Product details
Overview
MMBZ5240BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 10 V ±5% Zener references with 20 mA test current, 17 Ω dynamic impedance at 20 mA, and 3.0 µA max reverse leakage at 8.0 V. It delivers precision voltage regulation for low-power biasing and protection in compact DC power rails.
For engineers reviewing the MMBZ5240BTS-7-F datasheet, MMBZ5240BTS-7-F pinout, MMBZ5240BTS-7-F application, or MMBZ5240BTS-7-F equivalent, key selection criteria include zener voltage tolerance (±5%), thermal resistance (625 °C/W), triple-diode isolation, RoHS-compliant lead-free plating, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates three electrically independent Zener diodes in a single ultra-small SOT363 package, enabling space-constrained designs requiring multiple stable reference voltages without cross-coupling. Each diode operates with identical electrical specs - nominal 10 V zener voltage, 200 mW power dissipation, and 625 °C/W junction-to-ambient thermal resistance.
The triple-array architecture supports simultaneous voltage clamping or bias generation across separate signal paths. Its AEC-Q101 qualification confirms suitability for automotive electronics where thermal stability over −65°C to +150°C and robust surge immunity (per Fig. 4) are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V nominal, 9.5–10.5 V range at IZT = 20 mA - ensures tight regulation tolerance for reference-sensitive analog circuits |
| Power Dissipation (PD) | 200 mW - defines maximum continuous DC power handling on FR4 board with recommended pad layout |
| Zener Impedance (ZZT) | 17 Ω at IZT = 20 mA - indicates low dynamic resistance for stable output under varying load conditions |
| Reverse Leakage (IR) | 3.0 µA max at VR = 8.0 V - guarantees minimal standby current in high-impedance sensing or battery-backed circuits |
| Thermal Resistance (RθJA) | 625 °C/W - quantifies temperature rise per watt on standard PCB; critical for thermal derating above 25°C ambient |
| Operating Temperature | −65°C to +150°C - enables deployment in under-hood automotive, industrial control, and outdoor embedded systems |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic case (2.10 × 1.30 × 0.95 mm), UL 94V-0 rated, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Primary cathode-referenced input for first Zener; connects to regulated node or clamp point |
| A2 | Anode of Diode 2 | Independent anode for second Zener; enables dual-rail referencing or redundancy |
| A3 | Anode of Diode 3 | Third isolated anode; supports triple-voltage monitoring or multi-stage protection |
| C1 | Cathode of Diode 1 | Common reference terminal for Diode 1; tied to ground or bias rail |
| C2 | Cathode of Diode 2 | Common reference terminal for Diode 2; electrically isolated from C1 and C3 |
| C3 | Cathode of Diode 3 | Common reference terminal for Diode 3; fully isolated for independent circuit domains |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Zeners | Three independent 10 V Zener elements in one SOT363 footprint - reduces board area by ~60% vs. discrete solutions |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics - ensures long-term reliability under thermal cycling |
| Lead-free & halogen-free | Meets RoHS 2 (2011/65/EU) and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb) - supports eco-compliant manufacturing |
| Low Zener impedance | 17 Ω at 20 mA - minimizes output voltage deviation during transient load changes in precision bias networks |
| High-temperature operation | Rated up to +150°C junction temperature - suitable for under-dash or power-conversion modules without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Single 10 V Zener in SOT23; 15 Ω ZZT, 500 mW PD, no AEC-Q101 rating | Requires three devices and extra board area for same functionality; lacks automotive qualification | Select when cost-per-diode is prioritized over integration and qualification compliance |
| MMBZ5240BS-7-F | Same electrical specs but dual-diode version (SOT363); only two Zeners instead of three | Insufficient channel count for triple-reference or three-rail protection schemes | Choose only if design requires exactly two 10 V references and board space allows rework |
Compared with BZX84-C10LT1G and MMBZ5240BS-7-F, MMBZ5240BTS-7-F uniquely delivers three isolated, AEC-Q101-qualified 10 V Zeners in one SOT363 - optimizing space, reliability, and functional density for multi-rail automotive and industrial systems.

FAQ
What is the maximum reverse leakage current for MMBZ5240BTS-7-F at 8.0 V?
The maximum reverse leakage current is 3.0 µA at VR = 8.0 V and TA = +25°C, as specified in the Electrical Characteristics table. This value remains valid across the full operating temperature range per thermal derating curves in the datasheet.
Can MMBZ5240BTS-7-F be used in place of a single 10 V Zener diode?
Yes - any one of its three isolated Zener elements (e.g., A1/C1 pair) functions identically to a standalone 10 V Zener. However, using only one diode forfeits the space-saving advantage and leaves two unused, electrically isolated elements on the same die.
Is the SOT363 package compatible with standard reflow profiles for lead-free assembly?
Yes - the device is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity, with matte tin plating compatible with peak temperatures up to 260°C. Recommended pad layout is documented in Diodes' AP02001 application note.
Does MMBZ5240BTS-7-F support bidirectional transient voltage suppression?
No - it is a unidirectional Zener diode array. Each element conducts only in reverse breakdown (cathode positive relative to anode). For bidirectional TVS protection, a dedicated bipolar device such as the D3V3F1U2LP must be used.
