Product details
Overview
ASSR-1510-003E from Broadcom is a single-channel, normally-off solid-state relay (Photo MOSFET) in 4-pin SO package, rated for 60 V output withstand voltage, 1.0 A DC output current, and 0.5 Ω max on-resistance at 25°C. It functions as an optically isolated SPST switch replacing electromechanical relays in industrial control signal routing.
For engineers reviewing the ASSR-1510-003E datasheet, pinout, applications, or equivalent options, key selection criteria include input LED drive compatibility (3 mA min turn-on), output leakage (<1 μA), fast switching (0.27 ms typical Ton), high transient immunity (>1 kV/μs), and UL 3750 Vrms isolation rating.
Technical Context
The ASSR-1510-003E 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 MOSFETs. Its single-pole, single-throw (SPST), Form A configuration provides galvanic isolation with 3750 Vrms input-output withstand voltage per UL1577.
It operates across –40°C to +85°C ambient temperature, requires only 3 mA minimum input current to activate, and turns off when input voltage drops to ≤0.8 V. Output characteristics are specified for DC-only loads with 1.0 A continuous current capability and 0.2 Ω typical R(ON) under pulsed conditions (≤30 ms).

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 | 60 V/1.0 A rating, 0.35 Ω RON, SO-6 package with integrated snubber; 0.35 ms Ton | Requires external RC snubber for inductive loads; higher pin count limits board density | Preferred where built-in transient suppression is needed for solenoid/valve drivers |
| Vishay VO1263BA | 60 V/1.2 A rating, 0.25 Ω RON, 4-pin SO package; 0.2 ms Ton; CSA/UL certified | Slightly higher current capacity but lower isolation voltage (3750 Vrms same); identical footprint | Drop-in replacement if higher current margin or faster switching is prioritized over Broadcom's broader regulatory approvals |
Compared with ASSR-1510-003E, TLP3558A adds integrated snubbing at the cost of larger package and slower switching, while VO1263BA offers marginally better RON and speed in the same SO-4 form factor but lacks CSA Component Acceptance Notice #5 certification.

FAQ
What is the maximum continuous output current rating for ASSR-1510-003E?
The ASSR-1510-003E supports up to 1.0 A continuous DC output current at 25°C ambient, with derating required above that temperature per Figure 1 in the datasheet. At 85°C ambient, the safe operating current reduces to approximately 0.7 A to maintain junction temperature below 125°C. This rating applies to DC-only loads using the standard connection topology shown for ASSR-1510 in the schematics section of the ASSR-1510-003E datasheet.
Does ASSR-1510-003E support AC load switching?
No, ASSR-1510-003E is rated exclusively for DC load switching. Its internal MOSFET structure and output specifications-including 60 V output withstand voltage and 1.0 A DC current rating-are defined for unidirectional current flow. For AC switching, engineers must select the ASSR-1511 variant, which supports both AC/DC and DC-only configurations with different pin assignments and on-resistance values.
What is the minimum input current required to reliably turn on ASSR-1510-003E across its full temperature range?
The ASSR-1510-003E requires a minimum input current of 3 mA to guarantee turn-on at all temperatures from –40°C to +85°C. While the device may activate at lower currents (e.g., ≥0.5 mA), Broadcom recommends operating at ≥5 mA to ensure robust performance across the full temperature and manufacturing tolerance range, as stated in the Recommended Operating Conditions table of the ASSR-1510-003E datasheet.
How does the on-resistance (RON) of ASSR-1510-003E vary with temperature?
The ASSR-1510-003E exhibits a positive temperature coefficient for on-resistance: RON increases from ~0.12 Ω at –40°C to ~0.5 Ω at +125°C junction temperature, as shown in Figure 9 of the ASSR-1510-003E datasheet. At 25°C ambient and 5 mA input current, typical RON is 0.2 Ω. Designers must account for this rise when calculating worst-case conduction losses and thermal design margins.
Is ASSR-1510-003E certified for use in medical or automotive applications?
No, ASSR-1510-003E is not certified for medical or automotive use. The datasheet explicitly states it is "not AEC-Q100 qualified and not recommended for automotive applications" and "not to be used in military or aerospace applications." While it meets UL1577 and CSA Component Acceptance Notice #5 for industrial safety, it lacks IEC 60601-1 medical certification and AEC-Q100 stress testing required for automotive deployment.
