Product details
Overview
ASSR-601J-500E from Broadcom is a high-voltage solid-state relay (SSR) with optically isolated 1-Form-A switching function, featuring 1500 V output withstand voltage, <250 Ω on-resistance at 50 mA load, and <4 ms turn-on time. It replaces electromechanical relays in high-isolation industrial sensing and battery management systems.
For engineers reviewing the ASSR-601J-500E datasheet, pinout, applications, or equivalent options, key selection criteria include reinforced insulation (IEC/EN/DIN EN 60747-5-5), 8 mm input-output creepage, bidirectional MOSFET output, and SO-16 surface-mount packaging for high-voltage signal isolation.
Technical Context
The ASSR-601J-500E implements optical coupling between an AlGaAs LED input stage and a photovoltaic diode array driver that controls two avalanche-rated high-voltage MOSFETs. Its dual-drain architecture (D1 and D2) enables bidirectional conduction without external bias.
It operates as a galvanically isolated, zero-power-output switch with no gate drive requirement on the output side. Input control requires only 7–30 mA forward current, and turn-off occurs at ≤0.4 V cathode-anode voltage - enabling direct microprocessor GPIO interfacing with minimal external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6, 7, 8 | NC | No internal connection; must remain unconnected or floating on PCB. |
| 3 | NC | Internally tied to Pin 5 (CA); do not connect externally. |
| 4 | AN | Anode of input AlGaAs LED - connects to current-limited positive supply. |
| 5 | CA | Cathode of input LED - connects to ground or active-low control signal. |
| 9, 10 | D2 | Drain terminal of second MOSFET - forms one side of bidirectional output path. |

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 V VOFF, but single-MOSFET output (unidirectional); RON ≈ 350 Ω at 50 mA. | Limited to DC-only switching; unsuitable for flying-capacitor AC sampling or bidirectional BMS topologies. | Select when cost sensitivity outweighs bidirectionality and lower on-resistance requirements. |
| Vishay VO3120 | SO-8, 600 V VOFF, higher leakage (100 nA), no IEC 60747-5-5 certification; TOFF ≈ 1 ms. | Not rated for 1000 VDC systems; insufficient creepage (<4 mm) for reinforced insulation compliance. | Acceptable only in non-safety-critical, low-voltage (<400 V) industrial controls where certification is not mandated. |
Compared with TLP3548A and VO3120, the ASSR-601J-500E uniquely delivers bidirectional conduction, 8 mm creepage, and IEC 60747-5-5 certification - making it the only option qualified for reinforced-insulation battery insulation resistance measurement and high-voltage BMS sensing.

FAQ
What is the maximum continuous load voltage supported by the ASSR-601J-500E?
The ASSR-601J-500E supports a continuous load voltage of up to 1000 VDC across its output terminals (pins 9/10 and 15/16). This rating is specified in the Recommended Operating Conditions table and aligns with its 1500 V output withstand voltage at IDSS = 250 μA - ensuring safe operation in high-voltage battery and solar applications where the ASSR-601J-500E is commonly deployed.
Does the ASSR-601J-500E require an external gate drive circuit on the output side?
No, the ASSR-601J-500E does not require external gate drive. Its internal photovoltaic diode array generates sufficient gate voltage to fully enhance both high-voltage MOSFETs when the input LED is driven with ≥10 mA. This self-contained drive architecture eliminates external bias components and simplifies design - a core feature of the ASSR-601J-500E's solid-state relay functionality.
Can pins 9 and 10 (D2) be used independently from pins 15 and 16 (D1) in the ASSR-601J-500E?
No - pins 9 and 10 are internally connected as a single drain node (D2), and pins 15 and 16 are internally connected as another single drain node (D1). They form the two terminals of a bidirectional switch. Using them independently would violate the device's internal topology and is not supported. The ASSR-601J-500E functions only as a two-terminal output device between D1 and D2.
What safety certifications apply specifically to the ASSR-601J-500E variant?
The ASSR-601J-500E carries IEC/EN/DIN EN 60747-5-5 certification, UL 1577 recognition (5000 VRMS, 1 minute), and CSA component acceptance. These approvals are explicitly confirmed in the ordering information for the "-500E" suffix, which denotes tape-and-reel packaging with full regulatory compliance - distinguishing it from non-certified variants like -000E.
How does the ASSR-601J-500E achieve bidirectional switching capability?
The ASSR-601J-500E achieves bidirectional switching through its dual-MOSFET architecture: two avalanche-rated high-voltage MOSFETs are connected back-to-back (source-to-source) between D1 and D2. This configuration allows current flow in either direction when the device is ON, eliminating polarity dependence - a defining functional trait of the ASSR-601J-500E that enables use in AC-coupled and floating-node applications like BMS flying capacitors.
