Product details

Overview

MM3Z36VC from onsemi is a 36 V ±5% tolerance Zener diode in SOD−323FL package, rated for 200 mW power dissipation, with 84 Ω zener impedance at 2 mA test current, used for precision voltage regulation and reference in low-power analog circuits.

For engineers reviewing the MM3Z36VC datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, dynamic impedance at specified test current, maximum regulator current, thermal resistance, and RoHS-compliant matte tin finish.

Technical Context

This device operates as a reverse-biased voltage reference with nominal V_Z = 36 V (min 34.2 V, max 37.8 V) at I_ZT = 2 mA, exhibiting 84 Ω zener impedance (Z_ZT) under those conditions and 329 Ω impedance (Z_ZK) at knee current I_ZK = 0.5 mA.

It features a maximum junction temperature of 150 °C, thermal resistance R_JA = 595 °C/W on minimum PCB land pad, and forward voltage ≤1.0 V at 10 mA - confirming suitability for bidirectional clamping and low-current biasing applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_Z @ I_ZT	34.2 V to 37.8 V at 2 mA - defines stable regulation window for feedback or reference use
Z_ZT	84 Ω - low dynamic impedance ensures minimal output voltage variation under load changes
P_D	200 mW - limits continuous power handling; requires thermal derating above 25 °C ambient
R_JA	595 °C/W - high thermal resistance necessitates careful PCB copper area planning for reliability
I_R @ V_R	45 nA max at 25.2 V - confirms low leakage in sub-zener bias conditions
Package	SOD−323FL - 1.7 mm × 1.25 mm × 0.95 mm ultra-thin SMD footprint for space-constrained designs

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-B36	Same 36 V ±5%, but in SOD-323 package (not FL variant); R_JA = 625 °C/W	Slightly higher thermal resistance; identical electrical specs for most low-power uses	Preferred where legacy SOD-323 footprint compatibility is required over thin-profile optimization
MMSZ4687	36 V ±5%, SOD-123 package; P_D = 500 mW; Z_ZT = 50 Ω at 5 mA	Higher power rating and lower impedance, but larger footprint and different test current	Chosen when higher current capability or tighter regulation under variable loads is needed

Compared with MM3Z36VC, BZX384-B36 offers identical voltage spec in a marginally less thermally efficient package, while MMSZ4687 trades miniaturization for higher power handling and lower dynamic impedance - guiding selection based on board space versus thermal or regulation performance priorities.

FAQ

What is the nominal zener voltage and tolerance of MM3Z36VC?

The MM3Z36VC has a nominal zener voltage of 36 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 34.2 V and 37.8 V when tested at I_ZT = 2 mA. This tolerance is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 3, August 2023), and applies specifically to the MM3Z36VC variant within the MM3Z2V4C–MM3Z75VC family.

What package type does MM3Z36VC use, and what are its key mechanical dimensions?

MM3Z36VC uses the SOD−323FL package (Case 477AB), measuring 1.7 mm × 1.25 mm × 0.95 mm with a matte tin finish. This ultra-thin, lead-free package is optimized for high-density PCB layouts and complies with RoHS Directive 2011/65/EU. The marking "ZV" identifies the MM3Z36VC device on the cathode side of the package.

What is the maximum power dissipation and thermal resistance of MM3Z36VC?

MM3Z36VC has a maximum power dissipation (P_D) of 200 mW at T_A = 25 °C and a junction-to-ambient thermal resistance (R_JA) of 595 °C/W when mounted on a PCB with minimum land pad. Derating is required above 25 °C ambient - for example, usable power drops to ~120 mW at 70 °C ambient - as specified in the Absolute Maximum Ratings table of the onsemi datasheet.

How does the zener impedance of MM3Z36VC affect its regulation performance?

MM3Z36VC exhibits a zener impedance (Z_ZT) of 84 Ω at I_ZT = 2 mA, directly impacting output voltage stability under varying load currents. A lower Z_ZT yields smaller ΔV_Z for a given ΔI_Z; for instance, a 1 mA load shift causes ~84 mV change in regulated voltage. This value is measured using 60-Hz AC superimposed on DC bias, per onsemi's test methodology in the datasheet.

Is MM3Z36VC suitable for bidirectional voltage clamping applications?

Yes, MM3Z36VC supports bidirectional clamping: in forward bias, it conducts with V_F ≤ 1.0 V at I_F = 10 mA; in reverse bias, it regulates at ~36 V. Its low reverse leakage (≤45 nA at 25.2 V) prevents interference during normal signal operation, making it effective for protecting sensitive inputs against both positive and negative transients - a capability verified in the Electrical Characteristics and Typical Performance sections of the onsemi datasheet.
