Product details
Overview
VS-MURB1520TRRPBF from Vishay Semiconductors is an ultrafast recovery rectifier optimized for high-efficiency SMPS output stages, featuring 200 V peak repetitive reverse voltage (VRRM), 15 A average forward current (IF(AV)), 35 ns reverse recovery time (trr) at 1.0 A/50 A/μs, 0.85 V forward voltage drop at 15 A and 150 °C, and 175 °C maximum junction temperature - deployed as a freewheeling diode in low-voltage inverters and chopper motor drives.
For engineers reviewing the VS-MURB1520TRRPBF datasheet, VS-MURB1520TRRPBF pinout, VS-MURB1520TRRPBF application, or VS-MURB1520TRRPBF equivalent, key selection criteria include ultrafast trr under high dI/dt conditions, low Qrr (19 nC typ. at 25 °C), thermal robustness up to 175 °C, and D2PAK (TO-263AB) package compatibility with high-power PCB layouts.
Technical Context
This device employs platinum-doped lifetime control in a planar silicon structure to achieve precise balance between low forward voltage (VF) and ultrafast recovery (trr ≤ 35 ns). Its stored charge (Qrr) is minimized to reduce switching losses in hard-switched topologies.
The D2PAK (TO-263AB) package provides low thermal resistance (RthJC = 1.5 °C/W) and supports direct heatsink mounting via the exposed cathode tab. It operates reliably across -65 °C to +175 °C junction temperature range with MSL Level 1 moisture sensitivity rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands peak reverse transients in 12–48 V DC/DC and UPS output stages without breakdown. |
| IF(AV) | 15 A at TC = 150 °C - Sustains continuous conduction in high-current SMPS secondary-side rectification. |
| trr | 35 ns (TJ = 25 °C, IF = 1.0 A, dI/dt = 50 A/μs) - Enables operation at >100 kHz switching frequencies with minimal tail current loss. |
| VF | 0.85 V at IF = 15 A, TJ = 150 °C - Reduces conduction loss and thermal stress in thermally constrained designs. |
| Qrr | 19 nC typical at TJ = 25 °C - Low stored charge minimizes snubber dissipation and EMI generation during turn-off. |
| RthJC | 1.5 °C/W - Enables efficient heat transfer to external heatsink, supporting high ambient temperature operation. |
| TJ(max) | 175 °C - Allows derated operation in industrial motor drives and telecom power systems with elevated ambient temperatures. |
Pinout & Package
D2PAK (TO-263AB) package with isolated anode/cathode terminals and electrically active thermal pad (cathode). Mounting surface requires flat, smooth, greased interface for optimal RthCS = 0.5 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Input terminal for forward conduction; connects to transformer secondary or switch node in flyback/forward converters. |
| 2 | Cathode | Output terminal and thermal pad; must be soldered to large copper area or heatsink for thermal management. |
| 3 | Anode | Second anode connection - confirms dual-die configuration for enhanced current handling and redundancy. |
Key Features
| Feature | Design Value |
|---|---|
| Platinum-doped lifetime control | Enables precise trr/VF trade-off without process drift - critical for consistent EMI and efficiency across production lots. |
| 175 °C rated junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., industrial motor drives) without forced cooling. |
| Low Qrr (19 nC typ.) | Reduces energy loss during diode turn-off, lowering MOSFET voltage spikes and snubber component stress. |
| MSL Level 1 rating | Permits standard SMT reflow (peak 245 °C) without baking - simplifies manufacturing for high-volume power supply assembly. |
| Halogen-free, RoHS-compliant, Pb-free terminations | Meets global environmental compliance requirements (IEC 61249-2-21) without compromising solderability or thermal performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1502CG | 200 V VRRM, 15 A IF(AV), trr = 30 ns (typ.), but higher VF = 1.15 V @ 15 A/150 °C; TO-220AC package. | Lacks D2PAK thermal performance (RthJC = 2.5 °C/W); unsuitable for high-power density layouts requiring direct heatsink mounting. | Select STTH1502CG only if board space allows TO-220 mounting and thermal budget permits higher conduction loss. |
| IXYS MUR1520CT | 200 V VRRM, 15 A IF(AV), trr = 35 ns, but dual common-cathode configuration in TO-220AB; no D2PAK footprint. | Requires PCB redesign due to different pinout and package outline; not compatible with existing D2PAK land pattern. | Choose IXYS MUR1520CT only when dual-diode topology is required and mechanical redesign is acceptable. |
Compared with STTH1502CG and IXYS MUR1520CT, VS-MURB1520TRRPBF uniquely combines D2PAK thermal performance (RthJC = 1.5 °C/W), low VF (0.85 V), and verified 35 ns trr in a single-anode/single-cathode configuration - making it optimal for space-constrained, high-reliability SMPS where thermal management and layout continuity are critical.

FAQ
What is the maximum allowable case temperature for VS-MURB1520TRRPBF at 15 A average forward current?
The maximum allowable case temperature for VS-MURB1520TRRPBF is 150 °C at 15 A average forward current, as specified in Figure 5 of the datasheet. This limit ensures junction temperature remains within the 175 °C absolute maximum when combined with RthJC = 1.5 °C/W. Exceeding this case temperature risks thermal runaway and premature failure.
Does VS-MURB1520TRRPBF support lead-free reflow soldering per J-STD-020?
Yes, VS-MURB1520TRRPBF meets MSL Level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 245 °C. Its halogen-free, RoHS-compliant, Pb-free terminations are qualified for standard SMT processes without pre-baking, provided humidity exposure is controlled.
How does the reverse recovery charge (Qrr) of VS-MURB1520TRRPBF vary with temperature?
Qrr of VS-MURB1520TRRPBF increases with junction temperature: it is 19 nC typical at 25 °C and rises to 90 nC typical at 125 °C (per Dynamic Recovery Characteristics table). This temperature dependence must be accounted for in snubber design and EMI filtering for high-temperature operation.
Is VS-MURB1520TRRPBF pin-compatible with other D2PAK ultrafast rectifiers like STTH1502CG?
No, VS-MURB1520TRRPBF is not pin-compatible with STTH1502CG. While both use D2PAK (TO-263AB), STTH1502CG has anode-cathode-anode pinout (1-A, 2-K, 3-A), whereas VS-MURB1520TRRPBF uses anode-cathode-anode with pins 1 and 3 both anode and pin 2 cathode - confirmed by Vishay's marking diagram and pin assignment data.
What is the junction-to-ambient thermal resistance (RthJA) for VS-MURB1520TRRPBF in standard PCB layout?
The junction-to-ambient thermal resistance (RthJA) for VS-MURB1520TRRPBF is 50 °C/W under standard test conditions (JEDEC 51-2, 1 in² 2 oz Cu, 1 layer). Actual RthJA will improve significantly with larger copper areas, internal planes, or heatsink attachment - but 50 °C/W serves as the baseline for worst-case thermal modeling of VS-MURB1520TRRPBF.
