Product details
Overview
ASSR-1530-005E from Broadcom is a dual-channel, normally-off, solid-state SPST relay (Photo MOSFET) with 60 V output withstand voltage, 1.0 A DC output current rating, 0.5 Ω max on-resistance, and SO-8 surface-mount package. It functions as an optically isolated bidirectional signal switch for industrial control and data acquisition systems requiring high transient immunity and safety-rated isolation.
For engineers reviewing the ASSR-1530-005E datasheet, pinout, applications, or equivalent options, key selection criteria include input LED drive compatibility (3 mA min turn-on), dual-channel 1 Form A EMR equivalence, UL/CSA-certified 3750 Vrms isolation, and thermal derating behavior across –40°C to +85°C ambient.
Technical Context
The ASSR-1530-005E integrates an AlGaAs infrared LED input stage optically coupled to a high-voltage detector circuit comprising a photovoltaic diode array and driver that controls two discrete high-voltage MOSFETs. Its dual-channel architecture enables independent switching of two isolated loads using a single 4-pin input (pins 1–4) and 4-pin output (pins 5–8) configuration.
It operates with CMOS-compatible low input current (3 mA min for turn-on; ≤0.8 V for turn-off), delivers fast switching (0.27 ms typical Ton, 0.04 ms typical Toff at 5 mA), and maintains high input-output transient immunity (>1 kV/μs dVI-O/dt). All electrical specs are guaranteed over –40°C to +85°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Withstand Voltage | 60 V - Maximum continuous voltage the output terminals can block without breakdown; defines safe operating range for AC/DC load switching. |
| Max Output Current | 1.0 A - Rated DC current per channel at TA = 25°C; derates with ambient temperature per Figure 4. |
| On-Resistance | 0.5 Ω max - Total channel resistance when fully on; determines I²R power loss and voltage drop under load. |
| Turn-On Time | 0.27 ms typ - Time from 10% to 90% of output current rise; critical for high-speed sequencing in automation. |
| Isolation Voltage | 3750 Vrms - Input-to-output dielectric withstand rating per UL1577 for 1 minute; satisfies reinforced insulation requirements. |
| Input Threshold | 3 mA min - Minimum forward current required to reliably activate both channels; ensures compatibility with standard logic drivers. |
| Operating Temp | –40°C to +85°C - Ambient temperature range over which all parameters are guaranteed; supports industrial-grade deployment. |
Pinout & Package
ASSR-1530-005E uses an 8-pin SOIC (SO-8) surface-mount package with gull-wing leads, 2.54 mm pitch, and 6.81 mm × 4.40 mm body dimensions. Pin 1 is marked with a dot; pins 1–4 form the input LED anode/cathode pair per channel; pins 5–8 are the output source/drain terminals for two independent MOSFET switches.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | LED Anode / Cathode (Ch. 1) | Optical input for Channel 1; requires ≥3 mA forward current to activate corresponding output. |
| 3, 4 | LED Anode / Cathode (Ch. 2) | Optical input for Channel 2; electrically isolated from Ch. 1; enables independent control. |
| 5, 6 | Output Drain / Source (Ch. 1) | Bidirectional output terminals for Channel 1; rated for 60 V blocking and 1.0 A conduction. |
| 7, 8 | Output Drain / Source (Ch. 2) | Bidirectional output terminals for Channel 2; identical ratings and isolation to Ch. 1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual SPST relay replacement | Two independent 1 Form A solid-state switches in one SO-8 package-replaces two electromechanical relays with no moving parts. |
| High-speed switching | 0.27 ms typical turn-on and 0.04 ms typical turn-off-enables precise timing control in PLC I/O modules and test equipment. |

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 0.7 Ω R(ON) max and slower 0.5 ms Ton. | Limited to lower-speed switching; less suitable for sub-millisecond timing-critical interlocks. | Choose when cost sensitivity outweighs speed and on-resistance requirements. |
| Vishay VO3120 | Dual-channel, 60 V/1.2 A, DIP-8 package; higher current rating but through-hole only and 0.6 Ω R(ON) max. | Requires PCB rework for surface-mount designs; larger footprint reduces board density. | Prefer for legacy through-hole systems needing marginally higher current headroom. |
Compared with TLP3558A and VO3120, the ASSR-1530-005E offers the lowest combination of on-resistance (0.5 Ω max) and turn-on time (0.27 ms typ) in an SO-8 package, making it optimal for space-constrained, high-speed industrial I/O where thermal efficiency and timing precision are prioritized.

FAQ
What is the maximum output current rating for ASSR-1530-005E at 85°C ambient?
The ASSR-1530-005E supports up to 0.8 A per channel at TA = 85°C, as shown in Figure 4 of the AV02-0036EN datasheet. This derating ensures junction temperature remains below 125°C under continuous DC load; for pulsed operation (≤30 ms), 1.0 A remains valid if average power stays within 700 mW limit.
Does ASSR-1530-005E support AC load switching?
Yes, the ASSR-1530-005E supports bidirectional AC/DC switching with 60 V peak output withstand voltage and 1.0 A RMS current rating per channel. Its Photo MOSFET architecture enables zero-crossing–free switching, but external snubbers may be needed for inductive AC loads to suppress voltage transients.
What is the input-to-output capacitance of ASSR-1530-005E?
The ASSR-1530-005E has a typical input-output capacitance of 0.8 pF at 1 MHz and 0 Vdc bias, as specified in the Package Characteristics table (page 9 of AV02-0036EN). This ultra-low value minimizes capacitive coupling noise in high-impedance or precision analog isolation applications.
Can ASSR-1530-005E replace two separate ASSR-1510 relays?
Yes, the ASSR-1530-005E provides two independent SPST channels in one SO-8 package, functionally equivalent to two ASSR-1510 units. However, its shared thermal mass means simultaneous full-load operation of both channels requires adherence to the dual-channel derating curve in Figure 4-not the single-channel curve.
Is ASSR-1530-005E qualified for automotive applications?
No, the ASSR-1530-005E is not AEC-Q100 qualified and is explicitly not recommended for automotive use per the datasheet caution note. It is rated for industrial temperature range (–40°C to +85°C) and lacks automotive-specific reliability testing, qualification, or packaging enhancements.
