Product details
Overview
MMBZ5240BS-7-F from Diodes Incorporated is a dual isolated 10 V, 200 mW surface-mount Zener diode in SOT-363 package, with nominal zener voltage 10.0 V (min 9.5 V, max 10.5 V), test current 20 mA, and zener impedance 17 Ω at IZT; used for precision voltage reference and overvoltage protection in compact power management circuits.
For engineers reviewing the MMBZ5240BS-7-F datasheet, MMBZ5240BS-7-F pinout, MMBZ5240BS-7-F application, or MMBZ5240BS-7-F equivalent, key selection criteria include zener voltage tolerance (±5%), low dynamic impedance (17 Ω @ 20 mA), dual-diode isolation, SOT-363 thermal resistance (625 °C/W), and RoHS-compliant lead-free plating.
Technical Context
This dual-Zener device integrates two electrically isolated 10 V zener junctions in a single ultra-small SOT-363 package, enabling independent voltage clamping or reference functions on adjacent signal/power rails without crosstalk. Its planar die construction ensures stable breakdown characteristics across temperature.
Designed for automated SMT assembly, it supports reflow profiles compliant with J-STD-020D Level 1 moisture sensitivity, with thermal performance validated on FR4 PCB using Diodes Inc.'s recommended pad layout. Reverse leakage remains ≤3.0 μA at 8.0 V, supporting low-power biasing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V nominal, 9.5–10.5 V range at 20 mA - defines precise clamping threshold for 3.3 V/5 V rail protection |
| Power Dissipation (PD) | 200 mW - limits continuous dissipation to avoid thermal runaway on standard FR4 layouts |
| Zener Impedance (ZZT) | 17 Ω @ 20 mA - ensures minimal voltage shift under load variation in feedback or reference paths |
| Reverse Leakage (IR) | ≤3.0 μA @ 8.0 V - enables use in high-impedance sensing nodes without loading error |
| Thermal Resistance (RθJA) | 625 °C/W - requires careful copper pour design to maintain TJ < 150 °C at full power |
| Package | SOT-363 - 6-pin, dual-diode configuration with C1/A1/C2/A2/NC/NC pinout for board-level isolation |
Pinout & Package
SOT-363 is a 6-pin ultra-small plastic surface-mount package with dual isolated anode-cathode pairs and two no-connect terminals. Pin assignment follows standardized top-view orientation per Diodes Inc. DS31039 Rev. 15-2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | Cathode of Zener 1 | Primary clamping node for first 10 V reference path; connects to protected rail |
| A1 | Anode of Zener 1 | Return path for Zener 1; ties to ground or bias source |
| C2 | Cathode of Zener 2 | Independent clamping node for second 10 V function; electrically isolated from C1 |
| A2 | Anode of Zener 2 | Separate return for Zener 2; enables dual-rail referencing without shared impedance |
| NC | No Connect | Internally unconnected terminal; must remain floating per datasheet |
| NC | No Connect | Second internally unconnected terminal; no PCB trace or solder required |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener junctions | Enables independent voltage regulation/clamping on two circuits within one footprint, reducing board area by ~40% vs. discrete dual-SOD-323 solution |
| 200 mW power rating | Supports transient suppression up to 20 mA sustained current while maintaining <1% VZ drift over temperature |
| 17 Ω dynamic impedance | Minimizes output voltage variation under ±5 mA load changes in analog reference designs |
| Lead-free / RoHS-compliant | Meets IPC-J-STD-020D Level 1 reflow requirements and EU Directive 2011/65/EU without post-process cleaning |
Applications
| Industrial Sensor Signal Conditioning | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Protecting 10-bit ADC input stages from ESD-induced overvoltage during field deployment in factory automation sensors. IC Role / Device Role: Dual-Zener provides rail-to-rail clamping (VCC and GND) while isolating analog front-end from digital noise coupling. Use Value: 9.5–10.5 V tolerance ensures clamp activates before 12 V transients damage 3.3 V ADC inputs; dual isolation prevents ground bounce propagation. | Use Scenario: Safeguarding CC line voltage levels in USB-C PD controllers against bus voltage overshoot during hot-plug events. IC Role / Device Role: One Zener clamps CC-to-GND, the other clamps CC-to-VCONN, maintaining differential integrity under ±20 V surges. Use Value: 17 Ω ZZT ensures clamp voltage stays within ±0.1 V of 10 V during 100 ns transients, meeting USB-IF v2.1 compliance margin. |
| Low-Power IoT Node Reference | Automotive Body Control Module Clamp |
Use Scenario: Generating stable 10 V reference for lithium battery monitoring ICs in energy-harvesting wireless sensor nodes. IC Role / Device Role: Zener 1 supplies reference to ADC, Zener 2 biases comparator hysteresis - both share thermal environment but remain electrically decoupled. Use Value: ≤3.0 μA leakage at 8 V allows operation from 10 μA supply rails; dual structure eliminates need for separate decoupling capacitors. | Use Scenario: Clamping LIN bus transceiver I/O pins against load-dump spikes in 12 V automotive body control modules. IC Role / Device Role: One Zener protects LIN TX, the other protects LIN RX - isolation prevents fault propagation between transmit/receive paths. Use Value: 200 mW rating sustains 100 ms load-dump pulses per ISO 7637-2 Pulse 5a; SOT-363 footprint fits tight CAN/LIN co-location layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Single 10 V Zener, SOT-23, 350 mW, ZZT = 20 Ω @ 5 mA | Requires two devices for dual-rail use; higher power but larger footprint and no inherent isolation | Prefer when higher power margin is needed and board space permits duplication |
| PDZ10B,115 | Single 10 V Zener, SOT-323, 250 mW, ZZT = 15 Ω @ 5 mA, tighter 5% tolerance | Lacks dual-diode integration; no electrical isolation between instances | Choose for cost-sensitive single-clamp designs where isolation is not required |
Compared with BZX84-C10LT1G and PDZ10B,115, MMBZ5240BS-7-F uniquely delivers two isolated 10 V references in one SOT-363, reducing component count and interconnect inlays while maintaining matched thermal tracking - critical for precision dual-rail systems.

FAQ
What is the maximum reverse leakage current for MMBZ5240BS-7-F at 8.0 V?
The maximum reverse leakage current is 3.0 μA at VR = 8.0 V, measured at TA = 25°C per DS31039 Rev. 15-2. This value remains stable up to +125°C, making it suitable for low-bias reference circuits where leakage-induced offset must be minimized.
Can MMBZ5240BS-7-F be used in place of a single 10 V Zener diode?
Yes - either Zener junction (C1/A1 or C2/A2) can operate independently as a standalone 10 V reference. The unused pair must have both terminals left unconnected; NC pins must remain floating. Thermal coupling between junctions is minimal due to planar die separation.
Is the SOT-363 package compatible with standard reflow soldering processes?
Yes - MMBZ5240BS-7-F meets J-STD-020D Level 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. Diodes Inc. specifies ramp rates and time-above-liquidus per their AP02001 guideline, and the matte tin finish ensures reliable wetting on OSP- and ENIG-finished PCBs.
How does the 17 Ω zener impedance affect circuit stability in feedback loops?
At 20 mA test current, 17 Ω impedance means a 1 mA load change induces only 17 mV output shift - critical for stabilizing op-amp feedback networks or ADC reference buffers. Lower ZZT than alternatives like BZX84-C10LT1G (20 Ω @ 5 mA) improves regulation under dynamic loads.
