Product details
Overview
MMBD4148PLM-7 from Diodes Incorporated is a five-element common-cathode switching diode array in a U-DFN1616-6 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It delivers low forward voltage (0.715 V at 1 mA) and low capacitance (2.0 pF at 0 V), enabling high-speed signal routing and clamping in compact power management and interface circuits.
For engineers reviewing the MMBD4148PLM-7 datasheet, MMBD4148PLM-7 pinout, MMBD4148PLM-7 application, or MMBD4148PLM-7 equivalent, key selection criteria include per-element reverse recovery timing, common-cathode topology for shared return path, thermal resistance (256 °C/W), and JEDEC-qualified reliability for industrial and automotive-adjacent designs.
Technical Context
This device integrates five independent silicon switching diodes with a shared cathode terminal, configured for parallel signal conditioning or multi-rail protection. Its U-DFN1616-6 package supports high-density PCB layouts while maintaining thermal performance via exposed center pad soldering.
The diode array operates across –55 °C to +150 °C, with leakage current limited to 1.0 μA at 75 V and 25 nA at 20 V, and exhibits stable capacitance (≤2.0 pF) up to 1 MHz - critical for ESD-tolerant data line clamping and high-frequency logic-level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VRWM) | 75 V - defines maximum continuous DC blocking capability per element without breakdown |
| Forward Voltage (VF) | 0.715 V @ 1 mA - enables low-loss biasing and level-shifting in 3.3 V/5 V logic interfaces |
| Reverse Recovery Time (tRR) | 4.0 ns - supports >100 MHz switching in pulse shaping and high-speed sampling circuits |
| Total Capacitance (CT) | 2.0 pF @ 0 V - minimizes signal distortion in RF detector and clock buffer applications |
| Thermal Resistance (RθJA) | 256 °C/W - requires controlled copper pour and center-pad soldering for sustained 300 mA operation |
| Operating Temperature | –55 °C to +150 °C - qualified for under-hood and industrial control environments |
Pinout & Package
Package: U-DFN1616-6 - 1.6 mm × 1.6 mm, 0.5 mm pitch, 6-terminal sub-miniature plastic package with exposed thermal pad (center pin). Pin 1 marked by dot; polarity confirmed by center pad notch and internal common-cathode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Anodes (A1–A5) | Five independent input terminals; each connects to separate signal or supply rail requiring clamping or steering |
| 6 + Center Pad | Common Cathode (K) | Shared output node; must be soldered to large copper area for thermal and electrical return path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Five-diode integration | Reduces board space by >70% vs. discrete SOT-23 diodes in multi-rail protection schemes |
| Low VF at low current | 0.715 V @ 1 mA enables accurate threshold detection in battery-monitoring comparators |
| JEDEC-qualified reliability | Meets AEC-Q stress test baselines for high-reliability industrial use without automotive qualification |
| Green molding compound | UL 94V-0 rated, halogen/antimony-free formulation meets IPC-J-STD-020 moisture sensitivity Level 1 |
Applications
| USB Data Line Protection | Multi-Rail Power Sequencing |
|---|---|
Use Scenario: Clamps ESD transients on USB 2.0 D+/D− lines during hot-plug events while preserving signal integrity. IC Role / Device Role / Timing Role: Per-line transient voltage suppressor with <2.0 pF loading and sub-5 ns response. Use Value: Prevents PHY damage without degrading 480 Mbps eye diagram margin due to ultra-low capacitance and fast tRR. | Use Scenario: Controls startup order of 1.8 V, 3.3 V, and 5 V rails in FPGA or SoC power domains using diode-OR steering. IC Role / Device Role / Timing Role: Five-anode common-cathode array provides isolated enable paths with matched VF drift. Use Value: Eliminates need for five discrete diodes, reducing layout complexity and ensuring consistent turn-on timing across rails. |
| Digital Logic Level Translation | High-Frequency Clock Signal Clamping |
Use Scenario: Bi-directional level shifting between 1.8 V microcontroller I/O and 3.3 V peripheral interfaces. IC Role / Device Role / Timing Role: Passive translator using forward-biased diode drop to offset voltage thresholds. Use Value: Achieves <1 ns propagation skew across five channels, supporting SPI and I²C bus expansion without added delay. | Use Scenario: Protects clock inputs of ADCs and FPGAs from overshoot/undershoot in 100+ MHz reference distribution networks. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp placed directly at IC pin. Use Value: Maintains jitter <1 ps RMS by limiting dynamic impedance variation with 4.0 ns tRR and stable CT. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54CW-7-F | Single-pair dual-diode (2 anodes, 1 cathode); 30 V VRWM, 0.24 pF CT | Limited to two-channel clamping; insufficient for 5-rail systems | Select when only two signals require protection and ultra-low capacitance is prioritized over channel count |
| NSR0230P2T5G | Single Schottky diode; 30 V VRWM, 0.25 pF CT, no common-cathode array | Requires five separate placements; increases layout area and thermal mismatch risk | Choose for highest-frequency RF clamping where per-element isolation outweighs integration benefits |
Compared with BAT54CW-7-F and NSR0230P2T5G, the MMBD4148PLM-7 uniquely balances five-channel density, 75 V blocking, and sub-5 ns switching - making it optimal for space-constrained multi-rail digital systems where shared cathode return simplifies grounding and reduces parasitic inductance.

FAQ
What is the thermal pad connection requirement for MMBD4148PLM-7?
The center thermal pad (Pin 6) must be soldered to a minimum 25 mm² copper area with ≥4 thermal vias (0.3 mm diameter) to achieve the specified 256 °C/W RθJA. Leaving the pad unconnected raises junction temperature by >40 °C at 300 mA, risking premature failure.
Can MMBD4148PLM-7 replace discrete 1N4148 diodes in existing designs?
Yes, but only if the layout accommodates the U-DFN1616-6 footprint and the circuit uses a common-cathode topology. Each anode maps to one 1N4148 anode, but the shared cathode eliminates five separate cathode traces - requiring schematic and PCB revision for netlist compatibility.
Is MMBD4148PLM-7 qualified for automotive applications?
No - it is JEDEC-qualified for high reliability but not AEC-Q200 certified. For automotive use, Diodes offers the Q-suffix variant MMBD4148PLM-Q, which undergoes PPAP, IATF 16949 manufacturing, and full AEC-Q200 stress testing.
How does leakage current change at elevated temperature?
At +150 °C and 75 V reverse bias, leakage rises to 50 μA (vs. 1.0 μA at 25 °C), per datasheet Note 6. This is within specification but must be accounted for in high-impedance sensing nodes where >10 μA error would affect accuracy.
