Product details
Overview
ASSR-4119-501E 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 400 V output withstand voltage, 0.1 A AC/DC current rating (0.2 A DC-only), 25 Ω typical on-resistance (8 Ω in DC-only mode), and 3750 VRMS input-output isolation. It replaces electromechanical relays in telecom switching and industrial control circuits requiring zero-crossing-free, bounce-free signal switching.
For engineers reviewing the ASSR-4119-501E datasheet, pinout, applications, or equivalent options, this device supports design decisions involving high-voltage isolation, low-input-current CMOS drive compatibility, bidirectional AC/DC load control, and RoHS-compliant surface-mount relay replacement with validated UL1577 and CSA safety approvals.
Technical Context
The ASSR-4119-501E integrates an AlGaAs infrared LED optically coupled to a photovoltaic diode array and dual-MOSFET driver circuit, enabling contact closure at ≥3 mA LED forward current and opening at ≤0.8 V LED voltage. Its output stage supports both AC/DC and DC-only configurations via external connection selection (A or B), directly determining R(ON) and IO ratings.
Input-to-output insulation meets UL1577 (3750 VRMS, 1 min) and CSA Component Acceptance Notice #5, with minimum creepage (7.4 mm) and clearance (7.1 mm) distances. The gull-wing DIP-6 package enables reflow-compatible surface mounting while maintaining mechanical and electrical equivalence to 1 Form A EMRs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Withstand Voltage | 400 V - Maximum continuous voltage across output terminals before breakdown; requires external overvoltage protection for transients. |
| Max Output Current (AC/DC) | 0.1 A - Sustained load current capability under standard operating conditions (TA = 25°C, pulse ≤30 ms). |
| Max Output Current (DC-only) | 0.2 A - Achieved only with Connection B wiring; enables higher-power DC loads without derating. |
| On-Resistance (AC/DC) | 25 Ω typical - Determines I²R power loss and voltage drop at 100 mA; impacts thermal design in continuous operation. |
| On-Resistance (DC-only) | 8 Ω typical - Measured at 200 mA pulse; reduces conduction loss by >65% vs AC/DC mode for DC solenoids or valves. |
| Input-Output Isolation | 3750 VRMS - Validated dielectric strength for 1 minute; satisfies reinforced insulation requirements per UL1577. |
| Turn-On / Turn-Off Time | 0.7 / 0.04 ms typical - Enables fast digital control of AC line switching without zero-crossing circuitry. |
Pinout & Package
The ASSR-4119-501E uses a 300-mil DIP-6 gull-wing surface-mount package with 2.54 mm lead pitch and 7.62 mm body width, optimized for automated placement and lead-free reflow (peak 260°C, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | LED Anode | Positive input for infrared LED; requires ≥3 mA forward current to activate relay. |
| Pin 2 | LED Cathode | Ground return for LED; logic-low (<0.8 V) deactivates output switch. |
| Pin 3 | LED Cathode (tie) | Internally connected to Pin 2; used for PCB layout symmetry and thermal relief. |
| Pin 4 | Output Source (S1) | High-side output terminal; connects to load in Connection A or B configurations. |
| Pin 5 | Output Drain (D1) | Low-side output terminal; completes load path; bidirectional conduction supported. |
| Pin 6 | Output Source (S2) | Internally tied to Pin 4; provides redundant bonding and current-sharing capability. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-compatible input | Operates with ≥3 mA LED current - eliminates need for external driver transistors in microcontroller GPIO interfaces. |
| Configurable output mode | Connection A (AC/DC) or B (DC-only) - selects between 0.1 A/25 Ω or 0.2 A/8 Ω operation without component change. |
| Reinforced safety isolation | 3750 VRMS @ 1 min, 7.4 mm creepage - meets end-equipment requirements for medical and industrial mains-connected systems. |
| Bidirectional output conduction | Supports AC and DC loads - enables use in both telecom line switching and DC valve control without polarity constraints. |
| Gull-wing SMT package | 300-mil DIP-6 footprint - maintains legacy DIP layout compatibility while enabling automated assembly and improved thermal performance vs through-hole. |

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 TLP3547 | 6-pin DIP, 400 V/0.1 A, 3750 VRMS isolation, but uses phototriac output (not MOSFET); higher R(ON) (35 Ω typical). | Optimized for AC-only loads; unsuitable for DC solenoids due to lack of DC hold capability. | Select when driving purely AC lighting or motor loads where zero-crossing switching is acceptable. |
| Vishay VO3120 | 6-pin DIP, 400 V/0.12 A, 5000 VRMS isolation, but requires 5 mA min. LED current and lacks DC-only configuration option. | Higher isolation rating suits harsher industrial environments; no R(ON) reduction mode for DC loads. | Prefer when maximum input-output withstand voltage is critical and DC load current remains ≤0.12 A. |
Compared with TLP3547 and VO3120, the ASSR-4119-501E uniquely supports configurable DC-only operation (0.2 A/8 Ω), offers lower drive current threshold (3 mA), and maintains identical DIP-6 gull-wing footprint-enabling direct layout reuse while expanding load flexibility.

FAQ
What is the minimum input current required to turn on the ASSR-4119-501E?
The ASSR-4119-501E 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 mA as the guaranteed turn-on threshold across the full operating temperature range (–40°C to +85°C). Operating at 5 mA ensures robust performance and aligns with recommended conditions in the AV02-0218EN datasheet.
How does the ASSR-4119-501E differ from the ASSR-4119-001E?
The ASSR-4119-501E and ASSR-4119-001E share identical electrical specifications and internal die, but differ in packaging and delivery format: the -501E variant uses tape-and-reel packaging with gull-wing surface-mount leads and is RoHS compliant, whereas the -001E uses tube packaging with through-hole leads. Both are 300-mil DIP-6 packages, but only the -501E is qualified for automated SMT assembly per the specified lead-free reflow profile.
Can the ASSR-4119-501E switch AC and DC loads simultaneously?
No-the ASSR-4119-501E supports either AC/DC loads (Connection A) or DC-only loads (Connection B), but not both simultaneously. Connection A configures the output for bidirectional conduction (0.1 A, 25 Ω), while Connection B ties internal nodes to enable unidirectional DC operation (0.2 A, 8 Ω). Mixing AC and DC paths violates the internal MOSFET biasing and risks latch-up or premature failure.
What safety certifications apply to the ASSR-4119-501E?
The ASSR-4119-501E is UL recognized per UL 1577 (3750 VRMS, 1 minute) and approved under CSA Component Acceptance Notice #5. It achieves insulation group IIIa and CTI rating of 175 V per DIN IEC 112, with 7.4 mm creepage and 7.1 mm clearance. These certifications are valid for the entire ASSR-4119 family, including the ASSR-4119-501E, and are documented in Broadcom's AV02-0218EN datasheet.
Is thermal derating required for continuous DC operation of the ASSR-4119-501E?
Yes-continuous DC operation of the ASSR-4119-501E requires thermal derating based on ambient temperature and PCB copper area. Figure 3 in the AV02-0218EN datasheet shows maximum allowable output current drops from 0.2 A at 25°C to ~0.12 A at 85°C for DC-only (Connection B) mode. Derating ensures junction temperature stays below 125°C; exceeding limits causes R(ON) increase and accelerated parametric drift.
