Product details
Overview
ASSR-1611-001E from Broadcom is a high-current, single-pole normally-open solid-state relay (MOSFET-based) designed as a drop-in replacement for electromechanical relays in industrial control systems. It features 60 V output withstand voltage, 2.5 A AC/DC load current rating, 65 mΩ typical on-resistance (Connection A), and operates across –40°C to +85°C. It switches loads using optically isolated input LED control with 5 mA minimum turn-on current.
For engineers reviewing the ASSR-1611-001E datasheet, pinout, applications, or equivalent options, this device is selected for high-reliability, high-speed switching in factory automation, data acquisition, and medical instrumentation where low leakage (<0.1 µA), fast turn-off (0.1 ms typ.), and 3750 Vrms input-output isolation are critical design requirements.
Technical Context
The ASSR-1611-001E 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 connection modes-Connection A (AC/DC capable, 65 mΩ RON) and Connection B (DC-only, 20 mΩ RON)-enable flexible system-level implementation while maintaining galvanic isolation.
It delivers high transient immunity (>1 kV/µs dV/dt), meets UL1577 (3750 Vrms/1 min) and CSA Component Acceptance safety standards, and supports CMOS-compatible input drive with 0.8 V maximum turn-off voltage. All electrical specifications are fully characterized 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 switching in industrial power circuits. |
| Max Output Current (Connection A) | 2.5 A - Rated continuous load current for AC or DC operation at TA = 25°C; derates linearly above 25°C per Figure 1. |
| On-Resistance (Connection A) | 65 mΩ typical - Low conduction loss enabling <165 mW power dissipation at 2.5 A; minimizes thermal rise in compact PCB layouts. |
| Turn-On / Turn-Off Time | 3.2 ms / 0.1 ms typical - Enables high-cycle-rate control (e.g., PWM-driven solenoids or motor brakes) without mechanical wear or contact bounce. |
| Input-Output Isolation Voltage | 3750 Vrms (1 min) - Certified dielectric strength ensuring safety compliance in Class I equipment and reinforced insulation designs. |
| Input Control Threshold | 5 mA min. turn-on / ≤0.8 V turn-off - Compatible with standard logic outputs (e.g., MCU GPIO, PLC drivers) without external level-shifting. |
| Output Leakage Current | 0.01 µA typical at 60 V - Ensures minimal standby power loss and signal integrity in high-impedance sensing or precision measurement paths. |
Pinout & Package
ASSR-1611-001E uses a 300-mil 6-pin DIP package with gull-wing surface-mount leads. Pin numbering follows standard DIP orientation with pin 1 marked by dot. The package provides 7.1 mm minimum clearance and 7.4 mm creepage between input and output sides per UL/CSA requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (LED input) | Positive terminal of internal infrared LED; requires series resistor to limit IF to 5–20 mA for reliable turn-on. |
| Pin 2 | Cathode (LED input) | Ground return for LED input; connects to system GND or logic low to complete input circuit. |
| Pin 3 | No Connect (NC) | Internally unconnected; must remain floating-no routing or soldering permitted. |
| Pin 4 | Output Source (Load side) | High-side output terminal for Connection A (AC/DC) or Connection B (DC-only); ties to load positive or high-side switch node. |
| Pin 5 | Output Drain (Load side) | Low-side output terminal; connects to load return path or system ground in low-side switching configurations. |
| Pin 6 | No Connect (NC) | Internally unconnected; must remain floating-no routing or soldering permitted. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VO1263AAC | 60 V/1.5 A rating, 100 mΩ RON, 5000 Vrms isolation, DIP-6 package | Lower current capacity and higher on-resistance limit use to low-power signal switching-not suitable for 2.5 A industrial loads. | Select when highest isolation voltage (5000 Vrms) is prioritized over load current capability and on-resistance. |
| Toshiba TLP3547 | 60 V/2.0 A rating, 80 mΩ RON, 5000 Vrms isolation, SO-6 package | SO-6 footprint requires PCB redesign; lower current rating restricts use in high-dynamic-load scenarios like motor braking. | Choose for space-constrained designs needing 5000 Vrms isolation, accepting reduced current headroom and different package geometry. |
Compared with VO1263AAC and TLP3547, the ASSR-1611-001E uniquely balances 2.5 A AC/DC load handling, 65 mΩ low on-resistance, and industry-standard DIP-6 gull-wing packaging-making it optimal for retrofitting legacy EMR-based industrial controllers without layout changes.

FAQ
What is the maximum continuous output current rating for ASSR-1611-001E under AC/DC operation?
The ASSR-1611-001E supports up to 2.5 A continuous output current in AC/DC Connection A mode at 25°C ambient temperature. This rating decreases linearly with rising temperature per Figure 1 in the datasheet; at 85°C, the derated current is approximately 1.7 A. The device must be mounted on a 4-layer PCB with adequate copper area to maintain thermal performance.
Does ASSR-1611-001E support both AC and DC loads, and how does connection configuration affect performance?
Yes, ASSR-1611-001E supports both AC and DC loads in Connection A mode (pins 4 and 5), with 65 mΩ typical on-resistance. In Connection B mode (pins 4 and 6), it supports DC loads only but achieves 20 mΩ typical on-resistance-reducing conduction loss by more than 69%. Pin 6 is internally connected to the MOSFET source, enabling lower RON but eliminating AC compatibility.
What safety certifications apply to ASSR-1611-001E, and what do they cover?
The ASSR-1611-001E is UL Recognized per UL1577 (3750 Vrms/1 minute) and approved under CSA Component Acceptance Notice #5. These certifications validate its input-output insulation integrity, including 7.1 mm clearance and 7.4 mm creepage distances. It is not rated for automotive (AEC-Q100) or aerospace use, and the 5000 Vrms option requires X21 variant ordering.
Can ASSR-1611-001E replace traditional electromechanical relays without PCB modifications?
Yes, ASSR-1611-001E uses a standard 300-mil 6-pin DIP gull-wing package identical to many legacy EMRs, enabling direct drop-in replacement. Its pinout matches common 1 Form A relay footprints (pins 1–2 = coil, pins 4–5 = NO contact), and its 5 mA input threshold is compatible with existing 5 V or 3.3 V logic drivers-no layout or schematic changes required.
What is the typical turn-off time of ASSR-1611-001E, and why is it critical in safety-critical applications?
The ASSR-1611-001E has a typical turn-off time of 0.1 ms at 25°C, with a maximum of 0.5 ms across –40°C to +85°C. This rapid deactivation is essential in safety-critical applications such as emergency stop circuits or defibrillator discharge control, where sub-millisecond response prevents hazardous energy buildup and ensures compliance with ISO 13849-1 and IEC 61508 timing requirements.
