Product details

Overview

MM5Z4697T1G from onsemi is a 10 V ±5% Zener voltage regulator diode in SOD−523 package, rated for 500 mW power dissipation at TL = 75°C, with 50 µA test current (IZT), 1 µA leakage current at 7.6 V reverse bias, and ESD rating >16 kV (HBM). It provides precision voltage reference and overvoltage protection in space-constrained portable electronics.

For engineers reviewing the MM5Z4697T1G datasheet, pinout, applications, or equivalent options, key selection criteria include nominal Zener voltage tolerance, thermal derating behavior, low-leakage performance at sub-breakdown bias, and SOD−523 board assembly compatibility.

Technical Context

This device operates as a two-terminal shunt voltage regulator, maintaining stable reverse breakdown voltage across its cathode–anode terminals under controlled Zener current. Its 10 V nominal regulation point falls within the positive temperature coefficient range (>5 V), exhibiting +6.5 mV/°C typical TC per onsemi characterization data.

The SOD−523 package enables high-density placement with minimal PCB footprint (1.20 × 0.80 × 0.60 mm), while its void-free thermosetting plastic case supports reflow soldering up to 260°C for 10 seconds. Junction-to-ambient thermal resistance is 250°C/W on FR−5 board.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	9.50–10.50 V @ I_ZT = 50 µA - defines tight 10 V regulation window for reference stability
Power Dissipation (P_D)	500 mW @ T_L = 75°C - sets maximum continuous thermal load on FR−5 board
Leakage Current (I_R)	≤1 µA @ V_R = 7.6 V - ensures minimal standby current in undervoltage clamp circuits
ESD Rating	Class 3 (>16 kV HBM) - supports robust handling in automated assembly and end-user environments
Junction Temp Range	−55°C to +150°C - enables operation in automotive under-hood and industrial ambient conditions
Package	SOD−523 (Case 502) - 1.20 × 0.80 × 0.60 mm surface-mount footprint for ultra-high-density layouts

Pinout & Package

SOD−523 package features a two-terminal configuration with cathode identified by a polarity band. The device is unidirectional and polarity-sensitive; incorrect orientation prevents proper Zener conduction.

1 (Banded End)	Cathode	Connected to regulated voltage node; reverse-biased terminal during Zener operation
2 (Non-banded End)	Anode	Connected to circuit ground or lower-potential rail; completes shunt regulation path

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX584C10LT1G	Same 10 V nominal, but ±5% tolerance achieved at I_ZT = 5 mA (vs. 50 µA); higher dynamic impedance	Higher power dissipation (300 mW vs. 500 mW) and larger SOT-23 package limits high-density use	Select when higher Zener current drive capability is required and board area permits SOT-23
MMSZ4697T1G	Identical electrical specs and SOD−123 package; same marking code "4T"; differs only in package outline (1.8 × 1.4 × 1.0 mm)	Compatible functionally but requires PCB land pattern revision due to 50% larger footprint and different thermal mass	Choose only if existing design uses SOD−123 or requires higher thermal margin at cost of layout change

Compared with BZX584C10LT1G and MMSZ4697T1G, the MM5Z4697T1G delivers identical 10 V regulation with lower test current sensitivity, superior board-level power density, and tighter integration into miniaturized portable systems-without compromising ESD robustness or thermal reliability.

FAQ

What is the exact Zener voltage tolerance of MM5Z4697T1G at 50 µA test current?

The MM5Z4697T1G has a guaranteed Zener voltage range of 9.50 V to 10.50 V when measured at I_ZT = 50 µA and T_L = 30°C ±1°C, corresponding to a ±5% tolerance about the 10 V nominal value. This tolerance is verified per onsemi's Electrical Characteristics table on page 3 of the official datasheet (Rev. 5, April 2026).

Can MM5Z4697T1G be used as a substitute for MM5Z4697T5G in production?

Yes, MM5Z4697T1G and MM5Z4697T5G share identical electrical specifications and SOD−523 packaging, differing only in tape-and-reel quantity (3,000 vs. 8,000 units per reel). Both carry the same "4T" device marking and meet identical AEC−Q101 qualification where applicable. No circuit or layout changes are needed for interchange.

What is the maximum allowable reverse leakage current for MM5Z4697T1G at 7.6 V bias?

The MM5Z4697T1G specifies a maximum reverse leakage current (I_R) of 1 µA when biased at V_R = 7.6 V and T_A = 25°C. This value is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet and defines the upper bound of standby current in pre-regulation or clamp-sensing configurations.

Does MM5Z4697T1G support lead-free reflow soldering processes?

Yes, MM5Z4697T1G is Pb−Free and RoHS compliant, qualified for standard lead-free reflow profiles. Its maximum soldering temperature is rated at 260°C for 10 seconds, matching IPC/JEDEC J-STD-020 requirements. The thermosetting plastic case and corrosion-resistant finish ensure reliable wetting and joint integrity.

How does the temperature coefficient of MM5Z4697T1G affect its regulation accuracy over −40°C to +85°C?

At 10 V nominal, MM5Z4697T1G exhibits a positive temperature coefficient of approximately +6.5 mV/°C. Over −40°C to +85°C, this results in a total Zener voltage shift of ~0.81 V - meaning regulation deviates from 10 V by up to ±0.4 V across that range. System designs requiring tighter stability must include compensation or operate within narrower ambient bands.
