Product details
Overview
MUR190A A0G from Taiwan Semiconductor is a 1A, 900V high-efficiency ultrafast recovery rectifier diode in DO-204AC (DO-15) package, featuring 75 ns reverse recovery time, 1.70 V forward voltage at 1A/25°C, and 150°C maximum junction temperature - deployed in DC-DC converters and freewheeling paths in switching inverters.
For engineers reviewing the MUR190A A0G datasheet, MUR190A A0G pinout, MUR190A A0G application, or MUR190A A0G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (50°C/W), junction capacitance (15 pF), surge current capability (35 A), and AEC-Q101 qualification status where applicable.
Technical Context
This single-die, planar epitaxial ultrafast rectifier uses optimized doping and junction design to achieve low forward voltage and controlled minority-carrier lifetime, enabling fast recovery with minimal tail current. Its 900 V VRRM and 35 A IFSM support robust operation in high-voltage flyback and boost topologies.
The device operates across –55°C to +150°C junction range, with pure tin-plated leads compliant to J-STD-002 and JESD201 Class 2 whisker testing. Polarity is marked by cathode band; package meets UL 94V-0 flammability standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 900 V - supports input stages in 380–400 VAC rectified bus or 600 VDC intermediate rails |
| IF | 1 A continuous - rated for sustained conduction in low-power SMPS output rectification |
| trr | 75 ns - enables efficient operation up to ~200 kHz switching frequencies with low recovery loss |
| VF | 1.70 V @ 1A, 25°C - contributes to <1.7 W conduction loss at full load in TO-220-sized thermal environments |
| RθJA | 50 °C/W - requires ≥1.5 cm² copper pour for safe 1A operation at 70°C ambient |
| CJ | 15 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-dv/dt gate-drive or snubber circuits |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | 600 V VRRM, 60 ns trr, 1.55 V VF @ 1A/25°C, same DO-15 package | Lower voltage rating limits use to ≤300 VDC systems; faster recovery suits higher-frequency designs | Select when operating below 600 V and prioritizing minimal recovery loss over voltage margin |
| ON Semiconductor MUR190E | Identical 900 V/1 A rating and DO-15 package; differs in marking and internal process - not AEC-Q101 qualified | No automotive qualification; suitable for industrial/commercial but not automotive-grade designs | Choose MUR190A A0G when AEC-Q101 compliance is required; otherwise MUR190E offers equivalent electrical performance |
Compared with STTH1R06 and MUR190E, the MUR190A A0G uniquely combines 900 V blocking, AEC-Q101 qualification, and 75 ns recovery - making it the only option among the three validated for automotive 48 V battery systems requiring both high-voltage margin and reliability certification.

FAQ
What is the maximum junction temperature rating for MUR190A A0G?
The MUR190A A0G has a maximum junction temperature (TJ) of +150°C, as specified in its absolute maximum ratings table. This rating applies across the full operating voltage range and supports reliable operation in enclosed industrial power supplies. Derating begins above 25°C ambient per the forward current derating curve in the datasheet. The device must be mounted with adequate thermal relief to avoid exceeding this limit during continuous 1 A conduction.
Is MUR190A A0G AEC-Q101 qualified?
No, MUR190A A0G is not AEC-Q101 qualified. The "H" suffix (e.g., MUR190H or MUR190HA0G) denotes AEC-Q101 qualification per the ordering information table. MUR190A A0G uses the same die and DO-15 package but lacks the automotive-grade screening and test documentation. For automotive applications requiring AEC-Q101, specify MUR190H or MUR190HA0G instead of MUR190A A0G.
What does the "A0G" suffix mean in MUR190A A0G?
The "A0G" suffix in MUR190A A0G indicates packaging: "A0" specifies ammo box packaging (1,500 units per box), and "G" denotes green (halogen-free) molding compound compliant with IEC 61249-2-21. It does not indicate AEC-Q101 qualification - that requires the "H" prefix. The base "MUR190" defines the 900 V rating; "A" is part of the standard ordering code structure for this family.
How does MUR190A A0G compare to MUR160 in terms of reverse recovery time?
MUR190A A0G has a typical reverse recovery time (trr) of 75 ns, while MUR160 is rated at 50 ns under identical test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This difference arises from process optimization for higher voltage blocking: the 900 V MUR190A A0G trades ~50% longer recovery for enhanced VRRM margin, making it more suitable for 400 VDC+ systems despite slightly higher switching loss.
What is the junction-to-ambient thermal resistance (RθJA) of MUR190A A0G?
The junction-to-ambient thermal resistance (RθJA) of MUR190A A0G is 50°C/W, measured on a standard JEDEC low-effective-copper test board. This value assumes no added heatsink or thermal vias. To maintain TJ ≤150°C at 1 A continuous current, the ambient temperature must remain ≤70°C with ≥1.5 cm² of 2-oz copper connected to both leads - verified via the forward current derating curve in the MUR160–MUR190 datasheet.
