Product details

Overview

MMBZ5236BS-7-F from Diodes Incorporated is a dual isolated 200 mW surface-mount Zener diode in SOT-363 package, with nominal zener voltage 7.5 V (min 7.13 V, max 7.88 V) at 20 mA test current, 6 Ω dynamic impedance at 20 mA, and 3.0 μA reverse leakage at 6.0 V. It serves as precision voltage reference and overvoltage clamp in low-power analog signal conditioning circuits.

For engineers reviewing the MMBZ5236BS-7-F datasheet, MMBZ5236BS-7-F pinout, MMBZ5236BS-7-F application, or MMBZ5236BS-7-F equivalent, key selection criteria include zener voltage tolerance, low dynamic impedance for regulation stability, dual-diode isolation for bidirectional clamping, and SOT-363 footprint compatibility with high-density PCB layouts.

Technical Context

This device integrates two independent Zener diodes in a single SOT-363 package, enabling symmetrical voltage clamping or dual-rail reference generation without inter-device parameter mismatch. Each diode exhibits tightly controlled zener voltage (±5% tolerance), low 6 Ω impedance at 20 mA, and guaranteed 3.0 μA leakage at VR = 6.0 V.

Thermal performance is defined by 625 °C/W junction-to-ambient resistance on FR4 board with recommended pad layout, supporting continuous operation from –65 °C to +150 °C. The planar die construction ensures stable breakdown characteristics and repeatable parametric behavior across temperature and life cycle.

Pinout & Package

SOT-363 is a 6-pin ultra-small plastic surface-mount package with dual isolated Zener diodes. Pin 1 (C1) and Pin 2 (A1) form the first Zener (cathode/anode); Pin 3 (C2) and Pin 4 (A2) form the second Zener; Pins 5 and 6 are NC (no connection).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (C1)	Zener 1 cathode	Connected to regulated node for forward-biased clamping or reverse-biased voltage reference
Pin 2 (A1)	Zener 1 anode	Reference/ground return path for first diode; electrically isolated from second diode
Pin 3 (C2)	Zener 2 cathode	Independent clamping node-enables bidirectional protection or dual-voltage referencing
Pin 4 (A2)	Zener 2 anode	Separate ground or bias path; no internal connection to A1 or other pins
Pins 5 & 6	No Connection	Unbonded terminals-must remain unconnected per mechanical design

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-Zener voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C7V5LT1G	Single 7.5 V Zener in SOT-23; no dual-diode topology; 15 Ω Z_ZT at 5 mA	Lacks bidirectional clamping capability; requires two devices for dual-rail use	Select when only one reference node is needed and board area permits discrete placement
MMBZ5236B-7-F	Same electrical specs but in SOT-23-3L package; single Zener, not dual	Cannot replace dual-isolation function; used for single-rail regulation only	Choose only if dual-diode functionality is unnecessary and SOT-23 layout already exists

Compared with BZX84-C7V5LT1G and MMBZ5236B-7-F, MMBZ5236BS-7-F uniquely delivers matched dual-Zener performance in one SOT-363 footprint-critical for space-limited bidirectional clamping where parameter tracking and thermal coupling matter.

FAQ

What is the maximum reverse voltage this device can withstand before breakdown?

The nominal zener voltage is 7.5 V with a guaranteed range of 7.13 V to 7.88 V at 20 mA test current. Breakdown occurs within this band; the device is not rated for sustained reverse operation above 7.88 V. At 6.0 V reverse bias, leakage remains ≤3.0 μA per diode.

Can both Zener diodes be used simultaneously without interference?

Yes-pins C1/A1 and C2/A2 form two fully isolated Zener junctions with no internal connection. Electrical and thermal coupling is minimized by planar die separation and independent terminal routing, enabling simultaneous use in separate signal paths.

Is this device suitable for automotive AEC-Q200 qualification?

No-MMBZ5236BS-7-F is not AEC-Q200 qualified. While it operates from –65 °C to +150 °C and meets RoHS, Diodes Incorporated does not list this part in its AEC-Q200 stress-tested portfolio. For automotive-grade dual Zeners, consider the AZ23C7V5 series.

How does the SOT-363 package affect thermal performance compared to SOT-23?

SOT-363 has higher thermal resistance (625 °C/W) than typical SOT-23 packages (~400–500 °C/W) due to smaller copper pad area and dual-die layout. Derating begins at 70 °C ambient; full 200 mW dissipation is only valid at T_A ≤ 25 °C with optimal PCB copper pour.
