Product details
Overview
MMBZ5236BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 7.5 V ±5% Zener references with 6 Ω dynamic impedance at 20 mA, 500 Ω at 0.25 mA, and 3.0 µA reverse leakage at 6.0 V. It delivers precision voltage regulation for low-power biasing and signal clamping in compact DC-DC feedback networks.
For engineers reviewing the MMBZ5236BTS-7-F datasheet, MMBZ5236BTS-7-F pinout, MMBZ5236BTS-7-F application, or MMBZ5236BTS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±5%), low Zener impedance at test current, thermal resistance (625 °C/W), AEC-Q101 qualification, and triple-diode integration in ultra-small SOT363.
Technical Context
This device integrates three electrically isolated Zener diodes in a single monolithic SOT363 package, each with independent anode-cathode terminals. Its design enables simultaneous voltage reference generation, overvoltage clamping, and signal-level limiting without cross-talk between channels.
Rated for 200 mW total power dissipation and operating across –65 °C to +150 °C, it supports automotive-grade reliability per AEC-Q101. The 625 °C/W junction-to-ambient thermal resistance reflects its FR4-mounted performance with recommended pad layout per AP02001.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal, 7.13–7.88 V range at IZT = 20 mA - ensures stable reference within ±5% under standard bias conditions |
| Zener Impedance (ZZT) | 6 Ω at IZT = 20 mA - minimizes output voltage variation during load transients in feedback loops |
| Reverse Leakage (IR) | 3.0 µA max at VR = 6.0 V - guarantees low standby current in high-impedance sensing nodes |
| Power Dissipation (PD) | 200 mW - defines maximum continuous DC power handling per device before thermal derating applies |
| Thermal Resistance (RθJA) | 625 °C/W - quantifies temperature rise above ambient per watt dissipated on standard FR4 PCB |
| Operating Temperature | –65 °C to +150 °C - validated for under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5-7-F | Single Zener in SOT23; 7.5 V ±5%, 15 Ω ZZT, 350 mW PD | Requires three separate placements for triple function; higher ZZT increases regulation error | Use only when board space permits discrete layout and lower impedance is not critical |
| MMBZ5236BS-7-F | Same electrical specs but SOT323 package (single-diode variant); no triple integration | Lacks channel isolation and compactness - unsuitable for multi-rail clamping or space-constrained designs | Select only if triple-diode functionality is unnecessary and SOT323 footprint is mandated |
Compared with BZX84-C7V5-7-F and MMBZ5236BS-7-F, MMBZ5236BTS-7-F uniquely delivers three matched, isolated 7.5 V Zeners in one SOT363 - reducing component count by two-thirds and improving thermal tracking between channels for tighter system-level regulation.

FAQ
What is the maximum reverse leakage current for MMBZ5236BTS-7-F at 6.0 V?
The maximum reverse leakage current is 3.0 µA at VR = 6.0 V, measured per the datasheet's Electrical Characteristics table. This value is specified at TA = +25°C and ensures minimal loading on high-impedance reference nodes in precision analog circuits.
Is MMBZ5236BTS-7-F suitable for automotive applications?
Yes - it is qualified to AEC-Q101 standards for high-reliability automotive use, with operating temperature range from –65 °C to +150 °C and full RoHS compliance. It is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces.
How does the SOT363 package affect thermal performance?
The SOT363 package has a junction-to-ambient thermal resistance of 625 °C/W when mounted on FR4 with the recommended pad layout (AP02001). This requires power derating above +25°C ambient - e.g., maximum dissipation drops to 125 mW at +75°C ambient.
Can MMBZ5236BTS-7-F replace a single Zener diode in existing designs?
Yes - any one of its three Zener elements (e.g., A1/C1 pair) can be used independently as a 7.5 V reference, with identical electrical specs to the single-diode MMBZ5236BS-7-F. Unused anodes and cathodes must be left unconnected or grounded per circuit requirements.
