Product details
Overview
BZX84C9V1S-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 9.1 V breakdown voltage, 200 mW power dissipation, and SOT-363 (SC-70) package. It regulates voltage in low-power biasing, reference, and overvoltage protection circuits, operating across –65 °C to +150 °C with ±0.5 µA max reverse leakage at 6.0 V.
For engineers reviewing the BZX84C9V1S-7-F datasheet, BZX84C9V1S-7-F pinout, BZX84C9V1S-7-F application, or BZX84C9V1S-7-F equivalent, key selection criteria include zener voltage tolerance (8.5–9.6 V), dynamic impedance (15 Ω @ 5 mA), temperature coefficient (+3.8 to +7.0 mV/°C), and ultra-small footprint for space-constrained PCBs.
Technical Context
This dual-anode Zener diode uses planar die construction for stable breakdown characteristics and low thermal resistance (625 °C/W). Its 9.1 V nominal zener voltage is specified at 5 mA test current, with 15 Ω typical zener impedance at that point and 100 Ω maximum at knee current (1 mA).
The device exhibits a positive temperature coefficient (+3.8 to +7.0 mV/°C), enabling predictable drift compensation in reference designs. It is rated for 200 mW dissipation on FR4 board with recommended pad layout and complies with RoHS and Diodes Inc.'s "Green" policy (halogen-free molding compound).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, 8.5–9.6 V range at IZT = 5 mA - defines precision of voltage reference |
| Power Dissipation (PD) | 200 mW - limits continuous regulation current to ~22 mA at 9.1 V |
| Zener Impedance (ZZT) | 15 Ω max @ 5 mA - ensures low output impedance for stable reference under load variation |
| Reverse Leakage (IR) | 0.5 µA max @ VR = 6.0 V - minimizes quiescent current in high-impedance bias networks |
| Temp Coefficient (αVZ) | +3.8 to +7.0 mV/°C @ 5 mA - enables predictable thermal drift modeling in analog references |
| Package | SOT-363 (SC-70) - 2.2 mm × 1.35 mm footprint supports high-density routing and automated assembly |
| Operating Temp | –65 °C to +150 °C - suitable for automotive under-hood and industrial control environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (NC) | No Connect | Unbonded terminal - must remain unconnected per mechanical design |
| Pin 2 (Cathode 1) | Zener Cathode (Diode 1) | Anode of first Zener connects internally to Pin 3; cathode is active regulation node |
| Pin 3 (Anode 1) | Zener Anode (Diode 1) | Reference ground connection for first Zener; reverse-biased with respect to Pin 2 |
| Pin 4 (Anode 2) | Zener Anode (Diode 2) | Shared anode path with Pin 3 - enables dual-diode topology in single package |
| Pin 5 (Cathode 2) | Zener Cathode (Diode 2) | Second independent regulation node; identical electrical specs to Pin 2 |
| Pin 6 (NC) | No Connect | Unbonded terminal - no internal connection; floating per datasheet top view |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BS-7-F | 9.1 V nominal, 350 mW PD, SOT-363, but single Zener (not dual) | Lacks dual-diode topology; higher power rating suits higher-current clamping | Select when only one Zener is needed and >200 mW dissipation is required |
| BZX84C9V1LT1G | 9.1 V nominal, 300 mW PD, SOT-23 package - larger footprint, single Zener | Not pin-compatible; different thermal resistance (RθJA = 350 °C/W vs. 625 °C/W) | Choose for legacy SOT-23 layouts where dual-diode function is unnecessary |
Compared with MMBZ5240BS-7-F and BZX84C9V1LT1G, BZX84C9V1S-7-F uniquely delivers dual 9.1 V Zeners in SOT-363 with verified 200 mW rating and 0.5 µA leakage at 6 V - optimal for space-constrained dual-reference or redundancy-critical designs.

FAQ
What is the maximum reverse leakage current for BZX84C9V1S-7-F at 6.0 V?
The maximum reverse leakage current (IR) is 0.5 µA at VR = 6.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains valid across the full operating temperature range and confirms suitability for high-impedance bias networks where leakage-induced error must be minimized.
Is BZX84C9V1S-7-F pin-compatible with other SOT-363 Zener diodes?
Yes - it uses standard SOT-363 pinout with NC-Pin1, Cathode1-Pin2, Anode1-Pin3, Anode2-Pin4, Cathode2-Pin5, NC-Pin6. However, dual-Zener functionality is not shared by all SOT-363 Zeners; verify dual-diode topology in the alternative part's datasheet before substitution.
Does this Zener diode require derating above 25 °C ambient?
Yes - power dissipation must be linearly derated above 25 °C at 0.8 mW/°C (based on RθJA = 625 °C/W). At 85 °C ambient, maximum allowable power drops to 152 mW, limiting continuous current to ~16.7 mA at 9.1 V to avoid exceeding junction temperature limits.
Can BZX84C9V1S-7-F be used in bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation. For bidirectional ESD protection, use purpose-built TVS diodes such as the D3V3M1U2LP-7 or SP1003-01UTG, which specify clamping voltage, peak pulse power, and IEC 61000-4-2 compliance.
