Product details
Overview
BZX84C10S-7-F from Diodes Incorporated is a dual 200 mW surface-mount Zener diode in SOT-363 package, rated for nominal 10 V zener voltage (9.4–10.6 V at 5 mA), with 20 Ω max zener impedance and 0.2 µA max reverse leakage at 7 V, used for precision voltage regulation and overvoltage protection in compact power management circuits.
For engineers reviewing the BZX84C10S-7-F datasheet, BZX84C10S-7-F pinout, BZX84C10S-7-F application, or BZX84C10S-7-F equivalent, key selection criteria include zener voltage tolerance, thermal resistance (625 °C/W), low leakage current, dual-diode configuration in ultra-small SOT-363, and RoHS-compliant lead-free plating.
Technical Context
This dual Zener diode integrates two independent 10 V zener elements in a single SOT-363 package, sharing no internal connection-each diode operates as a discrete, polarity-defined junction. It uses planar die construction for stable breakdown characteristics and supports bidirectional voltage clamping when configured back-to-back.
Thermal performance is defined by 625 °C/W junction-to-ambient resistance on FR4 PCB with recommended pad layout, and derating begins linearly above 25 °C ambient per the published power derating curve. The device is specified for operation from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V nominal, 9.4–10.6 V range at 5 mA test current - ensures tight regulation tolerance in feedback loops. |
| Power Dissipation (PD) | 200 mW at 25 °C - limits continuous clamp energy in low-power protection circuits. |
| Zener Impedance (ZZT) | 20 Ω max at 5 mA - maintains stable output voltage under varying load current. |
| Reverse Leakage (IR) | 0.2 µA max at 7 V - minimizes quiescent current in battery-sensitive applications. |
| Thermal Resistance (RθJA) | 625 °C/W - defines temperature rise per mW dissipated on standard FR4 layout. |
| Operating Temperature | –65 °C to +150 °C - supports industrial and automotive under-hood environments. |
Pinout & Package
Package: SOT-363 (SC-70-6), ultra-small surface-mount plastic case, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Unbonded terminal - must be left floating or grounded per layout guidelines; no electrical function. |
| 2 (C1) | Cathode of Diode 1 | Primary cathode for first Zener element; connects to regulated rail or clamp node. |
| 3 (A1) | Anode of Diode 1 | Anode of first Zener; ties to reference or ground depending on bias configuration. |
| 4 (A2) | Anode of Diode 2 | Anode of second independent Zener; enables dual-rail or bidirectional clamping. |
| 5 (C2) | Cathode of Diode 2 | Second cathode; allows separate 10 V regulation path or series/parallel stacking. |
| 6 (NC) | No Connect | Unbonded terminal - no routing or soldering required; avoids parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Zener elements | Two isolated 10 V Zeners in one SOT-363 - reduces board area vs. discrete dual-diode solutions. |
| Planar die construction | Enables repeatable 9.4–10.6 V zener tolerance and low parametric drift over temperature. |
| Lead-free / RoHS compliant | Matte tin finish over Alloy 42 leadframe - meets global environmental compliance without solderability penalty. |
| Low thermal resistance packaging | 625 °C/W RθJA on FR4 - supports reliable operation up to +150 °C junction temperature. |
Applications
| Power Supply Feedback Regulation | Overvoltage Clamp for MCU I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BS-7-F | Single 10 V Zener in SOT-363; no dual-element topology; 150 mW rating. | Lacks independent second Zener - unsuitable for back-to-back clamping or dual-rail designs. | Select only when single-shunt reference suffices and board space permits adding a second device. |
| BZX84C10LT1G | Single 10 V Zener in SOT-23; same 10 V spec but no dual configuration; 350 mW PD. | Requires two placements for dual functionality; higher power rating irrelevant for 200 mW use cases. | Choose if legacy SOT-23 footprint compatibility is mandatory and dual-diode integration is not required. |
Compared with MMBZ5240BS-7-F and BZX84C10LT1G, BZX84C10S-7-F uniquely delivers two matched 10 V Zeners in one SOT-363, enabling compact bidirectional clamping or dual-reference generation without layout compromise or performance trade-offs.

FAQ
What is the maximum zener impedance for BZX84C10S-7-F and at what test condition?
The maximum zener impedance is 20 Ω, measured at a test current of 5 mA and frequency of 1 kHz. This value reflects dynamic resistance near the knee of the breakdown curve and directly impacts regulation stability under varying load conditions in feedback networks.
How are the two Zener diodes arranged internally in the SOT-363 package?
The two Zener diodes are fully independent, with no internal connection between them. Pin 2 (C1) and Pin 3 (A1) form the first diode; Pin 4 (A2) and Pin 5 (C2) form the second. Pins 1 and 6 are unconnected and must remain floating.
Can BZX84C10S-7-F be used for bidirectional ESD protection?
No - it is not rated or characterized for ESD immunity (e.g., IEC 61000-4-2). Its 200 mW power rating and 20 Ω impedance are optimized for steady-state regulation and slow transients, not nanosecond ESD pulses. Use dedicated TVS diodes like D3V3M1U for ESD protection.
What is the meaning of the "-7-F" suffix in the part number?
The "-7-F" suffix indicates tape-and-reel packaging: 3000 units per reel, with lead-free (RoHS-compliant) matte tin plating. It follows Diodes Incorporated's standard ordering convention for SOT-363 devices and does not affect electrical specifications.
