Product details
Overview
MM5Z7V5T1 from onsemi is a 7.5 V ±0.4 V Zener diode in SOD−523 package, rated for 100 mW steady-state power dissipation, with 15 Ω maximum Zener impedance at 5 mA test current and 1 µA reverse leakage at 5.0 V, used for precision voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM5Z7V5T1 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, mechanical dimensions, ESD robustness (Class 3, >16 kV HBM), and real-world use context for board-level voltage reference and clamping design.
Technical Context
This Zener regulator operates in reverse breakdown mode with a nominal 7.5 V regulation point at IZT = 5 mA, exhibiting low dynamic impedance (ZZT ≤ 15 Ω) and tight voltage tolerance (±0.4 V). Its temperature coefficient of +2.5 mV/°C ensures predictable drift across −65°C to +150°C junction range.
The device features ultra-small SOD−523 footprint (1.20 mm × 0.80 mm × 0.70 mm), matte tin lead finish, UL 94 V−0 compliant epoxy case, and MSL 1 reflow rating up to 260°C - enabling high-density placement on handheld PCBs without thermal derating concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.0 V min / 7.5 V nom / 7.9 V max @ IZT = 5 mA - defines stable regulation band for reference or clamp circuits |
| Power Dissipation (PD) | 100 mW @ TA = 25°C - sets maximum continuous power handling on FR-5 board |
| Zener Impedance (ZZT) | ≤15 Ω @ IZT = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤1 µA @ VR = 5.0 V - guarantees low quiescent current in standby or sensing paths |
| ESD Rating | Class 3 (>16 kV) per HBM - supports robust handling in automated assembly and end-user environments |
| Junction Temp Range | −65°C to +150°C - enables operation in automotive cabin, industrial edge, and battery-powered devices |
| Capacitance (C) | 140 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent layouts |
Pinout & Package
SOD−523 surface-mount package: 2-terminal, ultra-compact plastic case (1.20 mm × 0.80 mm × 0.70 mm), cathode marked with band, void-free thermosetting epoxy meeting UL 94 V−0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Regulated Output Node | Connected to voltage rail being stabilized; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference Ground Node | Tied to system ground or return path; establishes reference potential for Zener breakdown operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Small Footprint | SOD−523 outline (1.20 mm × 0.80 mm) saves >60% board area vs. SOD-123 - critical for smartphone camera modules and wearables |
| Precision Voltage Regulation | ±0.4 V tolerance at 7.5 V enables accurate 3.3 V LDO biasing or ADC reference scaling without trimming |
| Low Dynamic Impedance | ZZT ≤ 15 Ω minimizes output ripple under 1–10 mA load shifts - suitable for sensor supply rails |
| High ESD Robustness | Class 3 HBM (>16 kV) eliminates need for external TVS in USB port or button interface protection |
| MSL 1 Reflow Compatibility | Rated for peak 260°C reflow without preconditioning - supports single-pass assembly in high-volume manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C7V5 | Same 7.5 V nominal, but SOD-323 package (1.7 mm × 1.3 mm); ZZT = 20 Ω @ 5 mA; 200 mW rating | Larger footprint allows higher power handling but occupies ~2.5× more board area than MM5Z7V5T1 | Select when thermal margin >100 mW is required and PCB space permits larger device |
| MMSZ5236B | SOD-123 package (3.7 mm × 1.6 mm); 7.5 V nominal; ZZT = 19 Ω @ 20 mA; 500 mW rating | Higher power capability and lower impedance at higher current, but incompatible with ultra-dense layouts | Choose for industrial control boards where 500 mW surge tolerance outweighs miniaturization needs |
Compared with BZX584-C7V5 and MMSZ5236B, the MM5Z7V5T1 delivers optimal trade-off between board-area efficiency (SOD−523), low-impedance regulation (15 Ω), and ESD resilience (>16 kV), making it preferred for consumer portables where size and reliability are jointly constrained.

FAQ
What is the Zener voltage tolerance of MM5Z7V5T1 at 25°C?
The MM5Z7V5T1 has a Zener voltage specification of 7.0 V minimum, 7.5 V nominal, and 7.9 V maximum at IZT = 5 mA and TA = 25°C. This ±0.4 V tolerance band ensures predictable regulation behavior for precision reference and clamping functions in the MM5Z7V5T1 design.
Can MM5Z7V5T1 be used in place of a 7.5 V Zener diode in an SOD-123 footprint?
No - the MM5Z7V5T1 uses the smaller SOD−523 package (1.20 mm × 0.80 mm), while SOD-123 measures 3.7 mm × 1.6 mm. Direct replacement requires PCB layout revision. The MM5Z7V5T1 is not pin-compatible with SOD-123 devices due to different pad geometry and terminal spacing.
What is the maximum reverse leakage current for MM5Z7V5T1 at 5.0 V?
The MM5Z7V5T1 exhibits a maximum reverse leakage current (IR) of 1 µA when biased at VR = 5.0 V and TA = 25°C. This low leakage supports energy-sensitive applications such as battery-backed real-time clocks and always-on sensor nodes using the MM5Z7V5T1.
Does MM5Z7V5T1 meet JEDEC MSL 1 requirements?
Yes - the MM5Z7V5T1 is qualified for MSL 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions and subjected to peak reflow temperatures up to 260°C without preconditioning. This simplifies handling and assembly for the MM5Z7V5T1 in high-volume SMT lines.
What is the temperature coefficient of MM5Z7V5T1's Zener voltage?
The MM5Z7V5T1 has a specified temperature coefficient of +2.5 mV/°C for its Zener voltage over the operating junction temperature range. This positive drift characteristic helps compensate for other negative-coefficient components in mixed-signal systems using the MM5Z7V5T1 as a reference node.
