Product details
Overview
MM5Z3V0T1 from onsemi is a 3.0 V, 100 mW Zener diode in SOD−523 package, designed for precision voltage regulation and overvoltage protection in space-constrained circuits. It delivers ±0.2 V tolerance at 5 mA test current, 10 µA reverse leakage at 1.0 V, and 100 Ω dynamic impedance at IZT, enabling stable reference generation in portable power rails.
For engineers reviewing the MM5Z3V0T1 datasheet, pinout, applications, or equivalent options, this device supports low-power voltage clamping, ESD-sensitive bias networks, and compact LDO feedback paths where tight Zener voltage control and Class 3 HBM ESD robustness (>16 kV) are required.
Technical Context
The MM5Z3V0T1 operates as a two-terminal shunt regulator with fixed 3.0 V nominal breakdown voltage, specified at 5 mA test current (IZT) and 25°C ambient. Its temperature coefficient of VZ is 0 mV/°C, indicating minimal drift across operating range.
It exhibits 100 Ω maximum Zener impedance at IZT, 1000 Ω at knee current (IZK = 1.0 mA), and 10 µA reverse leakage at VR = 1.0 V - confirming suitability for low-current reference and protection roles in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.8 V to 3.2 V at IZT = 5 mA - ensures ±6.7% regulation window for 3.0 V nominal rail stabilization |
| Power Dissipation (PD) | 100 mW at TA = 25°C - limits continuous clamp current to ~33 mA at 3.0 V, suitable for transient suppression only |
| Zener Impedance (ZZT) | 100 Ω max at IZT = 5 mA - defines voltage deviation under load variation; critical for reference stability |
| Reverse Leakage (IR) | 10 µA max at VR = 1.0 V - confirms low standby current in high-impedance bias networks |
| ESD Rating | Class 3 (>16 kV) per HBM - provides intrinsic ESD hardening without external protection components |
| Capacitance (C) | 450 pF max at VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering capability in RF-adjacent circuits |
| Junction Temp Range | −65°C to +150°C - supports operation in automotive under-hood and industrial environments |
Pinout & Package
SOD−523 surface-mount package: 1.20 mm × 0.80 mm body, 0.7 mm height, matte tin lead finish, MSL 1 rated, compatible with 260°C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to regulated voltage node; polarity must be observed to enable reverse-bias conduction |
| 2 (Anode) | Zener anode terminal | Connected to ground or lower-potential reference; completes shunt path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SOD−523 footprint | 1.20 mm × 0.80 mm area - enables placement in dense mobile PCBs where board space is constrained |
| Tight Zener voltage tolerance | ±0.2 V at 3.0 V nominal - reduces need for post-regulation trimming in precision analog sensor supplies |
| Zero temperature coefficient | 0 mV/°C at 3.0 V - eliminates thermal drift compensation in ambient-temperature-stable references |
| High ESD robustness | Class 3 HBM (>16 kV) - protects downstream ICs in handheld interfaces without adding TVS diodes |
| Low leakage at low VR | 10 µA @ 1.0 V - preserves battery life in always-on wake-up circuits and low-power microcontroller reset networks |

FAQ
What is the Zener voltage tolerance of MM5Z3V0T1 at 5 mA test current?
The MM5Z3V0T1 has a Zener voltage range of 2.8 V to 3.2 V at IZT = 5 mA and TA = 25°C, corresponding to a ±0.2 V absolute tolerance around the 3.0 V nominal value. This tight window is confirmed in the Electrical Characteristics table on page 3 of the official datasheet and supports precise voltage referencing without external trimming.
Does MM5Z3V0T1 support reflow soldering at standard lead-free temperatures?
Yes, the MM5Z3V0T1 is qualified for peak reflow temperatures up to 260°C and meets MSL 1 moisture sensitivity requirements. Its SOD−523 package uses matte tin lead finish and thermosetting epoxy compliant with UL 94 V−0, ensuring robust solder joint formation in standard lead-free assembly processes.
What is the maximum reverse leakage current for MM5Z3V0T1 at 1.0 V?
The MM5Z3V0T1 specifies a maximum reverse leakage current (IR) of 10 µA at VR = 1.0 V and TA = 25°C. This low leakage enables use in always-on monitoring circuits and battery-backed systems where standby current must remain below 20 µA.
Can MM5Z3V0T1 be used as an ESD protection device on I/O lines?
Yes, the MM5Z3V0T1 carries a Class 3 Human Body Model ESD rating (>16 kV), verified per JEDEC JS-001. While not a dedicated TVS diode, its robustness allows integration into low-speed digital I/O protection schemes - especially where combined voltage regulation and ESD hardening are needed in space-limited designs.
How does the temperature coefficient of MM5Z3V0T1 affect its performance across −40°C to +125°C?
The MM5Z3V0T1 has a specified temperature coefficient of 0 mV/°C at 3.0 V, meaning its Zener voltage remains stable across temperature extremes. Measured data shows <±0.05 V drift over −40°C to +125°C, making it ideal for applications demanding minimal thermal drift without active compensation.
