Product details
Overview
MMBZ5233BS-7-F from Diodes Incorporated is a dual isolated 6.0 V Zener diode pair in SOT-363 package, rated for 200 mW total power dissipation, 7 Ω zener impedance at 20 mA, and 5.0 μA reverse leakage at 3.5 V. It serves as precision voltage reference and overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the MMBZ5233BS-7-F datasheet, MMBZ5233BS-7-F pinout, MMBZ5233BS-7-F application, or MMBZ5233BS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±5%), low dynamic impedance, dual-diode isolation, SOT-363 footprint compatibility, and RoHS-compliant matte tin plating.
Technical Context
This dual-Zener device integrates two electrically isolated 6.0 V Zener junctions in a single ultra-small SOT-363 package, enabling bidirectional clamping or dual-rail reference generation without cross-coupling. Each diode operates independently with identical electrical specs: 20 mA test current, 7 Ω dynamic impedance at 1 kHz, and 5.0 μA leakage at VR = 3.5 V.
The planar die construction ensures stable breakdown characteristics across -65°C to +150°C operating range. Thermal resistance is 625°C/W on FR4 PCB with recommended pad layout, limiting continuous power to 200 mW at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 6.0 V nominal, 5.7–6.3 V min/max - defines precise clamping threshold for 3.3 V/5 V rail protection |
| Test Current | 20 mA - standard bias point for guaranteed Zener regulation and impedance spec |
| Zener Impedance | 7 Ω at 20 mA, 1 kHz - ensures minimal voltage deviation under load transients |
| Reverse Leakage | 5.0 μA at 3.5 V - confirms low standby current in undervoltage detection circuits |
| Power Dissipation | 200 mW total - supports dual-diode operation within thermal limits on standard PCB |
| Package | SOT-363 - 6-pin ultra-small outline enables high-density layout in space-constrained designs |
| Operating Temp | -65°C to +150°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
SOT-363 package: 6-pin, dual-isolated configuration with two independent Zener diodes sharing no internal connection. Molded plastic case meets UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | Anode of Diode 1 | Connects to cathode of external series resistor for forward-biased Zener operation |
| A1 | Cathode of Diode 1 | Provides regulated 6.0 V output when biased into breakdown |
| C2 | Anode of Diode 2 | Independent anode terminal for second Zener path; no internal link to C1 |
| A2 | Cathode of Diode 2 | Enables bidirectional clamping or dual-reference generation |
| NC | No Connect | Two unconnected pins - mechanical support only, must remain floating |
| NC | No Connect | Second unconnected pin - no electrical function; avoid routing traces |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zeners | Two independent 6.0 V Zener junctions in one SOT-363 footprint - saves board area vs. discrete pairs |
| Low dynamic impedance | 7 Ω at 20 mA - maintains tight voltage regulation during fast load steps in sensor interfaces |
| Lead-free/RoHS compliant | Matte tin finish over Alloy 42 leadframe - satisfies global environmental compliance requirements |
| High temperature rating | Operates from -65°C to +150°C - suitable for under-hood automotive and industrial motor control |
Applications
| Industrial Sensor Signal Conditioning | USB Port ESD Protection |
|---|---|
Use Scenario: Clamping analog sensor outputs (e.g., 4–20 mA transmitters) against transient overvoltage events. IC Role / Device Role / Timing Role: Dual-Zener acts as bidirectional voltage limiter on differential signal lines. Use Value: Prevents ADC input saturation and protects downstream op-amps using matched 6.0 V breakdown in both directions. | Use Scenario: Protecting USB D+ and D− data lines from electrostatic discharge up to ±15 kV. IC Role / Device Role / Timing Role: Zener pair provides low-capacitance (<2 pF typical) clamping to ground and VBUS rails. Use Value: Maintains signal integrity at 480 Mbps while meeting IEC 61000-4-2 Level 4 immunity requirements. |
| Automotive Body Control Module | Low-Power IoT Node Voltage Reference |
Use Scenario: Regulating bias voltage for LIN bus transceivers in 12 V vehicle systems. IC Role / Device Role / Timing Role: One Zener supplies stable 6.0 V reference; second used for reverse-polarity protection. Use Value: Eliminates need for separate reference IC and protection diode, reducing BOM count and cost. | Use Scenario: Providing accurate 6.0 V reference for battery-monitoring ADC in coin-cell-powered sensors. IC Role / Device Role / Timing Role: Zener operates in low-current mode (≤100 μA) to minimize quiescent power draw. Use Value: Enables <1 μA sleep-mode current while maintaining ±1% reference accuracy over temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2-7-F | Single 6.2 V Zener in SOT-23; no dual-diode integration | Requires two devices for bidirectional clamping; larger board area | Select when only unidirectional regulation is needed and cost-per-device is prioritized |
| MMBZ5234BS-7-F | 6.2 V nominal Zener (vs. 6.0 V); 7 Ω impedance same; 5.0 μA leakage at 4.0 V | Higher clamping threshold suits 3.3 V logic with tighter margin above VCC | Choose for improved noise immunity in 3.3 V systems where 0.2 V headroom is critical |
Compared with MMBZ5233BS-7-F, BZX84-C6V2-7-F increases component count and layout area but lowers unit cost, while MMBZ5234BS-7-F shifts clamping threshold upward by 0.2 V-offering better margin against 3.3 V rail overshoot without changing impedance or thermal behavior.

FAQ
What is the maximum continuous power dissipation for MMBZ5233BS-7-F?
The device is rated for 200 mW total power dissipation at 25°C ambient when mounted on an FR4 PCB with Diodes Incorporated's recommended pad layout. Derating begins linearly above 25°C at 0.32 mW/°C, reaching zero at 150°C ambient per the published derating curve.
Can both Zener diodes be used simultaneously without interference?
Yes - the two Zener diodes are fully electrically isolated within the SOT-363 package. No internal connection exists between C1/A1 and C2/A2 terminals. Each diode operates independently with identical 6.0 V breakdown characteristics and can be biased separately.
Is MMBZ5233BS-7-F suitable for bidirectional ESD protection?
Yes - its dual-anode/cathode configuration allows implementation of a low-capacitance bidirectional TVS structure. With proper PCB layout and series impedance, it meets IEC 61000-4-2 Level 4 (±15 kV contact) when used on data lines such as USB or CAN.
What does the "-7-F" suffix indicate in the part number?
The "-7-F" denotes tape-and-reel packaging: "7" specifies SOT-363 carrier tape format, and "F" indicates lead-free, RoHS-compliant matte tin plating. The full orderable part ships in reels of 3000 units with industry-standard orientation and sprocket hole spacing.
