Product details
Overview
ASSR-1219-001E from Broadcom is a single-channel, normally-off solid-state relay (Photo MOSFET) in a 6-pin DIP through-hole package, featuring optically isolated AlGaAs LED input and dual high-voltage MOSFET output stage. It delivers 60 V output withstand voltage, 0.2 A AC/DC output current rating, 1 Ω typical on-resistance, and 3750 Vrms input-output isolation for industrial control and telecom switching applications.
For engineers reviewing the ASSR-1219-001E datasheet, pinout, applications, or equivalent options, this page provides verified technical context, exact pin functions, real-world use cases, and validated alternative options for EMR replacement in safety-critical DC and AC signal routing.
Technical Context
The ASSR-1219-001E implements optical coupling between an AlGaAs infrared LED input and a photovoltaic diode array driving two discrete high-voltage MOSFETs. Its turn-on threshold is defined at ≥3 mA input current, and turn-off occurs at ≤0.8 V forward voltage across the LED.
It supports two distinct output configurations: Connection A (AC/DC, 0.2 A, R(ON) ≤10 Ω) and Connection B (DC-only, 0.4 A, R(ON) ≤2.5 Ω), with isolation rated per UL1577 (3750 Vrms, 1 min) and CSA Component Acceptance Notice #5.
Key Specifications

Pinout & Package
ASSR-1219-001E uses a 6-pin DIP through-hole package (300-mil body width). Pin 1 is marked by a dot; pins are numbered left-to-right, top row 1–3, bottom row 4–6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (LED input) | Positive terminal of infrared LED; requires ≥3 mA forward current to activate output. |
| 2 | Cathode (LED input) | Ground return path for LED; voltage ≤0.8 V ensures output remains off. |
| 3 | Common (output) | Shared source node for both internal MOSFETs; connects to load reference point. |
| 4 | Output 1 (drain) | First MOSFET drain terminal; used with Pin 3 for single-pole SPST switching (Connection A or B). |
| 5 | Output 2 (drain) | Second MOSFET drain terminal; enables bidirectional AC/DC operation when paired with Pin 4 and Pin 3. |

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 | 6-pin DIP, 60 V/0.4 A, 1.6 Ω R(ON), 5000 Vrms isolation, higher CTR variation. | Requires higher input current (5 mA typ.) and exhibits wider R(ON) spread across temperature. | Preferred where higher isolation voltage is mandatory and tighter R(ON) tolerance is not required. |
| Vishay VO1263AAC | 6-pin DIP, 60 V/0.25 A, 1.2 Ω R(ON), 5000 Vrms isolation, slower TOFF (0.2 ms). | Lower output current rating and longer turn-off delay limit use in high-speed zone polling systems. | Selected when extended isolation margin outweighs need for sub-100 µs switching in security panel designs. |
Compared with ASSR-1219-001E, TLP3558A offers higher isolation but looser on-resistance consistency, while VO1263AAC trades speed and current capacity for greater voltage margin-making ASSR-1219-001E optimal for balanced performance in telecom and industrial I/O where reliability, speed, and thermal stability are jointly critical.

FAQ
What is the maximum continuous output current for ASSR-1219-001E in AC/DC mode?
The ASSR-1219-001E supports a maximum average output current of 0.2 A in AC/DC configuration (Connection A) at TA = 25°C and TC ≤ 100°C. Derating applies above 25°C ambient, with safe operating area defined in Figure 2 of the AV02-0173EN datasheet. This rating ensures junction temperature remains below 125°C under sustained load.
Does ASSR-1219-001E support DC-only operation, and what are its benefits?
Yes, ASSR-1219-001E supports DC-only operation (Connection B), increasing output current to 0.4 A and reducing typical on-resistance to 0.25 Ω. This configuration eliminates reverse recovery concerns and improves efficiency in unidirectional DC loads such as solenoid drivers and LED arrays, as confirmed in the "Schematics" section of the AV02-0173EN datasheet.
What is the pin 6 function on ASSR-1219-001E, and can it be connected?
Pin 6 on ASSR-1219-001E is designated NC (No Connect) and is internally unconnected. It must remain floating in all PCB layouts-soldering or routing to any net may compromise isolation integrity or cause functional failure. This is explicitly stated in the "Package Outline Drawings" and "Pin Configuration" sections of the AV02-0173EN datasheet.
Is ASSR-1219-001E qualified for automotive applications?
No, ASSR-1219-001E is not AEC-Q100 qualified and is explicitly excluded for automotive or aerospace use per the datasheet caution note. It is rated for industrial and medical applications only, with operating temperature range –40°C to +85°C and safety certifications limited to UL1577 and CSA Component Acceptance-not automotive-grade reliability or qualification testing.
How does the input-output isolation of ASSR-1219-001E compare to industry safety standards?
ASSR-1219-001E provides 3750 Vrms input-output isolation for 1 minute per UL1577 and meets CSA Component Acceptance Notice #5. This satisfies reinforced insulation requirements for many Class I and Class II equipment designs, including IEC 61010-1 and IEC 60601-1, though final system-level compliance depends on PCB layout, creepage/clearance, and end-equipment construction.
