Product details
Overview
MMBZ5227BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 3.6 V ±5% Zener references with 20 mA test current, 24 Ω dynamic impedance at 20 mA, and 15 µA max reverse leakage at 1.0 V. It delivers precision voltage clamping and regulation in space-constrained power management and signal conditioning circuits.
For engineers reviewing the MMBZ5227BTS-7-F datasheet, MMBZ5227BTS-7-F pinout, MMBZ5227BTS-7-F application, or MMBZ5227BTS-7-F equivalent, key selection criteria include zener voltage tolerance (±5%), low leakage (≤15 µA @ VR = 1.0 V), thermal resistance (625 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates three electrically isolated Zener diodes in a single ultra-small SOT363 package, enabling compact multi-rail voltage reference or protection without inter-device coupling. Each diode operates independently with identical electrical specs: nominal 3.6 V zener voltage, 200 mW total power dissipation, and 1700 Ω max impedance at 0.25 mA knee current.
The triple-array architecture supports simultaneous regulation of three independent analog or digital supply rails-e.g., MCU I/O, sensor bias, and ADC reference-in automotive body control modules and industrial IoT edge nodes where board area and thermal budget are tightly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, 3.42–3.78 V range at 20 mA - ensures stable reference under production tolerance and temperature drift. |
| Power Dissipation (PD) | 200 mW - limits thermal rise to safe levels on FR4 PCBs with standard pad layout per AP02001. |
| Zener Impedance (ZZT) | 24 Ω at IZT = 20 mA - maintains tight regulation during load transients in feedback loops. |
| Reverse Leakage (IR) | ≤15 µA at VR = 1.0 V - minimizes standby current in battery-powered sensor interfaces. |
| Thermal Resistance (RθJA) | 625 °C/W - defines junction-to-ambient temperature rise under full power, critical for derating above +25°C. |
| Operating Temperature | −65 °C to +150 °C - validated for under-hood automotive and industrial environments per AEC-Q101. |
Pinout & Package

| A2 | Anode 2 | Input terminal for second Zener diode; electrically isolated from A1 and A3. |
| A3 | Anode 3 | Input terminal for third Zener diode; enables independent biasing of three analog subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-Zener array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSZ5227HT1G | Same 3.6 V nominal, but SOT-363 variant with 200 mW rating and 25 Ω ZZT; not AEC-Q101 qualified. | Lacks automotive stress validation; suitable only for commercial-grade consumer or computing applications. | Select when cost is prioritized over automotive qualification and thermal margin is sufficient. |
| BZX84-C3V6LT1G | Single 3.6 V Zener in SOT-23; 350 mW rating, 90 Ω ZZT, 5 µA IR @ 1 V - higher leakage, lower impedance, no triple integration. | Requires three devices and additional routing; increases PCB area and assembly cost. | Choose only if triple isolation is unnecessary and higher power handling is required per diode. |
Compared with NSZ5227HT1G and BZX84-C3V6LT1G, MMBZ5227BTS-7-F uniquely combines AEC-Q101 compliance, triple isolation, and 24 Ω low-impedance regulation-making it the sole option for space-constrained, automotive-qualified multi-rail voltage stabilization.

FAQ
What is the maximum continuous reverse voltage (VRWM) for MMBZ5227BTS-7-F?
The device does not specify a dedicated VRWM rating; instead, its reverse breakdown is defined by the 3.6 V zener voltage at 20 mA. The maximum non-repetitive surge power is 100 W for 1 ms pulses, and reverse leakage remains ≤15 µA at 1.0 V, confirming safe operation below 1.0 V in blocking mode.
Can MMBZ5227BTS-7-F be used in series or parallel configurations?
No-its three diodes share a common thermal die but have fully isolated anode/cathode terminals. Series connection of individual diodes is electrically possible but not recommended due to mismatched thermal coefficients; parallel use of multiple units is acceptable only with current-sharing resistors to avoid thermal runaway.
Is the SOT363 package compatible with standard reflow profiles for lead-free assembly?
Yes-the device uses matte tin finish over Alloy 42 leadframe and is qualified for Pb-free reflow per J-STD-020D Level 1 moisture sensitivity. Peak temperatures up to 260 °C are supported, and the package meets IPC/JEDEC J-STD-020 requirements for SnPb and lead-free processes.
How does the 625 °C/W thermal resistance impact layout design?
This RθJA value assumes the recommended pad layout per AP02001 (1.5 mm² copper pour per pad). To maintain TJ ≤150 °C at full 200 mW dissipation, ambient must stay ≤25 °C unless additional copper thermal vias or heatsinking are added-especially critical in sealed automotive enclosures.
