Product details
Overview
ASSR-601J-000E from Broadcom is a 1-Form-A solid-state relay (SSR) featuring optically isolated AlGaAs LED input and dual high-voltage MOSFET output stage, rated for 1500 VOFF, <250 Ω RON at 50 mA, and 4 ms max turn-on time. It replaces electromechanical relays in high-isolation industrial sensing and battery management systems.
For engineers reviewing the ASSR-601J-000E datasheet, pinout, applications, or equivalent options, key selection criteria include reinforced insulation (8.3 mm creepage/clearance), 1414 VPEAK working voltage, avalanche-rated MOSFETs, and SO-16 package compatibility with high-temp (–40°C to +110°C) operation.
Technical Context
The ASSR-601J-000E implements galvanic isolation via an AlGaAs LED optically coupled to a photovoltaic diode array and integrated driver that controls two discrete high-voltage MOSFETs. Its bidirectional output switch operates without auxiliary power on the load side.
It delivers reinforced insulation per IEC/EN/DIN EN 60747-5-5 and UL 1577 (5000 VRMS/1 min), with internal clearance ≥0.5 mm and input-output resistance >109 Ω at 1000 VDC. The device supports safe switching of up to 1000 VDC loads with leakage current ≤10 nA at 1000 V.
Key Specifications

|---|---|
| Output Withstand Voltage | 1500 V at IDSS = 250 μA - enables safe isolation in 1000 VDC industrial bus monitoring |
| On-Resistance (RON) | <250 Ω at IO = 50 mA - ensures low conduction loss in BMS flying-capacitor sensing paths |
| Turn-On/Off Time | TON < 4 ms / TOFF < 0.5 ms - supports fast cycling in inrush current limiting and leakage detection |
| Input Threshold Current | 10 mA min - compatible with standard microcontroller GPIO drive capability via series resistor |
| Isolation Rating | 5000 VRMS/1 min (UL1577), VIORM = 1414 VPEAK - meets reinforced insulation requirements for automotive and industrial safety standards |
| Operating Temperature | –40°C to +110°C - supports deployment in under-hood automotive and high-temp factory automation environments |
| Creepage/Clearance | ≥8.3 mm (input-to-output) - satisfies IPC-2221B Class B spacing for 1000 V working voltage |
Pinout & Package
ASSR-601J-000E is housed in a 300-mil SOIC-16 (SO-16) surface-mount package with 1.27 mm pitch, RoHS-compliant lead finish, and JEDEC J-STD-020 reflow profile compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6, 7, 8 | NC | No internal connection; must remain unconnected per design |
| 3 | NC | Internally tied to Pin 5 (CA); do not connect externally |
| 4 | AN | Anode of input AlGaAs LED - requires current-limiting resistor to microcontroller or logic driver |
| 5 | CA | Cathode of input LED - referenced to control-side ground (GND1) |

Applications
| Battery Insulation Monitoring | BMS Flying Capacitor Sensing |
|---|---|
|
Use Scenario: Measuring insulation resistance between EV battery pack terminals and chassis ground to detect degradation or moisture ingress. IC Role / Device Role / Timing Role: High-voltage SSR acting as a programmable isolation switch to apply test voltage and isolate measurement circuitry. Use Value: 1500 VOFF rating and ≤10 nA leakage ensure accurate sub-MΩ resistance readings without loading the DUT. |
Use Scenario: Switching flying capacitors in multi-cell battery voltage monitoring ICs to sequentially sample cell voltages without dedicated level-shifters. IC Role / Device Role / Timing Role: Bidirectional, zero-power-output solid-state switch enabling charge redistribution across series-connected cells. Use Value: No auxiliary supply needed on high-side; 0.5 ms turn-off prevents cross-conduction during capacitor reconfiguration. |
| EMR Replacement in Industrial Controls | Inrush Current Limiting |
|
Use Scenario: Replacing 1-Form-A electromechanical relays in PLC I/O modules where contact wear, bounce, and EMI are unacceptable. IC Role / Device Role / Timing Role: Solid-state replacement providing silent, bounce-free switching with 4 ms max turn-on for deterministic timing. Use Value: 100% duty-cycle capability and 110°C operation extend service life beyond mechanical relay limits in fan-cooled cabinets. |
Use Scenario: Controlling NTC thermistor bypass in AC/DC power supplies to limit cold-start inrush into bulk capacitors. IC Role / Device Role / Timing Role: High-voltage switch triggered after delay to short out inrush limiter once bulk cap is charged. Use Value: Avalanche rating absorbs energy from inductive kickback; 250 Ω RON minimizes steady-state conduction loss. |
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 TLP3548A | SO-16, 1500 VOFF, but RON = 350 Ω typical at 50 mA; no avalanche rating | Limited to lower-current (<30 mA) switching; unsuitable for high-energy transient environments | Consider only if cost sensitivity outweighs reliability requirements in non-safety-critical circuits |
| Vishay VO3120 | SO-8, 600 VOFF, 1.2 A load current, but only 5 mm creepage; lacks IEC 60747-5-5 certification | Not suitable for 1000 VDC systems or reinforced insulation requirements; limited to lower-voltage industrial controls | Select only for space-constrained designs operating below 600 VDC with basic isolation needs |
Compared with TLP3548A and VO3120, the ASSR-601J-000E uniquely combines 1500 VOFF, 8.3 mm creepage, IEC 60747-5-5 certification, and avalanche-rated MOSFETs-making it the only option qualified for functional safety–aligned battery insulation testing and high-reliability industrial HV switching.

FAQ
What is the minimum input current required to turn on the ASSR-601J-000E?
The ASSR-601J-000E turns on with a minimum input current of 10 mA through its AlGaAs LED. This threshold is guaranteed over the full operating temperature range (–40°C to +110°C). At 25°C, typical turn-on occurs at 7 mA, but design should target ≥10 mA to ensure reliable activation across all conditions. The ASSR-601J-000E does not require additional biasing or gate drive circuitry on the output side.
Does the ASSR-601J-000E support bidirectional load current flow?
Yes, the ASSR-601J-000E functions as a bidirectional switch due to its dual-MOSFET output architecture with symmetric drain terminals (Pins 9/10 and 15/16). It conducts equally in both directions when ON and blocks voltage up to 1500 V in either polarity when OFF. This makes the ASSR-601J-000E ideal for AC-coupled sensing and floating-node applications like BMS flying capacitor topologies.
What safety certifications does the ASSR-601J-000E hold?
The ASSR-601J-000E is certified to IEC/EN/DIN EN 60747-5-5 for reinforced insulation, UL 1577 (5000 VRMS/1 minute), and CSA Component Acceptance. Its maximum working insulation voltage is 1414 VPEAK, with validated creepage and clearance ≥8.3 mm between input and output. These certifications are explicitly documented for the ASSR-601J-000E in Broadcom's official datasheet revision DS101.
Can the ASSR-601J-000E replace electromechanical relays directly on existing PCBs?
The ASSR-601J-000E uses a standard 300-mil SO-16 footprint identical to many industry-standard relay drivers and optocouplers, enabling drop-in replacement in many cases. However, layout must respect its 8.3 mm input-output creepage requirement-floating pins (8–9 and 15–16) must not be bridged by copper, and control/output traces must maintain ≥8 mm separation. The ASSR-601J-000E eliminates mechanical wear but requires attention to thermal dissipation under continuous 50 mA load.
What is the maximum continuous load voltage the ASSR-601J-000E can switch?
The ASSR-601J-000E is rated for continuous load voltage up to 1000 VDC across its output terminals (Pins 9/10 and 15/16). Its 1500 VOFF withstand rating applies to transient blocking capability at IDSS = 250 μA. For reliable long-term operation, the applied DC voltage should not exceed 1000 V, and transient overvoltages must stay within the VIOTM limit of 6000 VPEAK. This specification is confirmed in the "Recommended Operating Conditions" table of the ASSR-601J-000E datasheet.
