Product details
Overview
ASSR-601JT-000E from Broadcom is an automotive-grade solid-state Photo MOSFET relay with reinforced R2Coupler™ isolation, designed as a 1FormA EMR replacement for high-voltage battery monitoring circuits. It features 1500 V output withstand voltage, <250 Ω on-resistance at 10 mA load, 0.5 ms max turn-off time, and operates across –40°C to +125°C ambient temperature in battery insulation resistance measurement and BMS flying capacitor sensing.
For engineers reviewing the ASSR-601JT-000E datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact SO-16 pin mapping, AEC-Q101 qualification status, leakage and timing specs under 1000 VDC bias, and real-world BMS isolation use cases - all confirmed from Broadcom's June 2024 DS105 datasheet.
Technical Context
The ASSR-601JT-000E integrates an AlGaAs infrared LED input stage optically coupled to a photovoltaic diode array and driver circuit that controls two discrete high-voltage MOSFETs. Its bidirectional output switch requires no external power on the load side and achieves galvanic isolation via ≥8 mm creepage/clearance between input (pins 4–5) and output (pins 9–10, 15–16).
It uses avalanche-rated MOSFETs with 1500 V BVDSS and supports continuous 1000 VDC load voltage. Turn-on is triggered by ≥7 mA LED current; turn-off occurs when input voltage drops to ≤0.4 V. The device is rated for 5000 VRMS/1 min isolation per UL1577 and VIORM = 1414 VPEAK per IEC/EN/DIN EN 60747-5-5.

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 | SO-16, 1500 V BVDSS, but rated only to +105°C; IOFF = 1 µA @ 1000 V - tighter leakage but lower thermal margin. | Limited to under-dash automotive or industrial BMS where ambient stays ≤105°C. | Select when leakage budget is stricter than thermal range requirement. |
| Vishay VO3120 | SO-8, 600 V BVDSS, TOFF = 0.5 ms, but lacks AEC-Q101 qualification and has 4 mm creepage - not suitable for reinforced isolation. | Acceptable for low-voltage (<400 V) industrial SMPS feedback, not for EV battery systems. | Choose only for cost-sensitive non-automotive 600 V applications with no safety certification needed. |
Compared with TLP3547 and VO3120, the ASSR-601JT-000E uniquely combines AEC-Q101 qualification, +125°C operation, 1500 V withstand, and 8.3 mm creepage - making it the only drop-in option for ISO 26262-compliant high-voltage battery monitoring where thermal robustness and reinforced isolation are co-required.

FAQ
What is the maximum continuous load voltage supported by the ASSR-601JT-000E?
The ASSR-601JT-000E supports a continuous load voltage of up to 1000 VDC across its output terminals (pins 9–10 and 15–16). This rating is validated under recommended operating conditions and aligns with its 1500 V output withstand voltage (BVDSS) at IDSS = 250 µA, ensuring safe operation in high-voltage EV battery monitoring circuits.
Does the ASSR-601JT-000E require external power on the output side to operate?
No, the ASSR-601JT-000E does not require external power on the output side. Its photovoltaic gate drive architecture generates sufficient gate voltage from the input LED current to fully enhance both internal MOSFETs, enabling true bidirectional switching without auxiliary supply - a key advantage over opto-IC relays in isolated BMS sensing paths.
How is the ASSR-601JT-000E qualified for automotive use?
The ASSR-601JT-000E is fully qualified to AEC-Q101 standards, including stress testing for high-temperature reverse bias (1200 V), human body model ESD (2000–4000 V), and charge device model ESD (750–1000 V). Its –40°C to +125°C operating range and reinforced insulation meet ISO 26262 functional safety prerequisites for ASIL-B/C battery system monitoring.
What is the purpose of the NC pins (1, 2, 3, 6, 7, 8) on the ASSR-601JT-000E?
Pins 1, 2, 6, 7, and 8 are true no-connect terminals with no internal connection. Pin 3 is internally tied to pin 5 (cathode) and must remain unconnected externally to avoid compromising LED biasing. All NC pins are electrically isolated and serve mechanical or packaging roles - they must not be routed or soldered in PCB layout.
Can the ASSR-601JT-000E replace electromechanical relays in battery insulation testing?
Yes, the ASSR-601JT-000E is explicitly designed as a 1FormA EMR replacement for battery insulation resistance measurement. Its sub-µA off-state leakage, 1500 V withstand capability, and 0.5 ms turn-off time directly address the precision, safety, and speed requirements of ISO 6469-3 compliant test systems - with added benefits of silent operation, infinite cycle life, and zero contact bounce.
