Product details
Overview
ADUM3201TRZ-EP from Analog Devices is a dual-channel, reinforced digital isolator using iCoupler® transformer-based technology for galvanic signal isolation across high-voltage barriers. It supports 25 Mbps data rate, operates from −55°C to +125°C, delivers 560 VPEAK working voltage per VDE V 0884-10, and features asymmetric channel configuration (1 input/1 output per side) in an 8-lead narrow-body SOIC package. It is used in SPI isolation and battery monitor interfaces in hybrid electric vehicles.
For engineers reviewing the ADUM3201TRZ-EP datasheet, ADUM3201TRZ-EP pinout, ADUM3201TRZ-EP application, or ADUM3201TRZ-EP equivalent, key selection criteria include its military-grade temperature range, 25 kV/µs common-mode transient immunity, dual-supply flexibility (3.3 V/5 V), and VDE-certified reinforced insulation for safety-critical systems.
Technical Context
The ADUM3201TRZ-EP implements two independent unidirectional isolation channels with fixed input/output assignment per side: VIA and VIB are inputs on Side 1; VOA and VOB are outputs on Side 2. Its monolithic transformer architecture eliminates LED aging and timing drift inherent in optocouplers, enabling stable propagation delay (≤45 ns at 5 V) and low pulse width distortion (≤4 ns).
It supports mixed-voltage operation-VDD1 and VDD2 may be independently set to 3.3 V or 5 V-enabling level translation across the isolation barrier. Refresh circuitry maintains DC correctness during power loss, with output state recovery within 1 µs after supply restoration on either side.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 25 Mbps - Enables high-speed SPI and digital field bus isolation without protocol throttling. |
| Propagation Delay | ≤45 ns at 5 V - Ensures tight timing alignment in real-time control loops and synchronous interfaces. |
| Common-Mode Transient Immunity | >25 kV/µs - Maintains signal integrity in noisy motor drive or battery pack environments. |
| Working Voltage (VIORM) | 560 VPEAK - Certified for reinforced insulation per VDE V 0884-10, supporting 400 Vrms mains-connected systems. |
| Operating Temperature | −55°C to +125°C - Qualified for defense, aerospace, and under-hood automotive applications per AQEC standard. |
| Supply Flexibility | 3.0–5.5 V on both sides - Allows direct interfacing with 3.3 V microcontrollers and 5 V peripherals without external level shifters. |
| Power Consumption | 1.1 mA/channel at 1 Mbps (3.3 V) - Reduces thermal load in compact, sealed modules. |
Pinout & Package
ADUM3201TRZ-EP uses an 8-lead narrow-body SOIC (R-8) package per JEDEC MS-012-AA, with creepage and clearance ≥4.0 mm between input and output sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | Input-side supply | Provides power to Side 1 encoder; must be decoupled locally for noise immunity. |
| 2 - VOA | Output A | Isolated output driven by input VIA; matches VIA logic state with ≤45 ns delay. |
| 3 - VIB | Input B | Second logic input on Side 1; enables bidirectional data flow when paired with VOA/VOB. |
| 4 - GND1 | Input-side ground | Reference return for VDD1 and Side 1 signals; must be isolated from GND2. |
| 5 - GND2 | Output-side ground | Reference return for VDD2 and Side 2 outputs; forms isolation barrier boundary. |
| 6 - VOB | Output B | Isolated output driven by input VIB; complements VOA for full-duplex SPI clock/data separation. |
| 7 - VIA | Input A | Primary logic input on Side 1; drives VOA with precise edge timing. |
| 8 - VDD2 | Output-side supply | Provides power to Side 2 decoder; enables independent voltage domain operation. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced insulation certification | VDE V 0884-10 approval with VIORM = 560 VPEAK ensures compliance in medical and industrial safety-critical designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3200TRZ-EP | Two inputs on Side 1, zero outputs on Side 1; symmetric input-only configuration. | Optimized for unidirectional data paths (e.g., sensor-to-processor), not full-duplex SPI. | Select ADUM3200TRZ-EP only when both signals originate on the same side and require no local feedback. |
| SI8621ED-IS | Capacitive isolation; 25 Mbps; 5 kVrms rating; operates from −40°C to +125°C (not −55°C). | Lacks AQEC qualification and VDE-reinforced certification; limited to commercial/industrial use. | Choose SI8621ED-IS for cost-sensitive, non-military applications where extended temperature and safety certification are not required. |
Compared with ADUM3200TRZ-EP and SI8621ED-IS, ADUM3201TRZ-EP uniquely combines asymmetric I/O mapping, −55°C capability, and VDE-reinforced insulation-making it the only option qualified for full-duplex SPI isolation in defense-grade battery monitoring systems.

FAQ
What is the maximum data rate supported by ADUM3201TRZ-EP?
ADUM3201TRZ-EP supports a maximum data rate of 25 Mbps across its dual isolation channels. This specification is guaranteed over the full −55°C to +125°C operating temperature range and applies to both 3.3 V and 5 V supply configurations, as verified in Tables 1, 4, 7, and 10 of the ADuM3200-EP/ADuM3201-EP Rev. B datasheet.
Does ADUM3201TRZ-EP support mixed-voltage operation?
Yes, ADUM3201TRZ-EP supports independent 3.3 V or 5 V supplies on VDD1 and VDD2. Electrical characteristics for mixed configurations (5 V/3.3 V and 3.3 V/5 V) are fully specified in Tables 7–12 of the datasheet, including propagation delay ≤50 ns and supply current matching typical operation modes.
What safety certifications apply to ADUM3201TRZ-EP?
ADUM3201TRZ-EP carries pending VDE certification per DIN V VDE V 0884-10 (reinforced insulation, VIORM = 560 VPEAK), UL 1577 recognition (2500 Vrms, 1 minute), and CSA Component Acceptance Notice 5A. The device is marked with an asterisk (*) to indicate VDE compliance upon final approval.
How does ADUM3201TRZ-EP handle power loss on one side?
ADUM3201TRZ-EP incorporates refresh circuitry that maintains output logic states during brief interruptions. If VDD1 fails, VOA and VOB retain their last valid states until VDD1 is restored; if VDD2 fails, outputs go indeterminate but recover within 1 µs of VDD2 restoration, as defined in Table 21 of the datasheet.
What is the pin configuration difference between ADUM3201TRZ-EP and ADUM3200TRZ-EP?
ADUM3201TRZ-EP has asymmetric I/O mapping: Pin 2 = VOA (output), Pin 7 = VIA (input); ADUM3200TRZ-EP is symmetric: Pins 2 and 3 = VIA/VIB (both inputs), Pins 6 and 7 = VOA/VOB (both outputs). This makes ADUM3201TRZ-EP suitable for full-duplex protocols like SPI, while ADUM3200TRZ-EP suits unidirectional sensor links.
