Product details

Overview

BZX84-C13,215 from Nexperia is a silicon planar Zener diode in SOT23 package, designed for low-power voltage regulation and reference applications. It provides a nominal 13 V breakdown voltage at 5 mA with ±5 % tolerance, 170 Ω maximum differential resistance, and 30 μA reverse current at 10.4 V. It operates within −55 °C to +150 °C ambient range and supports general-purpose DC rail stabilization in consumer and industrial power supplies.

For engineers reviewing the BZX84-C13,215 datasheet, BZX84-C13,215 pinout, BZX84-C13,215 application, or BZX84-C13,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W junction-to-solder-point), non-repetitive surge capability (80 A peak reverse current), and SOT23 footprint compatibility with automated PCB assembly.

Technical Context

This Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output by conducting reverse current when applied voltage exceeds its specified V_Z. Its operation relies on controlled avalanche breakdown in the p-n junction under reverse bias, with temperature coefficient of +7.0 mV/K at I_Z = 5 mA.

The device exhibits 170 Ω typical dynamic impedance at 5 mA test current, enabling predictable regulation error under load variation. Its 250 mW total power dissipation rating assumes FR4 PCB mounting with single-sided 70 µm copper, and it withstands non-repetitive 40 W reverse surges (100 µs pulse) up to 80 A peak current.

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 regulation band for precision reference use
Differential Resistance (r_dif)	≤170 Ω at I_Z = 5 mA - determines output voltage deviation under current change
Reverse Current (I_R)	≤30 μA at V_R = 10.4 V - ensures low leakage in standby or high-impedance bias networks
Power Dissipation (P_tot)	250 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB
Non-repetitive Peak 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 extended industrial environments
Thermal Resistance (R_th(j-sp))	330 K/W - quantifies heat transfer efficiency from junction to cathode solder point

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MMBZ5243BLT1G	13 V nominal, ±5 %, 150 mW P_tot, 100 Ω r_dif	Lower power rating limits continuous current to ~11.5 mA vs. 19.2 mA for BZX84-C13,215	Select when tighter dynamic impedance is prioritized over power headroom
Vishay NZX13C,113	13 V nominal, ±5 %, 500 mW P_tot, TO-92 package	Through-hole mounting and double power rating require PCB redesign and larger footprint	Select when higher continuous power dissipation is required and SMT is not mandatory

Compared with MMBZ5243BLT1G, BZX84-C13,215 offers 67 % higher power margin and better thermal coupling via SOT23; compared with NZX13C,113, it reduces board area by >70 % but requires careful thermal layout due to lower absolute P_tot.

FAQ

What is the maximum continuous forward current for BZX84-C13,215?

The BZX84-C13,215 is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA under pulsed conditions (tp ≤ 100 μs). In normal Zener operation, it conducts only in reverse bias, and forward voltage remains ≤0.9 V at 10 mA-intended solely for polarity verification or ESD path definition.

Can BZX84-C13,215 be used in parallel for higher power handling?

No-Zener diodes exhibit negative temperature coefficients and parameter spread; paralleling BZX84-C13,215 units causes current hogging and thermal runaway. For higher power, use a single higher-rated Zener (e.g., BZX85 series in DO-35) or active regulation with a pass transistor.

How does the "215" suffix in BZX84-C13,215 relate to marking or packaging?

The "215" is Nexperia's internal package variant code indicating tape-and-reel packaging per EIA-481 standard, with 3,000 units per reel and 8 mm carrier tape width-distinct from the "Y3%" top-side marking which identifies the C-tolerance 13 V variant per Table 4.

Is BZX84-C13,215 qualified for automotive applications?

No-this part is non-automotive qualified per Rev. 7 datasheet Section 13. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select Nexperia's BZX84-C13,215-Q variant (if available) or equivalent AEC-Q101 Zeners such as Diodes Inc. BZX84C13-7-F.
