Product details

Overview

1N5384BRLG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 160 V, ±5% tolerance, 8 mA test current (IZT), and maximum zener impedance of 25 Ω at IZT - designed for precision voltage regulation in high-voltage DC power supplies and overvoltage protection circuits.

For engineers reviewing the 1N5384BRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 160 V nominal zener voltage, 350 A peak surge rating at 8.3 ms, 1.1 V forward voltage at 1.0 A, 0.5 mA leakage current at 122 V, and Pb-free Surmetic™ 40 plastic package with cathode band polarity marking.

Technical Context

This device operates as a silicon-oxide passivated junction Zener regulator, delivering stable reverse-biased breakdown performance across −65 °C to +200 °C ambient range. Its thermal design relies on junction-to-lead resistance (θJL = 25 °C/W) and lead-length-dependent derating - critical for sustained 5 W dissipation at TL ≤ 25 °C.

The 1N5384BRLG exhibits a positive temperature coefficient (~0.11 mV/°C per volt, extrapolated from Figure 3 for 160 V units), enabling predictable drift compensation in series-connected reference designs. It supports non-repetitive surge currents up to 1650 A at 8.3 ms pulse width, validated per JEDEC standards.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	152–168 V @ I_ZT = 8 mA - defines regulated output voltage window under standard test conditions
Power Dissipation (P_D)	5 W @ T_L = 25 °C - maximum continuous DC power handling with 3/8″ lead length
Zener Impedance (Z_ZT)	25 Ω max @ I_ZT = 8 mA - ensures low dynamic resistance for tight regulation under load transients
Leakage Current (I_R)	0.5 mA max @ V_R = 122 V - guarantees minimal shunt loss below breakdown threshold
Surge Current (I_RM)	1650 A peak @ 8.3 ms - enables robust transient suppression without failure in surge-prone inputs
Forward Voltage (V_F)	1.2 V max @ I_F = 1.0 A - supports use as bidirectional clamp or rectifier in auxiliary paths
ESD Rating	Class 3 (>16 kV HBM) - provides inherent electrostatic immunity during handling and PCB assembly

Pinout & Package

Package: Axial-lead Surmetic™ 40 plastic case (JEDEC CASE 017AA), void-free transfer-molded thermosetting material, cathode indicated by color band, RoHS-compliant Pb-free construction.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5384BRL	Identical electrical specs; differs only in packaging - RLP (reel) vs RLG (Pb-free reel)	No functional difference; used where Pb-free compliance is not mandated by end-market regulations	Select 1N5384BRLG for RoHS-compliant production; choose 1N5384BRL only if legacy Pb-based assembly is confirmed
SMCJ160A	TVS diode with 160 V standoff, 200 W peak power, unidirectional - not a Zener regulator	Designed for transient suppression only; lacks stable DC regulation capability or low-Z_ZT	Use SMCJ160A only for surge clamping; never as DC voltage reference - 1N5384BRLG provides regulation, SMCJ160A does not

Compared with 1N5384BRLG, the 1N5384BRL offers identical regulation performance but lacks Pb-free certification, while SMCJ160A serves a fundamentally different function - transient absorption without DC regulation - making it unsuitable as a functional replacement in reference or biasing circuits.

FAQ

What is the nominal zener voltage and tolerance of the 1N5384BRLG?

The 1N5384BRLG has a nominal zener voltage of 160 V with a guaranteed tolerance of ±5%, corresponding to a minimum of 152 V and maximum of 168 V at I_ZT = 8 mA. This tolerance is defined per JEDEC standards and applies specifically to the "B" suffix variant, ensuring consistent regulation performance across production lots without binning or adjustment.

Can the 1N5384BRLG be used in surface-mount designs?

No - the 1N5384BRLG uses an axial-lead Surmetic™ 40 plastic package (CASE 017AA) with 0.330–0.350 inch body length and 0.037–0.043 inch lead diameter. It is not compatible with SMT reflow processes or pick-and-place automation. For surface-mount equivalents, consider onsemi's NSZV160F or similar SOD-123 packages - but note these differ in power rating, impedance, and surge capability versus the 5 W 1N5384BRLG.

What is the maximum steady-state power dissipation for the 1N5384BRLG?

The 1N5384BRLG is rated for 5 W maximum steady-state power dissipation at lead temperature (T_L) = 25 °C with 3/8 inch lead length. Above 25 °C, it must be derated at 40 mW/°C - meaning at 75 °C lead temperature, maximum allowable power drops to 3 W. This derating is critical for thermal reliability in enclosed enclosures or high-ambient environments.

Does the 1N5384BRLG meet RoHS requirements?

Yes - the "G" suffix in 1N5384BRLG explicitly denotes a Pb-free package compliant with EU RoHS Directive 2011/65/EU and China RoHS. The device uses lead-free terminations and RoHS-compliant molding compound, verified per onsemi's Soldering and Mounting Techniques Reference Manual (SOLDERRM/D). Full compliance documentation is available upon request.

How is polarity identified on the 1N5384BRLG?

Polarity on the 1N5384BRLG is marked by a single cathode band located near one end of the axial plastic body. The banded end is the cathode; the opposite end is the anode. This marking aligns with JEDEC standard orientation and must be observed during PCB layout to ensure correct reverse-bias connection for zener regulation functionality.
