Product details
Overview
MMBZ5241BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 11 V ±5% Zener references at 20 mA test current, with 22 Ω dynamic impedance, 2.0 µA reverse leakage at 8.4 V, and 200 mW total power dissipation. It serves as compact voltage reference and overvoltage clamp in space-constrained power management circuits.
For engineers reviewing the MMBZ5241BTS-7-F datasheet, MMBZ5241BTS-7-F pinout, MMBZ5241BTS-7-F application, or MMBZ5241BTS-7-F equivalent, key selection criteria include zener voltage tolerance (±5%), low leakage at nominal clamping voltage, thermal resistance (625 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates three electrically isolated Zener junctions in a single ultra-small SOT363 package, enabling independent voltage regulation or clamping on three signal/power rails without cross-coupling. Each diode operates with a nominal zener voltage of 11 V, specified at IZT = 20 mA, and maintains stable regulation down to IZK = 0.25 mA.
Thermal performance is defined by RθJA = 625 °C/W on FR4 PCB with recommended pad layout, and derating begins linearly above +25°C ambient per Figure 1. The device supports operation from −65°C to +150°C and is qualified to AEC-Q101 for high-reliability automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, 10.45–11.55 V range at 20 mA - ensures precise voltage reference within ±5% tolerance under standard bias |
| Zener Impedance (ZZT) | 22 Ω at 20 mA - low dynamic resistance enables stable regulation under varying load current |
| Reverse Leakage (IR) | 2.0 µA max at 8.4 V - minimal standby current preserves efficiency in low-power clamping circuits |
| Power Dissipation (PD) | 200 mW total - limits thermal rise in dense PCB layouts; requires derating above +25°C ambient |
| Package | SOT363 - 6-pin, 2.1 mm × 1.3 mm footprint ideal for automated placement and high-density routing |

Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Voltage clamping for LIN bus transceiver I/O pins exposed to load dump transients up to ±30 V. IC Role / Device Role / Timing Role: Standby Zener clamp protecting transceiver inputs during battery surge events. Use Value: 11 V breakdown prevents damage to 5 V logic interfaces while drawing only 2.0 µA at 8.4 V - no active power consumption in quiescent state. | Use Scenario: Precision reference for 12-bit ADC in 4–20 mA loop-powered pressure sensor. IC Role / Device Role / Timing Role: Stable 11 V reference source for ratiometric excitation of bridge sensors. Use Value: ±5% VZ tolerance and 22 Ω ZZT ensure <0.1% reference drift across 0–10 mA load variation. |
| USB-C Power Delivery Monitor | Smart Meter Voltage Supervisor |
Use Scenario: Overvoltage detection on VBUS line during PD negotiation phase where transient spikes exceed 20 V. IC Role / Device Role / Timing Role: Fast-response clamping element placed before USB-C controller's VBUS sense input. Use Value: Triple-diode isolation allows dedicated clamping for VBUS, CC1, and CC2 lines using single component - reduces BOM count and layout complexity. | Use Scenario: Brown-out and overvoltage supervision of microcontroller supply in utility meter with wide AC input range. IC Role / Device Role / Timing Role: Independent 11 V reference feeding comparator inputs for dual-threshold monitoring. Use Value: AEC-Q101 qualification ensures long-term stability under 150°C storage conditions typical in outdoor meter enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSZ5241B3T5G | Same 11 V nominal Zener voltage, but SOT-363 package with 15 Ω ZZT and 1.0 µA IR at 8.4 V | Lower dynamic impedance improves regulation accuracy in precision reference use cases | Select when tighter output voltage stability under load variation is required |
| BZX84-C11LT1G | Single 11 V Zener in SOT-23; no triple-isolation capability; ZZT = 20 Ω, IR = 0.1 µA at 8.4 V | Requires three separate placements and routing for equivalent functionality | Select only if board space permits discrete implementation and cost-per-channel is prioritized over assembly efficiency |
Compared with NSZ5241B3T5G and BZX84-C11LT1G, MMBZ5241BTS-7-F uniquely delivers triple isolation in one footprint with AEC-Q101 qualification - critical for automotive multi-rail protection where thermal crosstalk and qualification traceability are mandatory.

FAQ
What is the maximum reverse voltage rating before breakdown for MMBZ5241BTS-7-F?
The device has a nominal zener voltage of 11 V with a guaranteed range of 10.45 V to 11.55 V at 20 mA test current. Breakdown occurs within this band; it is not rated for continuous operation above 11.55 V in reverse bias. At 8.4 V (95% of nominal), reverse leakage is limited to 2.0 µA maximum - confirming sharp knee behavior near rated VZ.
Can MMBZ5241BTS-7-F be used in forward-bias applications?
Yes - forward voltage is specified at 0.9 V typical at 10 mA, consistent with standard silicon PN junction behavior. However, its primary design intent is reverse-bias zener operation; forward conduction is not characterized beyond VF, and no safe operating area or pulse ratings are provided for forward use.
How does the SOT363 package affect thermal performance compared to SOD-323?
SOT363 has higher thermal resistance (RθJA = 625 °C/W) than single-die SOD-323 packages (~400 °C/W), due to shared die attach and internal thermal coupling among three junctions. Derating must follow Figure 1: full 200 mW only at +25°C ambient; power drops linearly to zero at +150°C.
Is MMBZ5241BTS-7-F suitable for use in medical equipment?
No - while AEC-Q101 qualified for automotive, it lacks ISO 13485 manufacturing certification or specific life-support compliance documentation. Diodes Incorporated explicitly prohibits use in life support devices without CEO-level written approval, per their Important Notice section.
