss and voltage drop (<0.9 V at 20 mA) in analog signal path applications.
Turn-on/Off Time	0.8–1.5 ms / 0.06–0.2 ms - Enables precise timing control in automated test equipment and programmable logic interfaces.
Isolation Voltage	1500 V_r.m.s. - Meets UL, BSI, and CSA safety standards for reinforced insulation between input and output circuits.
LED Operating Current	2–20 mA - Activates reliably with microcontroller GPIO outputs without external driver circuitry.
Output Capacitance	110 pF - Minimizes capacitive coupling noise in high-impedance analog sampling paths.

Pinout & Package

PS7160L-1A-A uses a 6-pin surface-mount DIP package (SMD-DIP) with gull-wing leads, compatible with standard IR reflow profiles (peak 260°C, ≤10 s). Pin 1 is LED anode; pins 4 and 6 are MOS FET drains; pin 5 is source; pin 3 is NC.

Pin/Terminal	Circuit Role	Design Meaning
1	LED Anode	Positive input terminal for GaAs LED; requires series resistor to limit IF to 2–20 mA.
2	LED Cathode	Ground return for input side; connects to MCU or logic ground.
3	No Connect (NC)	Internally unconnected; must remain floating or tied to GND per layout best practice.
4	MOS FET Drain	One output terminal for bidirectional AC/DC switching; used in Connection A/B/C topologies.
5	MOS FET Source	Common output node; referenced to load return path in all connection modes.
6	MOS FET Drain	Second output terminal; paired with Pin 4 to form back-to-back FET structure for AC conduction.

Key Features

Feature	Design Value
Low LED drive requirement	2 mA minimum turn-on current enables direct interface with 3.3 V/5 V microcontrollers without buffer stages.
High linearity & low offset	Supports precision analog signal routing (e.g., sensor multiplexing) with minimal distortion or DC shift.
Pb-free surface-mount construction	Complies with RoHS Directive; qualified for IR reflow (260°C peak, ≤10 s) and wave soldering.
Triple safety certification	UL E72422, BSI 8245/8246, and CSA CA 101391 approvals validate isolation integrity for industrial end-equipment.
AC/DC load flexibility	Three defined connection modes (A/B/C) allow optimization for current rating, voltage polarity, and thermal distribution.

Equivalent & Alternatives

The following parts are listed as comparable options for similar solid-state relay applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLP3554(TP,E	Higher 1.2 A load current rating; TO-263-4L package; 1.2 ms max ton; 600 V V_DSS.	Targeted at higher-power industrial loads; requires larger PCB footprint and heatsinking.	Select when >200 mA continuous load or faster switching (<1.2 ms) is required; verify layout compatibility with TO-263.
PS7141-1A-A	Same 6-pin DIP package; lower 400 V breakdown; 60 mA continuous load; 100 Ω typical Ron.	Optimized for cost-sensitive, lower-voltage control applications (e.g., consumer OA).	Choose for 400 V systems where reduced isolation margin and higher Ron are acceptable trade-offs for lower BOM cost.

Compared with TLP3554(TP,E and PS7141-1A-A, the PS7160L-1A-A uniquely balances 600 V robustness, 90 mA load capacity, and 50 Ω Ron in a compact SMD-DIP-making it optimal for space-constrained, medium-voltage analog switching where safety certification and linearity are mandatory.

FAQ

What is the maximum continuous load current rating for PS7160L-1A-A under Connection A configuration?

The PS7160L-1A-A supports a maximum continuous load current of 90 mA under Connection A (IL = 90 mA), as specified in the Absolute Maximum Ratings table with IF ≥ 2 mA. This rating applies at TA = 25°C and assumes proper PCB thermal design; derating is required above 25°C per the Maximum Load Current vs. Ambient Temperature curve.

Does PS7160L-1A-A support AC load switching, and if so, how is it implemented?

Yes, PS7160L-1A-A supports AC load switching via its dual-drain MOS FET output structure (pins 4 and 6) and common source (pin 5). The datasheet defines Connection C specifically for AC operation, enabling bidirectional conduction without external diodes or H-bridge circuitry-making PS7160L-1A-A suitable for AC solenoid and lamp control in industrial panels.

What safety certifications does PS7160L-1A-A hold, and what do they cover?

PS7160L-1A-A holds UL File No. E72422, BSI Nos. 8245/8246, and CSA No. CA 101391. These certifications validate its 1500 V_r.m.s. input-output isolation barrier for 1 minute, confirming compliance with reinforced insulation requirements for industrial and medical (non-life-support) end-equipment per IEC/EN 60747-5-2.

Can PS7160L-1A-A be used with 3.3 V microcontroller GPIOs without additional driver circuitry?

Yes, PS7160L-1A-A can be driven directly by 3.3 V microcontroller GPIOs: its recommended LED operating current starts at just 2 mA (IF = 2 mA), and forward voltage is 1.2–1.4 V at 10 mA. A simple 1 kΩ series resistor limits current to ~2.2 mA at 3.3 V, ensuring reliable turn-on without buffer transistors or level shifters.

What is the thermal derating behavior of PS7160L-1A-A above 25°C ambient temperature?

PS7160L-1A-A exhibits linear thermal derating above 25°C: its maximum load current decreases from 90 mA at 25°C to zero at 85°C, following the curve in Figure 5 of the datasheet. At 60°C ambient, the usable continuous load current drops to approximately 55 mA for Connection A-requiring careful thermal design in enclosed or high-temperature environments.
