Product details
Overview
The ASSR-1530-505E from Broadcom is a dual-channel, normally-off, solid-state SPST relay (Photo MOSFET) with optically isolated input and high-voltage MOSFET output stage. It delivers 1.0 A DC output current, 60 V output withstand voltage, and 0.2 Ω typical on-resistance at 25°C - designed for industrial control and factory automation signal switching where electromechanical relay replacement is required.
For engineers reviewing the ASSR-1530-505E datasheet, pinout, applications, or equivalent options, key selection criteria include its SO-8 surface-mount package, 3750 Vrms input-output isolation, 0.27 ms typical turn-on time, and dual-channel 2 Form A relay functionality compatible with CMOS-level input drive.
Technical Context
The ASSR-1530-505E integrates an AlGaAs infrared LED optically coupled to a photovoltaic diode array and driver circuit that controls two discrete high-voltage MOSFETs. Its dual-channel architecture provides independent SPST switching paths, each rated for 60 V output withstand and 1.0 A continuous current under derated conditions.
It operates across –40°C to +85°C ambient temperature, requires only 3 mA minimum input LED current to activate, and turns off when input voltage drops to ≤0.8 V. Input-output insulation meets UL1577 (3750 Vrms/1 min) and CSA Component Acceptance Notice #5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Toshiba TLP3558A | Dual-channel, 60 V/1.0 A, SO-8, but uses GaAs LED and has higher RON (0.3 Ω typ) | Slightly slower tON (0.35 ms) and lower dV/dt immunity (0.8 kV/μs) | Acceptable where marginally higher conduction loss and reduced noise immunity are tolerable |
| Vishay VO3120 | Dual-channel, 60 V/0.75 A, DIP-8, higher RON (0.35 Ω), no RoHS-compliant tape-and-reel option listed | Larger through-hole footprint; limited to 0.75 A continuous output | Only suitable if legacy DIP layout is fixed and lower current rating is acceptable |
Compared with TLP3558A and VO3120, the ASSR-1530-505E offers superior combination of low on-resistance (0.2 Ω), fast switching (0.27 ms), and full RoHS-compliant surface-mount packaging - making it optimal for space-constrained, high-reliability industrial PCBs requiring dual SPST isolation.

FAQ
What is the maximum continuous output current rating for the ASSR-1530-505E?
The ASSR-1530-505E supports up to 1.0 A continuous output current per channel at TA = 25°C with appropriate PCB copper area for heat dissipation. Derating applies above 25°C - e.g., ~0.8 A at 60°C ambient - as shown in Figure 4 of the AV02-0036EN datasheet. This rating assumes pulsed operation or adequate thermal management to keep junction temperature below 125°C.
Does the ASSR-1530-505E support AC load switching?
No, the ASSR-1530-505E is rated for DC-only operation. Its output structure consists of two N-channel MOSFETs configured as single-pole, single-throw (SPST) switches with unidirectional conduction. For AC switching, use the ASSR-1511 variant, which supports bidirectional AC/DC connections via specific pin configurations.
What is the input LED forward voltage specification for the ASSR-1530-505E?
The ASSR-1530-505E has a typical forward voltage of 1.3 V at IF = 5 mA, with a guaranteed range of 1.1 V to 1.65 V across temperature and process variation. This low VF enables direct drive from 3.3 V or 5 V logic outputs with minimal series resistance - for example, a 330 Ω resistor suffices for 5 V supply and 5 mA drive.
How is isolation verified for the ASSR-1530-505E, and what safety standards does it meet?
The ASSR-1530-505E is UL recognized to 3750 Vrms for 1 minute per UL1577 and approved under CSA Component Acceptance Notice #5. Its isolation barrier is validated via dielectric withstand testing, with minimum clearance (4.9 mm) and creepage (4.8 mm) distances specified between input and output terminals. These values satisfy reinforced insulation requirements for industrial equipment operating up to 300 V RMS.
Can the ASSR-1530-505E be used in automotive applications?
No - the ASSR-1530-505E is explicitly not AEC-Q100 qualified and is not recommended for automotive use. The datasheet cautions against deployment in military, aerospace, or automotive environments due to lack of qualification for extended temperature cycling, vibration, and ESD robustness required by automotive standards. Industrial and medical applications remain its validated use cases.
