Product details
Overview
MMBZ5230BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 4.7 V ±5% Zener references with 19 Ω dynamic impedance at 20 mA, 5 µA reverse leakage at 2.0 V, and 200 mW power dissipation. It serves as precision voltage clamp and reference in low-power analog monitoring circuits.
For engineers reviewing the MMBZ5230BTS-7-F datasheet, MMBZ5230BTS-7-F pinout, MMBZ5230BTS-7-F application, or MMBZ5230BTS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±5%), low leakage at VR = 2.0 V, thermal resistance (625 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates three independent Zener diodes in a single ultra-small SOT363 package, each with identical electrical characteristics and fully isolated anode-cathode paths. Its design supports simultaneous voltage regulation or clamping across multiple signal rails without cross-talk.
The Zener operates with a test current of 20 mA (IZT), exhibits 19 Ω impedance at IZT and 1900 Ω at knee current (0.25 mA), and maintains stable breakdown behavior down to 5 µA reverse leakage at 2.0 V - enabling use in battery-backed or low-quiescent-current systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.7 V nominal, 4.47–4.94 V range at 20 mA - ensures tight voltage reference for analog sensing and ADC biasing |
| Zener Impedance (ZZT) | 19 Ω at 20 mA - minimizes output voltage variation under load changes in regulation circuits |
| Reverse Leakage (IR) | 5.0 µA max at VR = 2.0 V - enables reliable operation in low-power standby modes |
| Power Dissipation (PD) | 200 mW at TA = 25°C - defines maximum continuous DC power handling on standard FR4 PCB |
| Thermal Resistance (RθJA) | 625 °C/W - determines junction temperature rise per milliwatt in typical surface-mount layout |
| Operating Temperature | −65°C to +150°C - supports deployment in under-hood automotive and industrial environments |

Applications
| Automotive Sensor Signal Conditioning | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Clamping differential inputs of automotive oxygen or pressure sensors against transients during load dump events. IC Role / Device Role / Timing Role: Zener array provides rail-to-rail overvoltage protection for op-amp front-end stages without adding parasitic capacitance. Use Value: 19 Ω ZZT ensures minimal voltage shift during 100 ns surge pulses; AEC-Q101 rating guarantees operation across −40°C to +125°C ambient. | Use Scenario: Protecting 4–20 mA current loop receiver inputs from ESD and inductive kickback in factory automation cabinets. IC Role / Device Role / Timing Role: Each Zener leg independently clamps positive/negative signal lines and supply rail, preventing latch-up in precision ADCs. Use Value: Triple isolation eliminates ground-loop coupling; 5 µA leakage avoids loading high-impedance current-sense resistors. |
| Portable Medical Device Reference | Consumer IoT Battery Monitoring |
Use Scenario: Providing stable 4.7 V reference for ADC calibration in handheld pulse oximeters and glucose meters. IC Role / Device Role / Timing Role: Functions as precision shunt reference in low-current, battery-powered measurement chains. Use Value: Tight 4.47–4.94 V tolerance and low tempco (implied by AEC-Q101 stability) ensure <0.5% full-scale error over operating range. | Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles in smart home sensors with coin-cell backup. IC Role / Device Role / Timing Role: Acts as undervoltage lockout (UVLO) threshold detector via comparator input biasing. Use Value: 200 mW rating allows brief overvoltage absorption during hot-plug events; SOT363 footprint fits sub-5 mm² PCB real estate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSZ5230B3T5G | Same 4.7 V nominal, but 22 Ω ZZT and 10 µA IR at 2.0 V; SOT-363, AEC-Q101 qualified | Higher leakage limits use in ultra-low-power sleep modes; slightly higher impedance affects regulation accuracy | Select when cost sensitivity outweighs leakage or impedance requirements |
| BZX84-C4V7LT1G | Single 4.7 V Zener in SOT-23; 20 Ω ZZT, 5 µA IR; not AEC-Q101 qualified | Requires three separate placements; lacks integrated triple isolation and automotive qualification | Choose only for non-automotive, space-tolerant designs where layout flexibility is prioritized |
Compared with NSZ5230B3T5G and BZX84-C4V7LT1G, MMBZ5230BTS-7-F delivers lower leakage, tighter Zener tolerance, and guaranteed triple-isolation in one AEC-Q101-qualified package - making it optimal for space-constrained, safety-aware automotive and industrial signal conditioning.

FAQ
What is the maximum reverse voltage (VR) at which leakage current is specified for MMBZ5230BTS-7-F?
The datasheet specifies maximum reverse leakage current (IR) of 5.0 µA at VR = 2.0 V. This value is measured under standard conditions (TA = +25°C) using short-duration pulse testing to minimize self-heating effects. It is not rated for continuous operation above this voltage without considering power derating curves.
Can MMBZ5230BTS-7-F be used in place of a single Zener diode like BZX584-C4V7?
No - MMBZ5230BTS-7-F contains three isolated Zener diodes in one SOT363 package, each with its own anode and cathode terminals. It cannot substitute for a single-diode package without redesigning the PCB layout and verifying that all three Zeners are utilized or properly terminated to avoid unintended conduction paths.
Is the SOT363 package of MMBZ5230BTS-7-F compatible with standard reflow profiles for lead-free soldering?
Yes - the device uses matte tin finish over Alloy 42 leadframe and is rated for lead-free reflow. Its moisture sensitivity level is 1 per J-STD-020D, meaning it can be stored indefinitely at ≤30°C/60% RH without baking. Standard IPC/JEDEC J-STD-020-compliant peak reflow temperatures up to 260°C are supported.
Does MMBZ5230BTS-7-F have a specified Zener voltage temperature coefficient?
No explicit temperature coefficient (TC) value is provided in the DS30184 datasheet. However, its AEC-Q101 qualification implies stable performance across −65°C to +150°C, and typical Zener TC for this voltage range (4.7 V) falls between +2 mV/°C and +4 mV/°C. For precision applications, system-level characterization across temperature is recommended.
