Product details
Overview
BZB100A,115 from Nexperia is a bidirectional Zener diode in SOD323 (SC-76) package, designed for overvoltage clamping in high-voltage AC/DC signal paths. It delivers 95–105 V working voltage at 1 mA, supports 0.23 A non-repetitive peak reverse current (tp = 100 µs), and sustains 30 W non-repetitive peak reverse power dissipation - deployed specifically to protect EL driver ICs from transient overvoltage.
For engineers reviewing the BZB100A,115 datasheet, BZB100A,115 pinout, BZB100A,115 application, or BZB100A,115 equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive environments, thermal resistance under FR4 mounting, differential resistance ≤700 Ω, and EL lamp circuit compatibility with 220 VPP limits.
Technical Context
The BZB100A,115 integrates two anti-parallel Zener diodes in a single SOD323 package, enabling symmetrical ±100 V clamping without external polarity coordination. Its 123 mV/K temperature coefficient and 10 pF capacitance at 1 MHz support stable regulation in fast-switching EL driver feedback loops.
It operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and thermal resistance as low as 150 K/W on ceramic PCB - critical for sustained surge handling in space-constrained automotive lighting modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ Working Voltage | 95–105 V at IZ = 1 mA: defines precise bidirectional clamping threshold for 220 VPP EL driver protection. |
| IZSM Peak Reverse Current | 0.23 A (tp = 100 µs): enables single-event transient suppression without latch-up or degradation. |
| PZSM Peak Power Dissipation | 30 W (tp = 100 µs): provides robust surge margin for repetitive EL lamp switching transients. |
| rdif Differential Resistance | ≤700 Ω: ensures minimal voltage deviation during clamping, preserving driver IC input integrity. |
| Cd Diode Capacitance | 10 pF at f = 1 MHz, VR = 0 V: avoids signal distortion in high-frequency EL drive waveforms. |
| Tj Max Junction Temperature | 150 °C: supports operation in under-hood automotive environments with no derating below 125 °C ambient. |
Pinout & Package
SOD323 (SC-76) plastic surface-mounted package: 2-pin, ultra-compact footprint (2.3 × 1.35 mm), optimized for high-density PCB layouts and reflow/wave soldering per Nexperia's validated footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Anode of first Zener; forms one half of bidirectional clamp path - connects to positive rail or signal line. |
| 2 | Cathode (Diode 2) | Anode of second Zener; completes symmetrical clamp - ties to complementary rail or return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTGB, HTRB, and ESD testing - suitable for front-end protection in vehicle lighting ECUs. |
| Bidirectional configuration | Single-device ±VZ clamping eliminates need for dual discrete Zeners and matching tolerances - reduces BOM count and layout area by 50%. |
| Low thermal resistance | Rth(j-a) = 150 K/W on Al2O3 PCB: enables >2× higher sustained power handling vs. standard FR4 mounting. |
| Stable temperature coefficient | +123 mV/K typical: ensures predictable VZ drift across operating range - critical for repeatable EL brightness control. |
Applications
| Automotive EL Lamp Protection | Industrial AC Signal Clamping |
|---|---|
|
Use Scenario: Protecting EL driver ICs in automotive interior lighting (e.g., dashboard backlighting) against load-dump-induced transients up to 220 VPP. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between driver output and EL foil - conducts only during overvoltage events, otherwise presents <10 pF loading. Use Value: Prevents permanent damage to sensitive driver ICs while maintaining waveform fidelity for consistent luminance control. |
Use Scenario: Clamping AC-coupled sensor signals in industrial PLC analog input modules exposed to ESD or inductive kickback. IC Role / Device Role / Timing Role: Front-end transient suppressor on differential signal lines - symmetric conduction limits excursion to ±105 V regardless of polarity. Use Value: Eliminates need for separate positive/negative TVS devices, reducing component count and board space in 24 V system I/O stages. |
| Consumer Display Backlighting | Medical Instrumentation Signal Conditioning |
|
Use Scenario: Overvoltage protection for EL panels in portable medical displays (e.g., ultrasound handhelds) where compact size and low capacitance are mandatory. IC Role / Device Role / Timing Role: Clamp element integrated directly at EL foil terminals - responds within nanoseconds to fast-rising transients from boost converter switching noise. Use Value: Maintains display uniformity by preventing localized foil breakdown, enabled by tight 95–105 V VZ tolerance and sub-100 ns response. |
Use Scenario: Safeguarding precision op-amp inputs in battery-powered diagnostic equipment subjected to accidental probe contact with high-voltage test points. IC Role / Device Role / Timing Role: Input-stage limiter before instrumentation amplifier - clamps excursions beyond ±105 V while adding negligible offset error (<1 µA leakage at 76 V). Use Value: Preserves measurement accuracy and prevents amplifier saturation, supported by IR ≤0.05 µA at VR = 76 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics TZM100-13-F | VZ = 100 V ±5%, PZSM = 25 W (tp = 100 µs), not AEC-Q101 qualified | Lacks automotive qualification; higher leakage (IR ≤0.1 µA at 76 V) | Select when cost sensitivity outweighs automotive compliance and lower leakage is acceptable. |
| Vishay SMBJ100CA | TVS diode, VBR = 100 V min, PPP = 600 W (tp = 1 ms), larger SMB package (4.5 × 3.9 mm) | Higher surge capacity but slower response; unsuitable for high-frequency EL drive waveforms due to >100 pF CJ | Choose only for infrequent, high-energy surges where speed and capacitance are secondary to energy rating. |
Compared with TZM100-13-F and SMBJ100CA, the BZB100A,115 uniquely balances automotive qualification, ultra-low capacitance, and tight VZ tolerance - making it the sole option for space-constrained, high-frequency EL driver protection requiring guaranteed reliability.

FAQ
What is the maximum allowable continuous reverse voltage for BZB100A,115?
The BZB100A,115 has no specified DC reverse voltage rating - it is designed exclusively for transient clamping. Continuous reverse bias must remain below 76 V to ensure IR ≤0.05 µA; operation above this level risks accelerated degradation and increased leakage.
Can BZB100A,115 replace a pair of unidirectional Zeners in series opposition?
Yes - its internal anti-parallel structure replicates two matched 100 V Zeners with identical VZ, rdif, and thermal coupling. This eliminates matching errors and thermal imbalance issues inherent in discrete pairs, improving clamping symmetry and reliability.
Is the SOD323 package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia provides validated reflow soldering footprints and thermal profiles for SOD323. Peak temperatures up to 260 °C are supported, with ramp rates and soak times aligned to IPC-J-STD-020, ensuring reliable joint formation without die stress.
How does thermal resistance vary between FR4 and ceramic PCB mounting?
Rth(j-a) is 415 K/W on standard FR4, 230 K/W with enlarged cathode pad (1 cm²), and 150 K/W on Al2O3 ceramic. This 2.8× improvement enables 2.8× higher average power dissipation in thermally demanding automotive modules.
