Product details

Overview

BZX84-C13,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 13 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-power voltage reference and overvoltage protection in DC power rails.

For engineers reviewing the BZX84-C13,235 datasheet, BZX84-C13,235 pinout, BZX84-C13,235 application, or BZX84-C13,235 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (≤170 Ω), reverse current at 10.4 V (≤30 μA), thermal resistance (330 K/W to solder point), and non-repetitive surge capability (80 A peak pulse).

Technical Context

This device operates as a two-terminal shunt voltage regulator, maintaining stable output by conducting reverse current above its specified Zener voltage (12.4 V to 14.1 V at I_Z = 5 mA). Its silicon planar construction ensures predictable breakdown behavior with low temperature coefficient (±0.1 mV/K typical at 13 V) and minimal capacitance (≤80 pF at 0 V).

The SOT23 package enables high-density PCB placement while supporting thermal dissipation via cathode tab soldering (R_th(j-sp) = 330 K/W). It complies with IEC 60134 absolute maximum ratings, including 40 W non-repetitive peak reverse power (100 μs pulse) and 200 mA forward current limit.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	12.4 V to 14.1 V at I_Z = 5 mA - defines regulated output range under nominal bias
Differential Resistance (r_dif)	≤170 Ω - determines regulation stiffness and load-induced voltage deviation
Reverse Current (I_R)	≤30 μA at V_R = 10.4 V - sets leakage-related quiescent power loss in standby
Total Power Dissipation (P_tot)	250 mW at T_amb ≤ 25 °C on FR4 PCB - limits continuous regulation current to ~19 mA at 13 V
Non-repetitive Peak Reverse Current (I_ZSM)	2.5 A at t_p = 100 μs - supports transient overvoltage clamping without failure
Junction Temperature (T_j)	−55 °C to +150 °C - enables operation in industrial ambient environments
Thermal Resistance (R_th(j-sp))	330 K/W - quantifies temperature rise per watt at cathode solder joint

Pinout & Package

Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint (2.8 mm × 1.4 mm × 1.1 mm), cathode tab optimized for thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode (A)	Forward-biased terminal; connects to lower-potential node in regulation path
2	Not Connected (n.c.)	Internally unconnected; must remain floating or grounded per layout best practice
3	Cathode (K)	Zener breakdown terminal; ties to regulated voltage node and provides primary thermal path

Key Features

Feature	Design Value
±5 % Zener voltage tolerance	Enables cost-effective voltage referencing where tight regulation is not critical
250 mW power rating	Supports regulation in low-current analog circuits and microcontroller supply monitoring
Low 80 pF diode capacitance	Minimizes signal coupling in high-frequency bypass and noise-sensitive references
150 °C max junction temperature	Permits reliable operation in enclosed industrial enclosures without forced cooling
SOT23 footprint compatibility	Allows drop-in replacement in existing designs using JEDEC-standard 3-pin SMD layout

Applications

Power Supply Reference

Use Scenario: Providing stable 13 V reference for ADC voltage dividers or op-amp bias networks in battery-powered sensors.

IC Role / Device Role / Timing Role: Shunt voltage reference establishing precise DC offset independent of load current variation.

Use Value: Maintains <±1 % reference drift across −40 °C to +85 °C ambient due to low temperature coefficient (±0.1 mV/K).

Use Scenario: Clamping 12 V rail against ESD or load-dump transients in automotive body electronics modules.

IC Role / Device Role / Timing Role: Passive overvoltage clamp absorbing surge energy before downstream ICs.

Use Value: Withstands 2.5 A non-repetitive peak current (100 μs) without degradation, limiting rail excursion to ≤14.1 V.

Signal Level Translation

Use Scenario: Generating fixed 13 V bias for JFET gate control in audio preamplifier front-ends.

IC Role / Device Role / Timing Role: Voltage-defined current sink enabling predictable transconductance setting.

Use Value: Differential resistance ≤170 Ω ensures <0.2 V shift under 1 mA bias current variation.

Use Scenario: Setting constant current for LED indicator circuits in industrial HMIs with 12–15 V input rails.

IC Role / Device Role / Timing Role: Two-terminal current regulator defining LED drive independent of supply ripple.

Use Value: 250 mW rating allows up to 19 mA continuous current at 13 V, sufficient for 5–10 mA LED bias.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MMBZ5243B	13 V nominal, ±5 %, 350 mW P_tot, 200 °C T_j max	Higher power handling but larger thermal footprint (SOT23 vs SOT23)	Select when >250 mW continuous dissipation is required and board space permits same package
Vishay BZX84-C13-TP	13 V nominal, ±5 %, identical 250 mW rating and SOT23 package	Same electrical specs; differs only in tape-and-reel packaging and RoHS compliance documentation	Drop-in substitute where Vishay sourcing or specific compliance reporting is mandated

Compared with MMBZ5243B, BZX84-C13,235 offers tighter thermal integration (330 K/W to solder point vs ~400 K/W) for compact layouts; versus BZX84-C13-TP, it shares identical regulation performance but differs in traceability and lot-level test reporting.

FAQ

What is the guaranteed Zener voltage range for BZX84-C13,235 at 5 mA test current?

The guaranteed Zener voltage range is 12.4 V to 14.1 V at I_Z = 5 mA and T_j = 25 °C, reflecting its ±5 % tolerance grade. This range remains valid across the full operating junction temperature span (−55 °C to +150 °C), with temperature coefficient of ±0.1 mV/K ensuring minimal drift in real-world conditions.

Can BZX84-C13,235 be used in parallel for higher power dissipation?

No - BZX84-C13,235 is not designed for parallel operation due to manufacturing variations in Zener voltage and dynamic resistance. Parallel connection risks current hogging, thermal runaway, and premature failure. For higher power needs, select a single higher-rated Zener (e.g., 500 mW through-hole or SOD-123 variant) or use active regulation.

How does the "235" suffix in BZX84-C13,235 relate to marking or packaging?

The "235" suffix denotes the specific ordering code per Nexperia's packaging matrix: it identifies the 3,000-piece 8 mm tape-and-reel configuration (EIA-481 compliant) with standard moisture sensitivity level (MSL 1) and RoHS-compliant finish. The device marking on the SOT23 body is "Y3%", per Table 4 of the datasheet.

Is BZX84-C13,235 qualified for automotive applications?

No - BZX84-C13,235 is a commercial-grade part and not AEC-Q101 qualified. Nexperia explicitly states in Revision 7 that the BZX84_SER series is non-automotive qualified. For automotive use, engineers must select designated -Q variants (e.g., BZX84-C13,215-Q) which undergo extended temperature cycling, humidity testing, and failure analysis per AEC standards.
