Product details
Overview
ASSR-5211-001E from Broadcom is a high-current, single-pole normally open (1 Form A) solid-state relay featuring optically isolated AlGaAs LED input and dual high-voltage MOSFET output stage. It delivers 600 V output withstand voltage, 0.2 A AC/DC load current rating (Connection A), and 2.5 Ω typical on-resistance in DC-only mode (Connection B), enabling industrial control and factory automation switching where reliability and transient immunity are critical.
For engineers reviewing the ASSR-5211-001E datasheet, pinout, applications, or equivalent options, key selection considerations include input drive compatibility (3 mA min. LED current), dual connection topology (AC/DC vs. DC-only), isolation rating (3750 VRMS), and fast switching (0.7 ms turn-on, 70 µs turn-off at 5 mA).
Technical Context
The ASSR-5211-001E implements an optocoupled architecture with an AlGaAs infrared LED input stage driving a photovoltaic diode array that powers gate driver circuitry for two discrete high-voltage MOSFETs. Its dual-output configuration supports both AC/DC (Connection A) and DC-only (Connection B) topologies, with distinct on-resistance (10 Ω vs. 2.5 Ω) and current ratings (0.2 A vs. 0.4 A).
It operates across –40°C to +85°C, achieves >1 kV/µs output transient immunity and 20 kV/µs input-output transient rejection, and meets UL1577 (3750 VRMS) and CSA Component Acceptance requirements - with optional 5000 VRMS rating available under option X21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Withstand Voltage | 600 V - Supports safe switching of line-voltage AC or high-voltage DC loads without breakdown. |
| Max Output Current (Connection A) | 0.2 A - Rated for general-purpose AC/DC switching in industrial controls and data acquisition systems. |
| Max Output Current (Connection B) | 0.4 A - Enables higher DC load current handling with lower conduction loss in dedicated DC applications. |
| On-Resistance (Connection A) | 10 Ω typical - Defines power dissipation (I²R) and voltage drop during conduction in AC/DC mode. |
| On-Resistance (Connection B) | 2.5 Ω typical - Reduces conduction loss by ~75% vs. Connection A, improving thermal margin for sustained DC loads. |
| Turn-On / Turn-Off Time | 0.7 ms / 0.07 ms typical @ 5 mA - Enables precise timing control in high-speed sequencing and pulse-width modulated loads. |
| Input-Output Isolation | 3750 VRMS (1 min) - Meets basic reinforced insulation requirements per UL1577 for functional safety in industrial equipment. |
Pinout & Package
ASSR-5211-001E 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 device has two isolated terminal groups: pins 1–3 form the input (LED anode/cathode/common), while pins 4–6 constitute the output (MOSFET drain/source/common), enabling bidirectional signal switching with galvanic isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | LED Anode | Positive input terminal for optocoupler LED; requires ≥3 mA forward current to activate relay. |
| Pin 2 | LED Cathode | Negative input terminal; grounding pin 2 with ≥3 mA through pin 1 closes output contacts. |
| Pin 3 | Input Common / NC | No internal connection; electrically isolated from output side; used for mechanical stability only. |
| Pin 4 | Output Source (B) | Common source node for MOSFET pair; tied to load return in Connection B (DC-only) configuration. |
| Pin 5 | Output Drain (A/B) | Main high-side output terminal; connects to load in both Connection A (AC/DC) and Connection B (DC-only). |
| Pin 6 | Output Drain (A) | Secondary high-side terminal used only in Connection A for AC/DC operation; enables bidirectional blocking. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-compatible input drive | 3 mA minimum LED current enables direct interface with microcontroller GPIO or logic buffers without external drivers. |
| Dual-connection topology | Connection A supports universal AC/DC loads; Connection B optimizes for low-loss DC switching via reduced RON. |
| High transient immunity | 7 kV/µs output dV/dt rating prevents false triggering in noisy industrial environments with fast-rising transients. |
| Reinforced optical isolation | 3750 VRMS withstand voltage ensures functional isolation integrity across full operating temperature range (–40°C to +85°C). |
| Precision timing performance | Sub-millisecond switching (0.7 ms TON, 70 µs TOFF) allows use in time-critical PLC I/O and test instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3554(TP,E | 600 V/0.2 A, 16 Ω RON, 1.5 ms TON, 0.2 ms TOFF, SO-6 package | Slower switching, higher RON, smaller footprint; lacks Connection B DC-optimized mode | Preferred when board space is constrained and DC-only optimization is not required. |
| VOL3120T | 600 V/0.12 A, 35 Ω RON, 2 ms TON, 0.5 ms TOFF, DIP-6 package | Lower current rating, higher on-resistance, slower speed; UL recognized but no CSA approval | Suitable for cost-sensitive, lower-power industrial sensors where thermal margin is ample. |
Compared with TLP3554(TP,E and VOL3120T, the ASSR-5211-001E offers superior DC-load efficiency (2.5 Ω RON), faster switching (70 µs TOFF), and dual-connection flexibility - making it optimal for high-duty-cycle, mixed-signal industrial systems requiring both AC and DC switching paths.

FAQ
What is the maximum load voltage the ASSR-5211-001E can safely switch?
The ASSR-5211-001E supports up to 600 V peak output voltage in both AC and DC configurations. In Connection A (AC/DC), it blocks ±600 V; in Connection B (DC-only), it handles 0–600 V DC. Derating applies above 25°C ambient - see Figure 1 and Figure 2 in the datasheet for temperature-dependent current limits. This rating is validated per UL1577 at 3750 VRMS for 1 minute.
Does the ASSR-5211-001E require an external current-limiting resistor on the input LED?
Yes - the ASSR-5211-001E requires an external series resistor to limit forward current to between 3 mA (minimum turn-on) and 20 mA (maximum recommended). At 5 V supply, a 1.5 kΩ resistor sets IF ≈ 3.3 mA; at 3.3 V, a 1.0 kΩ resistor achieves similar. Exceeding 25 mA average input current risks permanent LED degradation, as specified in the Absolute Maximum Ratings table.
How does Connection A differ from Connection B in the ASSR-5211-001E?
Connection A uses pins 5 and 6 as complementary output terminals, enabling bidirectional AC/DC switching with 10 Ω typical RON and 0.2 A rating. Connection B ties pins 4 and 5 together as source and drain respectively, optimizing for unidirectional DC loads with 2.5 Ω RON and 0.4 A rating. Pin 3 remains unconnected in both configurations.
Is the ASSR-5211-001E RoHS compliant and lead-free?
Yes - the "-001E" suffix explicitly denotes a RoHS 6-compliant, lead-free version of the ASSR-5211-001E. It meets JEDEC J-STD-020 reflow profiles and carries the "Lead (Pb) Free" and "RoHS 6 fully compliant" markings on the package per Broadcom's AV02-0152EN datasheet revision.
What safety certifications does the ASSR-5211-001E hold?
The ASSR-5211-001E is UL recognized per UL1577 (3750 VRMS, 1 minute) and CSA approved under Component Acceptance Notice #5. An optional x21 variant provides 5000 VRMS rating - however, the standard ASSR-5211-001E carries the base 3750 VRMS certification, sufficient for most industrial and medical BF-rated applications requiring reinforced insulation.
