Product details
Overview
MURB1620CT-T-F from Diodes Incorporated is a 16A, 200V surface-mount super-fast rectifier in D2PAK (TO-263) package with dual common-cathode configuration, 25ns reverse recovery time, 0.975V forward voltage at 8A, and 1.5°C/W junction-to-case thermal resistance - used in high-frequency AC/DC front-end rectification for industrial SMPS and PFC stages.
For engineers reviewing the MURB1620CT-T-F datasheet, MURB1620CT-T-F pinout, MURB1620CT-T-F application, or MURB1620CT-T-F equivalent, key selection criteria include peak repetitive reverse voltage (200V), average rectified current at TC=125°C (16A), surge rating (100A), low trr (25ns), and thermal performance under forced-air or PCB copper heatsinking.
Technical Context
This dual common-cathode ultrafast rectifier employs diffused-junction, glass-passivated die construction to achieve consistent switching behavior and low leakage across temperature. Its 25ns recovery time enables operation in 100–500kHz PFC and boost converters without excessive switching loss.
The device supports single-phase half-wave rectification with 200V DC blocking capability and is rated for 16A average output current when case temperature is maintained at ≤125°C using ≥5 mm² copper pad heatsinking per element.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in bridge or PFC applications. |
| IO @ TC=125°C | 16 A - Sustained average forward current per diode element when mounted on 5 mm² copper pad; sets continuous power handling limit. |
| trr | 25 ns - Measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables efficient high-frequency switching with minimal reverse recovery loss. |
| VFM @ IF=8A | 0.975 V - Forward voltage drop per diode at 8A; directly impacts conduction loss and thermal design in high-current paths. |
| RJC | 1.5 °C/W - Junction-to-case thermal resistance; determines required heatsink interface performance for safe operation at full load. |
| IFSM | 100 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush current tolerance during system startup or line transients. |
Pinout & Package
Package: D2PAK (TO-263), surface-mount, molded plastic body with solderable terminals per MIL-STD-202 Method 208; polarity marked on top surface; weight ≈1.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input terminal for first rectifying path; connects to AC line or transformer secondary. |
| Pin 2 & Pin 4 | Common Cathode | Shared cathode node for both diodes; serves as DC output reference point in dual-output or center-tap configurations. |
| Pin 3 | Anode of Diode 2 | Input terminal for second rectifying path; enables dual-anode, single-cathode topology for compact full-wave solutions. |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast recovery time | 25 ns - Reduces switching losses in high-frequency converters operating above 100 kHz. |
| Glass passivated die | Enhanced moisture and contamination resistance - improves long-term reliability in humid or industrial environments. |
| Diffused junction | Controlled carrier lifetime - ensures stable trr and low IR across temperature and aging. |
| UL 94V-0 plastic housing | Flame-retardant encapsulation - meets safety requirements for enclosed power supplies and industrial equipment. |
Applications
| Industrial SMPS Input Stage | PFC Boost Rectifier |
|---|---|
Use Scenario: AC/DC conversion in 1–3 kW industrial switch-mode power supplies with universal input (85–265 VAC). IC Role / Device Role / Timing Role: Dual-anode superfast rectifier providing full-wave input rectification before the PFC stage. Use Value: 25 ns trr minimizes dead-time losses and EMI generation during high-frequency line-frequency switching. | Use Scenario: Output rectification in active PFC boost circuits operating at 65–150 kHz. IC Role / Device Role / Timing Role: High-current, low-loss output diode handling discontinuous conduction mode (DCM) or critical conduction mode (CrCM) currents. Use Value: 0.975 V VFM at 8A reduces conduction loss by ~15% vs. standard fast recovery diodes, improving efficiency at full load. |
| Motor Drive DC Bus | Uninterruptible Power Supply (UPS) |
Use Scenario: DC bus rectification in 3-phase inverter front-ends for HVAC and pump drives. IC Role / Device Role / Timing Role: Secondary-side rectifier converting regenerated energy or auxiliary supply AC to regulated DC bus. Use Value: 100A IFSM withstands motor stall surges and regenerative braking transients without degradation. | Use Scenario: Line-frequency rectification in double-conversion UPS systems with battery backup. IC Role / Device Role / Timing Role: Primary rectifier delivering clean DC to inverter stage while supporting hold-up time via bulk capacitors. Use Value: Low IR (5 µA @ 25°C) prevents capacitor self-discharge during standby, extending battery runtime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | 200V VRRM, 16A IO, 35ns trr, TO-247 package | Higher trr increases switching loss in >100kHz designs; through-hole mounting requires different PCB layout. | Select when higher surge margin (120A IFSM) and legacy through-hole assembly are prioritized over footprint size. |
| IXYS MUR1620CT | 200V VRRM, 16A IO, 30ns trr, D2PAK package, same pinout | Slightly slower recovery adds ~5% conduction + switching loss in 150kHz PFC; identical thermal interface. | Choose for drop-in replacement where minor efficiency trade-off is acceptable and second-source qualification is required. |
Compared with STTH1602CW and IXYS MUR1620CT, the MURB1620CT-T-F delivers the fastest recovery (25ns), lowest forward voltage (0.975V), and optimized surface-mount thermal interface - making it preferred for space-constrained, high-efficiency 100–200kHz industrial power supplies.

FAQ
What is the maximum allowable case temperature for continuous 16A operation?
The MURB1620CT-T-F is rated for 16A average forward current only when the case temperature (TC) is held at or below 125°C. This requires mounting on a minimum 5.0 mm² copper pad (0.013 mm thick) acting as a heatsink. Exceeding 125°C derates current linearly per Fig. 1 in the datasheet, reaching zero at 150°C.
Does this device support full-wave bridge configuration without external diodes?
No. The MURB1620CT-T-F has a dual common-cathode configuration (Anode1–Cathode–Anode2), not a full-bridge topology. It can be used as two independent rectifiers or in center-tapped transformer configurations, but building a full-wave bridge requires four discrete diodes or a dedicated bridge rectifier IC.
How does the 25ns recovery time impact EMI in high-frequency designs?
A 25ns trr significantly reduces reverse recovery di/dt and associated high-frequency ringing, lowering conducted and radiated EMI in 100–500kHz PFC and LLC resonant converters. This allows smaller EMI filters and relaxed layout constraints compared to 50–100ns diodes, especially when paired with SiC or GaN switches.
Is the D2PAK package compatible with standard reflow profiles for lead-free soldering?
Yes. The MURB1620CT-T-F's D2PAK package is qualified for lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260°C for ≤30 seconds, with ramp rates ≤3°C/s. Thermal mass requires careful profiling - preheat to 150°C, soak at 180–200°C for 60–120s, then ramp to peak.
