Product details
Overview
ASSR-1410-503E from Broadcom is a single-channel, normally-off solid-state relay (Photo MOSFET) with optically isolated AlGaAs LED input and dual high-voltage MOSFET output stage. It provides 60 V output withstand voltage, 0.6 A DC current rating, 0.2 Ω typical on-resistance (DC), 0.25 ms typical turn-on time, and 3750 Vrms input-output isolation - designed for replacing electromechanical relays in telecom signal switching and industrial control interfaces.
For engineers reviewing the ASSR-1410-503E datasheet, pinout, applications, or equivalent options, key selection criteria include its SO-4 gull-wing surface-mount package, CMOS-compatible 3 mA turn-on threshold, low 0.4 pF input-output capacitance, and UL1577/CSA safety certification for reinforced insulation in safety-critical signal routing.
Technical Context
The ASSR-1410-503E implements a photovoltaic diode array coupled to driver circuitry that directly controls two discrete high-voltage MOSFETs - enabling true bidirectional AC/DC switching without external bias. Its optical coupling eliminates galvanic paths while delivering fast, bounce-free operation with no moving parts.
It operates across –40°C to +85°C ambient temperature, requires only 3 mA minimum LED forward current to activate, and turns off fully at ≤0.8 V input voltage. The device's internal structure ensures <1 μA output leakage at 60 V and maintains stable R(ON) performance under pulsed load conditions up to 30 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Withstand Voltage | 60 V - maximum continuous voltage the output contacts can block without breakdown, critical for safe AC line-level signal isolation. |
| Max Output Current (DC) | 0.6 A - rated continuous current capacity at TA = 25°C; derates above 40°C per Figure 1. |
| Typical On-Resistance | 0.2 Ω - low conduction loss enabling efficient low-power switching with minimal I²R heating. |
| Turn-On / Turn-Off Time | 0.25 ms / 0.04 ms - enables high-speed digital control of analog signals without timing jitter or contact wear. |
| Input-Output Isolation | 3750 Vrms - meets UL1577 and CSA Component Acceptance #5 for reinforced insulation in medical and industrial equipment. |
| Input Forward Voltage | 1.3 V typ. @ 5 mA - compatible with standard 3.3 V and 5 V logic outputs without series resistor recalculations. |
| Input-Output Capacitance | 0.4 pF - ultra-low coupling capacitance minimizes high-frequency noise injection between isolated domains. |
Pinout & Package
ASSR-1410-503E uses a 4-pin Small Outline (SO-4) gull-wing surface-mount package with 1.27 mm pitch, RoHS-compliant lead finish, and JEDEC-standard reflow profile compatibility.

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 TLP3545A | SO-6 package; 60 V/0.4 A rating; 0.35 Ω R(ON); 0.5 ms TON; 3750 Vrms isolation. | Limited to lower current loads; higher on-resistance increases thermal stress in sustained 0.6 A operation. | Choose when board layout accommodates SO-6 and peak load current stays below 0.4 A. |
| Vishay VO1263BA | DIP-4 package; 60 V/0.35 A rating; 0.5 Ω R(ON); 0.4 ms TON; 5000 Vrms isolation. | Through-hole mounting only; lower current rating and higher R(ON) reduce efficiency in high-duty-cycle use. | Select for legacy through-hole designs where 5000 Vrms isolation outweighs current capability trade-offs. |
Compared with TLP3545A and VO1263BA, the ASSR-1410-503E delivers superior current handling (0.6 A vs. ≤0.4 A), lowest on-resistance (0.2 Ω), and surface-mount gull-wing packaging optimized for automated assembly - making it the preferred choice for space-constrained, high-reliability signal switching in modern industrial and medical platforms.

FAQ
What is the minimum input current required to turn on the ASSR-1410-503E?
The ASSR-1410-503E turns on with a minimum input current of 3 mA through its AlGaAs LED input stage. While the device may activate at lower currents (≥0.5 mA), Broadcom specifies 3–20 mA as the recommended operating range to ensure reliable switching across –40°C to +85°C ambient temperatures. This makes the ASSR-1410-503E compatible with standard CMOS logic outputs without additional driver circuitry.
Does the ASSR-1410-503E support AC load switching?
Yes, the ASSR-1410-503E supports bidirectional AC/DC switching due to its dual-MOSFET output configuration. Its 60 V output withstand voltage applies to both polarities, and its 0.2 Ω typical on-resistance ensures low conduction loss for low-power AC signals (e.g., audio, telecom line signaling). However, it is not rated for mains-voltage AC loads - use only within its specified 60 V, 0.6 A DC or AC peak limits.
What safety certifications does the ASSR-1410-503E hold?
The ASSR-1410-503E is UL recognized per UL 1577 (3750 Vrms for 1 minute) and approved under CSA Component Acceptance Notice #5. These certifications validate its reinforced insulation barrier for use in medical (BF-rated), industrial, and telecom equipment. It is not AEC-Q100 qualified and is explicitly not recommended for automotive applications per Broadcom's datasheet caution notice.
How does the ASSR-1410-503E compare to electromechanical relays in terms of lifetime?
The ASSR-1410-503E offers significantly longer operational life than electromechanical relays - exceeding 10⁹ cycles versus typical EMR ratings of 10⁵–10⁷ cycles - because it has no moving parts or contact erosion. Its solid-state construction eliminates bounce, arcing, and coil wear, making the ASSR-1410-503E ideal for high-frequency switching applications such as data multiplexing and programmable logic control where reliability and maintenance-free operation are essential.
Can the ASSR-1410-503E be used in high-noise industrial environments?
Yes, the ASSR-1410-503E is specifically designed for high-noise environments, featuring >1 kV/μs output transient rejection and >10 kV/μs input-output transient immunity. Its optical isolation architecture inherently rejects common-mode noise, and its low 0.4 pF input-output capacitance prevents high-frequency coupling. These characteristics make the ASSR-1410-503E suitable for PLC I/O modules, motor drives, and factory automation systems subject to EFT, surge, and radiated emissions.
