Product details
Overview
BZX84C3V6TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 3.6 V (nominal) Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 5 mA test current, and ±0.2 V zener voltage tolerance at 25°C - used for precision voltage clamping and reference in low-power analog sensor interfaces.
For engineers reviewing the BZX84C3V6TS-7-F datasheet, BZX84C3V6TS-7-F pinout, BZX84C3V6TS-7-F application, or BZX84C3V6TS-7-F equivalent, key selection criteria include zener voltage tolerance (±0.2 V), low dynamic impedance (90 Ω at 5 mA), thermal resistance (625 °C/W), and triple-diode isolation in ultra-small SOT-363 for space-constrained PCBs.
Technical Context
This device integrates three independent Zener diodes sharing only mechanical packaging - no internal electrical coupling - enabling simultaneous voltage regulation or clamping at multiple nodes. Each element exhibits a nominal 3.6 V breakdown with tight 3.4–3.8 V range at IZT = 5 mA and temperature coefficient of –3.5 to 0 mV/°C.
Designed for surface-mount operation on FR4 boards with specified pad layout, it delivers stable clamping under transient conditions up to 200 mW peak power, derating linearly above 25°C ambient per Fig. 1, and maintains reverse leakage ≤5.0 µA at 1.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nom) | 3.6 V - precise clamping threshold for 3.3 V rail protection and reference generation |
| Zener Voltage Range | 3.4–3.8 V @ 5 mA - ensures consistent regulation across production lots and temperature |
| Zener Impedance | 90 Ω @ 5 mA - low dynamic resistance preserves voltage stability under load variation |
| Power Dissipation | 200 mW - supports continuous clamping in low-duty-cycle surge events on compact layouts |
| Thermal Resistance | 625 °C/W - requires minimal copper area for thermal management in passive-clamp designs |
| Reverse Leakage | ≤5.0 µA @ 1.0 V - negligible standby current in battery-powered sensing circuits |
Pinout & Package
Package: SOT-363 - ultra-small plastic surface-mount case (2.2 × 1.35 × 0.9 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 1 | First Zener element anode - connects to ground or low-side clamp node |
| A2 | Anode 2 | Second Zener element anode - electrically isolated for independent circuit node |
| A3 | Anode 3 | Third Zener element anode - enables triple-rail clamping without discrete parts |
| C1 | Cathode 1 | First Zener element cathode - ties to protected signal or supply rail |
| C2 | Cathode 2 | Second Zener element cathode - supports dual-voltage reference generation |
| C3 | Cathode 3 | Third Zener element cathode - allows redundancy or multi-point ESD protection |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Zener elements | Enables three independent clamping paths in one footprint - reduces board area by ~60% vs. discrete equivalents |
| Low zener impedance (90 Ω) | Maintains <±20 mV regulation error under ±1 mA load shift - critical for ADC reference stability |
| SOT-363 package | 0.006 g mass and 2.2 × 1.35 mm outline - suitable for wearables and miniaturized IoT sensor modules |
| –3.5 to 0 mV/°C tempco | Minimizes drift-induced offset in temperature-sensitive analog front-ends (e.g., RTD interfaces) |
Applications
| Industrial Sensor Signal Conditioning | USB-C Port ESD Protection |
|---|---|
Use Scenario: Clamping differential inputs of 24-bit sigma-delta ADCs in pressure transmitters operating at –40 to +125°C ambient. IC Role / Device Role / Timing Role: Zener array provides bidirectional overvoltage protection and stable 3.6 V reference for excitation and biasing. Use Value: Tight 3.4–3.8 V tolerance and low tempco ensure <0.05% full-scale error contribution across temperature. | Use Scenario: Protecting CC1/CC2 and VCONN lines in USB-C receptacles against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Triple Zener configuration clamps all three critical lines simultaneously with matched breakdown behavior. Use Value: Isolated cathodes/anodes prevent cross-talk during fast transients; 5 µA leakage avoids false detection in low-power UFP mode. |
| Automotive Cabin Ambient Light Sensing | Medical Wearable Battery Monitoring |
Use Scenario: Stabilizing photodiode amplifier supply in AEC-Q200-compliant light sensors mounted near dashboard displays. IC Role / Device Role / Timing Role: Acts as shunt regulator for op-amp VREF, rejecting ripple from switched DC-DC converters. Use Value: 200 mW rating handles pulsed LED backlight interference; SOT-363 fits under compact lens assemblies. | Use Scenario: Providing accurate 3.6 V reference for fuel-gauge ICs monitoring Li-ion cell voltage in patch-style ECG monitors. IC Role / Device Role / Timing Role: Zener reference sets ADC full-scale range for 0–4.2 V battery measurement. Use Value: 90 Ω impedance limits reference error to <0.1 mV per 10 µA load change - essential for ±1 mV SOC accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | Single 3.6 V Zener in SOT-363, same zener voltage range but no triple-element integration | Requires three separate placements for equivalent functionality - increases layout area and assembly cost | Select when only one clamping node is needed or board real estate permits discrete placement |
| BZX84C3V6LT1G | Single 3.6 V Zener in SOT-23, identical electrical specs but different package and no multi-diode integration | Lacks isolation between elements - unsuitable for multi-rail or differential clamping | Choose for legacy SOT-23 compatibility or where triple-diode function is unnecessary |
Compared with MMBZ5227BS-7-F and BZX84C3V6LT1G, BZX84C3V6TS-7-F uniquely delivers three independent 3.6 V Zeners in one SOT-363 footprint - reducing component count, routing complexity, and thermal coupling in multi-node protection schemes.

FAQ
What is the maximum reverse voltage this device can withstand before breakdown?
The BZX84C3V6TS-7-F has a nominal zener voltage of 3.6 V with guaranteed breakdown between 3.4 V and 3.8 V at 5 mA test current. It is not rated for sustained reverse voltage above its zener range - operation beyond 3.8 V will cause conduction and power dissipation governed by the 200 mW limit and thermal derating curve.
Can this device be used for bidirectional ESD protection?
No - each Zener element is unidirectional (anode-cathode). For bidirectional protection, external series diodes or dedicated TVS arrays are required. This part provides only forward-biased clamping from cathode to anode, making it suitable for DC rail clamping or reference, not AC line protection.
Is the SOT-363 package compatible with standard reflow profiles?
Yes - the SOT-363 package is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity, supporting peak temperatures up to 260°C. Its matte tin finish ensures reliable solderability, and the 0.006 g mass minimizes thermal stress during profile ramp-up.
How does the temperature coefficient affect accuracy in precision references?
With a temperature coefficient of –3.5 to 0 mV/°C, the zener voltage drifts up to –0.35 V over a 100°C range - translating to ~10 mV error at 125°C ambient. For sub-mV reference stability, external compensation or calibration is required; this part suits applications tolerating ~0.3% full-scale drift.
