Product details
Overview
MURS160A from Diodes Incorporated is a 1.0A, 600V surface-mount super-fast rectifier diode in SMA package, featuring 50ns reverse recovery time, 1.25V forward voltage at 1.0A, and 35A non-repetitive surge rating-used in high-frequency switching power supplies and DC-DC converters for efficient AC/DC and DC/DC energy conversion.
For engineers reviewing the MURS160A datasheet, MURS160A pinout, MURS160A application, or MURS160A equivalent, key selection criteria include its 600V peak repetitive reverse voltage, 1.0A average rectified current at TC = +130°C, 50ns tRR, 13pF junction capacitance, and RoHS-compliant lead-free matte tin terminals suitable for automated SMT assembly.
Technical Context
This super-fast rectifier employs glass-passivated die construction to ensure stable reverse leakage (5.0µA @ 25°C, 150µA @ 150°C) and thermal robustness across –55°C to +150°C operating range. Its 18°C/W junction-to-case thermal resistance supports reliable operation at high ambient temperatures when mounted on thermally optimized PCBs.
The device is optimized for high-frequency operation with low stored charge and minimal reverse recovery loss, enabling reduced switching losses in flyback, boost, and buck converters operating above 100kHz-especially where fast turn-off and low EMI are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600V - Withstands peak reverse voltage up to 600V without breakdown, enabling use in 400V DC bus and 230VAC input systems. |
| IO @ TC=130°C | 1.0A - Continuous average forward current rating at 130°C case temperature, defining thermal design margin for SMT layout. |
| tRR | 50ns - Measured under IF=0.5A/IR=1.0A/IRR=0.25A; enables high-frequency switching with low recovery loss. |
| VFM @ IF=1.0A | 1.25V - Forward voltage drop at rated current; determines conduction loss and thermal dissipation in rectification stage. |
| IFSM | 35A - Non-repetitive 8.3ms half-sine surge rating; provides immunity against inrush and transient overloads. |
| CT @ 1MHz, 4V | 13pF - Junction capacitance measured at 1MHz and 4V reverse bias; impacts high-frequency noise and snubber design. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount molded plastic case with UL 94V-0 flammability rating, cathode band polarity marking, and matte tin–plated solderable terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side of AC source or switch node; requires thermal pad connection for heat dissipation. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to output rail or positive bus; must withstand full VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast recovery time | 50ns tRR ensures minimal switching loss and EMI generation in >100kHz SMPS topologies. |
| Glass passivated die | Enhances long-term reliability and moisture resistance vs. epoxy-passivated alternatives. |
| 35A surge rating | Supports robust inrush handling in offline adapters without external current limiting. |
| Lead-free & halogen-free | Meets RoHS 3 and automotive "Green" requirements (<900ppm Br/Cl, <1000ppm Sb). |
Applications
| Switch-Mode Power Supply Rectification | Automotive DC-DC Converter Output Stage |
|---|---|

IC Role / Device Role / Timing Role: Output rectifier in synchronous or quasi-resonant topologies requiring low EMI and thermal stability. Use Value: –55°C to +150°C operating range and AEC-Q101 readiness support under-hood deployment. |

IC Role / Device Role / Timing Role: Fast recovery path for inductive energy dissipation during switching transitions. Use Value: 35A IFSM and 600V VRRM tolerate high dv/dt transients without avalanche stress or failure. | Use Scenario: Constant-current output rectification in 20–60W LED drivers for commercial lighting. IC Role / Device Role / Timing Role: Primary rectifier in isolated flyback, delivering stable DC to constant-current regulator ICs. Use Value: Low 13pF CT minimizes capacitive coupling noise into feedback loop, improving regulation accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 600V VRRM, 1.0A IO, but tRR = 75ns; higher VFM (1.3V); TO-220AC package. | Requires through-hole mounting and heatsink; less suitable for high-density SMT designs. | Prefer when board space allows TO-220 and thermal mass improves derating margin. |
| SS16 | Lower 60V VRRM, Schottky structure (no recovery time), but limited to ≤60V applications. | Not interchangeable for 400V bus systems; used only in low-voltage DC-DC outputs. | Select only for sub-60V secondary-side rectification where zero tRR is prioritized over voltage rating. |
Compared with STTH1R06 and SS16, MURS160A uniquely balances 600V capability, 50ns speed, and SMA SMT compatibility-making it optimal for compact, high-frequency, high-voltage rectification where thermal and layout constraints exclude TO-220 or Schottky-limited solutions.

FAQ
What is the maximum junction temperature for MURS160A?
The absolute maximum junction temperature is +150°C, matching its storage and operating temperature range. Derating begins at +130°C case temperature, where the average rectified current drops to 1.0A-requiring thermal design that maintains TC ≤130°C under full load.
Is MURS160A qualified to AEC-Q101?
Yes-MURS160A is manufactured in IATF 16949 certified facilities and supports PPAP documentation. While not pre-qualified as a standard part, Diodes offers AEC-Q101 qualification upon request for automotive programs with defined change control requirements.
Can MURS160A replace a standard FR107 diode?
No-FR107 has 1000V VRRM and 1.0A IO but tRR ≈ 500ns. MURS160A's 600V rating and 50ns tRR make it unsuitable for 1000V applications, though it outperforms FR107 in high-frequency efficiency where voltage margin permits.
What is the recommended PCB pad layout for SMA package?
Per Diodes' package outline (SMA DO-214AC), use minimum pad dimensions: length 6.50mm (X1), width 2.50mm (X), and thermal relief gap 1.70mm (Y). A copper pour connected to the cathode pad improves thermal dissipation and reduces RθJA by up to 15°C/W.
