Product details

Overview

MMBZ5233BTS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array in SOT363 package, providing three isolated 6.0 V ±5% Zener references with 7 Ω dynamic impedance at 20 mA, 5.0 µA reverse leakage at 3.5 V, and 200 mW total power dissipation. It serves as precision voltage clamp and reference in low-power analog signal conditioning circuits.

For engineers reviewing the MMBZ5233BTS-7-F datasheet, MMBZ5233BTS-7-F pinout, MMBZ5233BTS-7-F application, or MMBZ5233BTS-7-F equivalent, key selection criteria include zener voltage tolerance (±5%), low dynamic impedance (7 Ω), triple-isolated topology, SOT363 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This device integrates three independent Zener diodes in a single ultra-small SOT363 package, each operating as a shunt voltage regulator with specified breakdown at 6.0 V nominal. Each diode exhibits tightly controlled Zener impedance (7 Ω at I_ZT = 20 mA) and low reverse leakage (5.0 µA max at V_R = 3.5 V), enabling stable clamping across temperature and load variations.

The triple-isolated structure eliminates inter-diode coupling, supporting independent biasing and simultaneous use in multi-rail protection or reference generation. Thermal resistance of 625 °C/W (junction-to-ambient, FR4 board) and derating curve compliance ensure reliable operation up to +150 °C ambient when power is managed per Figure 1.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage	6.0 V nominal, 5.70–6.30 V range at 20 mA - ensures ±5% regulation accuracy for 5 V system rail clamping
Zener Impedance	7 Ω at I_ZT = 20 mA - minimizes output voltage shift under varying load current
Reverse Leakage	5.0 µA max at V_R = 3.5 V - preserves low quiescent current in battery-powered sensing nodes
Power Dissipation	200 mW total (all three diodes) - supports continuous operation with thermal derating above +25 °C ambient
Package	SOT363 - 6-pin, 2.1 mm × 1.3 mm footprint compatible with high-density PCB layouts and automated assembly
Qualification	AEC-Q101 qualified - validated for automotive electronics applications requiring high-reliability discrete components

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	Input terminal for first Zener; connects to protected node or reference source
A2	Anode of Diode 2	Independent anode for second Zener; enables dual-rail clamping without shared paths
A3	Anode of Diode 3	Third isolated anode; supports triple-reference generation or redundant protection
C1	Cathode of Diode 1	Output/reference node for Diode 1; ties to regulated voltage point or ground return
C2	Cathode of Diode 2	Independent cathode path; prevents crosstalk between Diode 1 and Diode 2 operation
C3	Cathode of Diode 3	Third cathode terminal; maintains isolation integrity across all three Zeners

Key Features

Feature	Design Value

Applications

Automotive Sensor Signal Conditioning

Industrial PLC Input Protection

Use Scenario: Clamping analog sensor outputs (e.g., pressure, temperature) before ADC input in engine control units.

IC Role / Device Role / Timing Role: Shunt Zener clamp limiting transient overvoltage to ±6.3 V, protecting 12-bit SAR ADC front-end.

Use Value: Prevents ADC saturation and latch-up during load-dump events while maintaining <0.5 LSB error due to low 7 Ω impedance.

Use Scenario: Protecting 24 V digital input channels against ESD and inductive kickback in programmable logic controllers.

IC Role / Device Role / Timing Role: Three independent Zener clamps per channel group, each handling separate field-wire inputs.

Use Value: Eliminates need for six discrete diodes; reduces BOM count and layout complexity while preserving channel isolation.

USB-C Power Delivery Monitoring

Medical Wearable Battery Management

Use Scenario: Regulating and clamping CC1/CC2 line voltages and VCONN supply monitoring in USB-C PD controllers.

IC Role / Device Role / Timing Role: Dual Zener reference for CC line threshold detection and third Zener for VCONN overvoltage guardband.

Use Value: Enables single-component solution for three distinct voltage thresholds, reducing component count and improving timing consistency across lines.

Use Scenario: Providing stable 6.0 V reference for fuel gauge ICs and overvoltage cutoff in lithium-polymer battery packs.

IC Role / Device Role / Timing Role: Precision shunt reference for coulomb counter IC and independent clamp for charger feedback loop.

Use Value: Maintains ±0.3% reference stability over –40 to +85 °C, directly improving state-of-charge accuracy by 1.2%.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode array applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSZ5233B3T5G	Same 6.0 V nominal, but 10 Ω Z_ZT, higher 10 µA leakage at 3.5 V, SOT-363 package	Lower regulation precision; unsuitable for sub-10 mV error budgets	Select only if cost sensitivity outweighs impedance and leakage requirements
BZX84-C6V2-7-F	Single 6.2 V Zener, 10 Ω Z_ZT, SOT-23 package - no triple-isolation capability	Requires three devices and additional routing; increases board area and parasitic inductance	Choose only when design requires non-isolated, lower-cost single-diode implementation

Compared with NSZ5233B3T5G and BZX84-C6V2-7-F, MMBZ5233BTS-7-F delivers tighter voltage tolerance (±5% vs. ±6%), lower dynamic impedance (7 Ω vs. 10 Ω), and true triple isolation-critical for noise-sensitive multi-rail systems where cross-talk must be avoided.

FAQ

What is the maximum reverse voltage rating before breakdown for MMBZ5233BTS-7-F?

The nominal Zener voltage is 6.0 V with a guaranteed range of 5.70–6.30 V at test current I_ZT = 20 mA. Breakdown occurs within this band; the device is not rated for sustained reverse operation below 3.5 V, where reverse leakage is specified at ≤5.0 µA.

Can MMBZ5233BTS-7-F be used in parallel configurations for higher power handling?

No - the device contains three isolated Zeners in one package, but they are not internally matched for current sharing. Parallel connection of multiple MMBZ5233BTS-7-F units is not recommended due to parametric variation; thermal runaway risk exists without individual ballast resistors.

Is the SOT363 package compatible with standard reflow profiles for lead-free soldering?

Yes - the device uses matte tin finish over Alloy 42 leadframe and is qualified for JEDEC J-STD-020D Level 1 moisture sensitivity. It supports standard IPC-7095-compliant lead-free reflow profiles with peak temperatures up to 260 °C and time above liquidus of 60–90 seconds.

Does MMBZ5233BTS-7-F support bidirectional transient suppression?

No - it is a unidirectional shunt Zener diode array. For bidirectional ESD protection, external series diodes or dedicated TVS arrays (e.g., D3V3Z5U-7-F) must be used; this device operates only in reverse-biased Zener mode or forward-biased diode mode (V_F = 0.9 V @ 10 mA).
