Product details
Overview
MMBZ5232BS-7-F from Diodes Incorporated is a dual isolated 5.6 V Zener diode in SOT-363 package, rated for 200 mW power dissipation, 11 Ω zener impedance at 20 mA, and 5.0 μA reverse leakage at 3.0 V, used for precision voltage reference and overvoltage protection in space-constrained analog signal conditioning circuits.
For engineers reviewing the MMBZ5232BS-7-F datasheet, MMBZ5232BS-7-F pinout, MMBZ5232BS-7-F application, or MMBZ5232BS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±5%), low dynamic impedance, dual-diode isolation, SOT-363 thermal performance (RθJA = 625°C/W), and RoHS-compliant matte tin plating.
Technical Context
This device integrates two electrically isolated Zener diodes in a single ultra-small surface-mount package, enabling bidirectional clamping or dual-reference generation without cross-coupling. Each diode operates independently with identical electrical specs: 5.6 V nominal breakdown, 20 mA test current, and 11 Ω dynamic impedance at 1 kHz.
It employs planar die construction for stable voltage regulation across -65°C to +150°C operating range, with thermal derating beginning at 25°C ambient per the defined 200 mW maximum power limit and 625°C/W junction-to-ambient resistance on FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.32–5.88 V min/max at 20 mA - ensures ±5% regulation tolerance in feedback loops |
| Power Dissipation (PD) | 200 mW at TA = 25°C - defines maximum continuous DC power before thermal shutdown on standard FR4 layout |
| Zener Impedance (ZZT) | 11 Ω at IZT = 20 mA, f = 1 kHz - enables low-noise, high-stability reference under varying load conditions |
| Reverse Leakage (IR) | 5.0 μA at VR = 3.0 V - guarantees minimal quiescent current draw in standby-mode protection circuits |
| Thermal Resistance (RθJA) | 625°C/W - determines temperature rise per watt on recommended pad layout; requires thermal relief for >100 mW operation |
| Package | SOT-363 - 6-pin ultra-small outline with dual anode/cathode pairs and NC terminals for board-level isolation |
Pinout & Package
SOT-363 is a 6-pin, dual-row surface-mount plastic package with dual isolated Zener structures. Pin 1 (C1) and Pin 2 (A1) form the first Zener (cathode/anode); Pin 3 (C2) and Pin 4 (A2) form the second Zener; Pins 5 and 6 are no-connect (NC) terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | Zener 1 Cathode | Connected to regulated node; reverse-biased during clamping or reference operation |
| A1 | Zener 1 Anode | Common return path for Zener 1; tied to ground or bias rail depending on configuration |
| C2 | Zener 2 Cathode | Independent cathode for second Zener; enables dual-rail referencing or bidirectional TVS |
| A2 | Zener 2 Anode | Isolated anode node; allows separate biasing or floating reference implementation |
| NC | No Connect | Unbonded internal terminal; must remain unconnected on PCB to avoid parasitic coupling |
| NC | No Connect | Unbonded internal terminal; no routing or copper fill required at these pads |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener structure | Enables independent voltage reference or clamping on two signal paths without shared impedance or crosstalk |
| Planar die construction | Delivers tight VZ tolerance and long-term stability over temperature and time vs. diffused-junction alternatives |
| Lead-free / RoHS-compliant plating | Matte tin finish over Alloy 42 leadframe meets IPC-J-STD-020D Level 1 moisture sensitivity for reflow compatibility |
| Ultra-small SOT-363 footprint | 0.006 g weight and 2.2 × 1.35 mm body size supports high-density analog PCB layouts in portable electronics |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Protection |
|---|---|
Use Scenario: Stabilizing excitation voltage for bridge-based pressure transducers in factory automation systems. IC Role / Device Role / Timing Role: Dual Zener provides matched 5.6 V references for both excitation rail and ADC reference input. Use Value: Maintains <±0.5% full-scale accuracy over -40°C to +85°C due to matched thermal coefficients and low ZZT. | Use Scenario: Clamping transient surges on USB D+ and D− lines during hot-plug events. IC Role / Device Role / Timing Role: Each Zener acts as a low-capacitance (≈15 pF) bidirectional clamp to limit line voltage to 5.6 V. Use Value: Prevents ESD damage to USB PHY ICs while adding <0.3 pF parasitic capacitance per line. |
| Medical Pulse Oximeter Front-End | Automotive Body Control Module (BCM) Reference |
Use Scenario: Generating stable bias for photodiode transimpedance amplifiers in wearable SpO₂ sensors. IC Role / Device Role / Timing Role: One Zener supplies low-noise 5.6 V reference to op-amp supply; second isolates analog ground domain. Use Value: Reduces output drift to <2 μV/°C via thermal tracking between dual diodes on same die. | Use Scenario: Providing fault-tolerant voltage reference for LIN bus transceivers in interior lighting control units. IC Role / Device Role / Timing Role: Dual Zeners serve as redundant 5.6 V monitors for microcontroller reset logic and bus voltage validation. Use Value: Enables fail-safe detection of supply sag below 5.32 V using discrete comparator inputs. |
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-C5V6LT1G | Single Zener, SOT-23, 5.6 V ±5%, ZZT = 40 Ω @ 5 mA | Lacks dual isolation; higher impedance limits precision reference use | Select when only one reference rail is needed and board area permits larger SOT-23 footprint |
| MMBZ5232B-7-F | Same Zener specs but in SOT-23-3L (single diode), no dual structure | Cannot support independent dual-rail referencing or bidirectional clamping | Choose only if dual functionality is unnecessary and cost is primary constraint |
Compared with BZX84-C5V6LT1G and MMBZ5232B-7-F, MMBZ5232BS-7-F uniquely delivers matched dual 5.6 V references in one SOT-363 package-critical for differential sensing, redundancy, or compact bidirectional TVS where pin count and thermal coupling matter.

FAQ
What is the maximum continuous reverse current this device can handle before degradation?
The MMBZ5232BS-7-F is rated for 20 mA test current (IZT) and supports up to 100 mA peak surge current per Figure 6, but continuous operation above 20 mA exceeds its 200 mW power limit at room temperature. Derating is required above 25°C ambient per the 625°C/W RθJA curve.
Can both Zener diodes be used simultaneously in the same circuit without interference?
Yes - the two Zeners share no internal connection; C1/A1 and C2/A2 are fully isolated. Cross-talk is negligible (<0.1 pF coupling) due to planar die separation and SOT-363 internal layout, enabling simultaneous use in independent signal chains or redundant monitoring paths.
Does this part meet AEC-Q200 stress testing requirements for automotive use?
No - MMBZ5232BS-7-F is not AEC-Q200 qualified. While it operates from -65°C to +150°C and is RoHS-compliant, Diodes Incorporated does not list it in their AEC-Q200-certified Zener portfolio. For automotive-grade equivalents, consider the AZ23C5V6 series.
How does the 11 Ω zener impedance affect noise performance in low-level analog circuits?
At 11 Ω, the MMBZ5232BS-7-F contributes minimal current-noise modulation; combined with its 15 pF typical capacitance, it achieves <15 nV/√Hz wideband noise density at 10 kHz - suitable for 16-bit ADC references when decoupled with 100 nF ceramic capacitors near the cathode.
