Product details
Overview
BZX84C5V1S-7-F from Diodes Incorporated is a 5.1 V, 200 mW surface-mount Zener diode in SOT-363 package, specified at 5 mA test current with ±0.3 V tolerance (4.8–5.4 V), 60 Ω dynamic impedance at 5 mA, and −2.7 to +1.2 mV/°C temperature coefficient. It provides precision voltage regulation in low-power biasing, reference, and overvoltage protection circuits.
For engineers reviewing the BZX84C5V1S-7-F datasheet, BZX84C5V1S-7-F pinout, BZX84C5V1S-7-F application, or BZX84C5V1S-7-F equivalent, key selection criteria include zener voltage tolerance, thermal coefficient, dynamic impedance at IZT, reverse leakage at rated voltage, and SOT-363 footprint compatibility with high-density PCB layouts.
Technical Context
This dual-anode, single-cathode Zener diode uses planar die construction for stable breakdown characteristics and low leakage. Its SOT-363 package integrates two independent Zener elements sharing a common cathode terminal (Pin 3), enabling compact dual-rail referencing or redundancy in space-constrained designs.
It operates across −65 °C to +150 °C with 625 °C/W junction-to-ambient thermal resistance on FR4 board. The device is lead-free, RoHS-compliant, and manufactured with green molding compound per Diodes Inc.'s environmental policy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.1 V nominal, 4.8–5.4 V range at 5 mA - ensures stable reference within ±6% under standard bias |
| Power Dissipation (PD) | 200 mW - supports continuous regulation in low-current analog rails without heatsinking |
| Zener Impedance (ZZT) | 60 Ω at 5 mA - minimizes output voltage variation under load transients |
| Reverse Leakage (IR) | 2.0 µA max at 2.0 V - enables ultra-low standby current in battery-backed circuits |
| Temp Coefficient (αVZ) | −2.7 to +1.2 mV/°C - allows predictable drift compensation in temperature-sensitive references |
| Package | SOT-363 - 6-pin, 2.2 mm × 1.35 mm footprint with exposed pad option for thermal relief |
Pinout & Package
SOT-363 package with six terminals: two anodes (A1, A2), one shared cathode (C), and three no-connect (NC) pins. Pin 1 = A1, Pin 2 = A2, Pin 3 = C (cathode), Pins 4–6 = NC. Molded plastic case meets UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 (A1) | First Zener junction anode - connects to regulated node requiring 5.1 V reference |
| Pin 2 | Anode 2 (A2) | Second independent Zener anode - supports dual-voltage rail generation or redundancy |
| Pin 3 | Cathode (C) | Common cathode for both Zeners - ties to system ground or bias supply return |
| Pins 4–6 | No Connect (NC) | Unbonded internal terminals - must remain unconnected per mechanical design |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Enables tight VZ tolerance and repeatable breakdown behavior across production lots |
| 200 mW power rating | Supports operation up to 39 mA at 5.1 V without derating below 70 °C ambient |
| RoHS-compliant & green compound | Meets global environmental compliance without halogen or antimony-based flame retardants |
| Moisture sensitivity Level 1 | Eliminates bake requirements before reflow - compatible with standard SMT assembly lines |
Applications
| Industrial Sensor Signal Conditioning | USB-C Power Delivery Reference |
|---|---|
Use Scenario: Stabilizing excitation voltage for bridge-based pressure sensors in factory automation systems. IC Role / Device Role / Timing Role: Precision shunt reference providing 5.1 V bias to sensor Wheatstone bridge. Use Value: Maintains <±0.5% full-scale accuracy over −40 to +85 °C due to low tempco and stable ZZT. | Use Scenario: Generating accurate 5 V reference for USB PD CC line voltage detection circuitry. IC Role / Device Role / Timing Role: Zener clamp defining logic threshold for CC pin state interpretation. Use Value: Ensures reliable USB enumeration by holding reference within ±30 mV of target despite input ripple. |

Use Scenario: Monitoring Li-ion cell voltage via resistive divider into ADC, with Zener-clamped input protection. IC Role / Device Role / Timing Role: Overvoltage protector and reference limiter for ADC front-end. Use Value: Limits input to 5.4 V max while drawing only 2 µA leakage - extends battery life in sleep mode. | Use Scenario: Providing stable 5.1 V bias to CAN transceiver logic interface in 12 V automotive subsystems. IC Role / Device Role / Timing Role: Local shunt regulator isolating transceiver logic from noisy 5 V rail. Use Value: Rejects >100 mV supply noise due to 60 Ω ZZT, preventing false CAN frame errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Same SOT-363 package, 5.1 V nominal, but wider tolerance (4.8–5.4 V), higher ZZT (130 Ω), and higher IR (5 µA at 2 V) | Less suitable for low-leakage or precision biasing; acceptable for general-purpose clamping | Select when cost priority outweighs leakage or impedance performance |
| BZX84C5V1LT1G | SOT-23 package (smaller footprint), identical electrical specs, but single-Zener (no dual-anode configuration) | Cannot support dual-rail referencing; requires separate devices for redundancy | Select when board area is constrained and dual-anode functionality is unnecessary |
Compared with MMBZ5221BS-7-F and BZX84C5V1LT1G, BZX84C5V1S-7-F uniquely delivers dual-anode topology in SOT-363 with lowest ZZT and leakage among equivalents - critical for compact dual-reference or fault-tolerant designs.

FAQ
What is the maximum reverse leakage current for BZX84C5V1S-7-F at 2.0 V?
The maximum reverse leakage current is 2.0 µA at VR = 2.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains stable across −65 °C to +125 °C per thermal characterization curves, making it suitable for battery-powered systems where standby current must be minimized.
Can BZX84C5V1S-7-F be used in parallel configurations?
No - parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages causing current hogging. The dual-anode structure of this part is designed for independent use of each anode against the shared cathode, not for paralleling. For higher power, use a single higher-rated Zener or external current-sharing resistors.
Is the SOT-363 package thermally enhanced?
The standard SOT-363 package has no thermal pad; its 625 °C/W RθJA is measured on FR4 with recommended pad layout per AP02001. Thermal performance improves with copper pour under Pin 3 (cathode) and adjacent NC pads, but no internal thermal slug exists. For >150 mW sustained dissipation, consider derating above 70 °C ambient.
Does BZX84C5V1S-7-F meet AEC-Q200 for automotive use?
No - BZX84C5V1S-7-F is not AEC-Q200 qualified. While it operates from −65 °C to +150 °C and is RoHS-compliant, Diodes Inc. does not list it in their AEC-Q200 stress-tested portfolio. For automotive-grade Zener applications, consider the AZ series (e.g., AZBZX84C5V1S-7-F), which undergoes full qualification testing.
