Product details
Overview
ASSR-1411-501E from Broadcom is a single-channel, normally-off solid-state relay (Photo MOSFET) in a 300-mil DIP-6 gull wing surface-mount package, featuring 60 V output withstand voltage, 0.6 A/1.2 A dual-mode output current rating, and 0.2 Ω typical on-resistance for DC-only operation - used for replacing electromechanical relays in telecom switching and industrial control signal isolation.
For engineers reviewing the ASSR-1411-501E datasheet, pinout, applications, or equivalent options, key selection criteria include input LED drive compatibility (3 mA turn-on threshold), AC/DC vs. DC-only output configuration options, thermal derating behavior up to +85°C, and UL1577/CSA-certified 3750 Vrms input-output isolation.
Technical Context
The ASSR-1411-501E integrates an AlGaAs infrared LED optically coupled to a high-speed photovoltaic diode array and driver circuit that controls two discrete high-voltage MOSFETs. Its output stage supports two distinct connection modes: Connection A enables bidirectional AC/DC switching with 0.6 A/0.7 Ω R(ON); Connection B configures unidirectional DC-only operation delivering 1.2 A/0.2 Ω R(ON).
It operates across –40°C to +85°C ambient temperature, achieves 0.25 ms typical turn-on time and 0.04 ms typical turn-off time at 5 mA input current, and provides >1 kV/μs transient immunity with 3750 Vrms isolation rated per UL1577 for 1 minute.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Withstand Voltage | 60 V - maximum continuous voltage across output terminals before breakdown; requires external overvoltage protection in transient-prone applications |
| Output Current Rating | 0.6 A (AC/DC mode) / 1.2 A (DC-only mode) - defines safe load-handling capacity depending on output wiring configuration |
| On-Resistance R(ON) | 0.2 Ω typical (DC-only) / 0.7 Ω typical (AC/DC) - directly impacts conduction loss and thermal rise under load |
| Input Turn-On Threshold | 3 mA - minimum LED forward current required to reliably close the output switch across full temperature range |
| Isolation Voltage | 3750 Vrms for 1 min - certified dielectric strength enabling safety-critical signal isolation in medical and industrial systems |
| Switching Speed | 0.25 ms TON / 0.04 ms TOFF typical - enables high-frequency control of signals without mechanical wear or contact bounce |
| Operating Temperature | –40°C to +85°C - validated performance envelope for use in harsh industrial and telecom environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | LED Anode | Positive input terminal for infrared LED; requires series resistor to limit IF to 3–20 mA |
| Pin 2 | LED Cathode | Ground return path for LED; tied to system ground or low-side switch |
| Pin 3 | Output Source (S1) | High-side output terminal for Connection A (AC/DC) or positive DC output for Connection B |
| Pin 4 | Output Drain (D1) | Low-side output terminal for Connection A; common return for AC/DC loads |
| Pin 5 | Output Source (S2) | Unused in single-channel ASSR-1411; left unconnected or grounded per layout guidelines |
| Pin 6 | Output Drain (D2) | Unused in single-channel ASSR-1411; must remain unconnected to avoid leakage paths |
Key Features
| Feature | Design Value |
|---|---|
| Optically isolated SPST relay | Eliminates galvanic coupling between control and load circuits, enabling noise-immune signal routing in mixed-signal systems |

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), 0.2 ms TON - lower current capability and higher on-resistance than ASSR-1411-501E | Limited to low-power DC loads only; not rated for AC/DC bidirectional operation | Select when board space is constrained and load current remains ≤0.4 A with SO-6 footprint compatibility |
| Vishay VO3120 | DIP-6 through-hole package, 60 V/0.35 A rating, 0.5 Ω R(ON), 0.5 ms TON - slower switching and lower current handling | Suitable only for static DC switching; lacks DC-only mode optimization and thermal derating curves | Choose for legacy through-hole designs where surface-mount gull wing is not feasible and speed is non-critical |
Compared with TLP3545A and VO3120, the ASSR-1411-501E offers superior current capacity (1.2 A DC), lower on-resistance (0.2 Ω), faster switching (0.04 ms TOFF), and dual-mode flexibility - making it optimal for high-reliability, high-cycle-count industrial and telecom applications requiring both AC and DC load support.

FAQ
What is the minimum input current required to activate the ASSR-1411-501E?
The ASSR-1411-501E turns on with a minimum input current of 3 mA through its internal LED. While the device may respond at lower currents (≥0.5 mA), Broadcom specifies 3 mA as the guaranteed turn-on threshold across the full –40°C to +85°C operating temperature range. Operating at 5 mA is recommended for robust performance and margin against aging or temperature drift. This value is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the AV02-0241EN datasheet.
Can the ASSR-1411-501E switch AC loads, and what are the limitations?
Yes, the ASSR-1411-501E supports AC/DC loads using Connection A wiring (Pins 3 and 4), with a 60 V peak output withstand voltage and 0.6 A RMS current rating. It is not rated for continuous AC line voltage (e.g., 120/240 VAC) without external snubbing or overvoltage protection. The datasheet explicitly warns that overvoltage transients require external clamping circuits. Its AC capability is intended for low-voltage signal-level AC switching (e.g., audio, telecom tones) or controlled low-power AC loads within the 60 V/0.6 A envelope.
How does the DC-only Connection B configuration affect the ASSR-1411-501E's electrical performance?
In DC-only Connection B (using Pins 3, 4, and 6), the ASSR-1411-501E delivers 1.2 A output current and reduces typical on-resistance to 0.2 Ω - doubling current capacity and halving conduction loss versus AC/DC mode. This configuration disables bidirectional operation and requires unidirectional DC load polarity. Derating curves in Figure 3 confirm sustained 1.2 A operation up to +60°C ambient on a 4-layer board with 10 mA LED drive, making it ideal for high-efficiency DC power switching in industrial controls.
What safety certifications apply to the ASSR-1411-501E?
The ASSR-1411-501E is UL recognized per UL 1577 (3750 Vrms for 1 minute) and approved under CSA Component Acceptance Notice #5. It meets IEC/EN/DIN EN 60747-5-2 insulation requirements for reinforced isolation, with 7.1 mm minimum creepage and 4.9 mm minimum clearance between input and output terminals. These certifications validate its use in Class I and Class II medical equipment (BF-rated), industrial control panels, and telecom infrastructure where regulatory compliance is mandatory.
Is the ASSR-1411-501E suitable for automotive applications?
No, the ASSR-1411-501E is not qualified for automotive use. The datasheet explicitly states: "The components featured in this data sheet are not recommended to be used in military or aerospace applications or environments. The components are not AEC-Q100 qualified and not recommended for automotive applications." Its specified operating temperature range (–40°C to +85°C) falls short of AEC-Q100 Grade 2 (–40°C to +105°C) requirements, and it lacks automotive-specific qualification testing for vibration, ESD, and lifetime reliability.
