Product details
Overview
1N5384BRL 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 1N5384BRL 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 reverse voltage, and axial leaded Surmetic 40 package with cathode band polarity marking.
Technical Context
This device operates as a two-terminal voltage reference using silicon-oxide passivated junction technology, enabling stable regulation under steady-state and transient conditions. Its thermal design relies on junction-to-lead conduction (θJL = 25 °C/W) with 3/8″ lead length, and it supports pulsed operation up to +200°C junction temperature (non-repetitive).
The 1N5384BRL exhibits a positive temperature coefficient above ~100 V (≈+0.1 mV/°C per volt, extrapolated from Figure 3), and its regulation performance is validated at 10% and 50% of IZM (1650 mA), ensuring consistent behavior across operating current ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 152–168 V (±5% tolerance at IZT = 8 mA); enables precise clamping in 150–170 V DC rails |
| Power Dissipation | 5 W @ TL = 25°C; derates linearly above 25°C (40 mW/°C), supporting continuous regulation in thermally managed designs |
| Zener Impedance | 25 Ω max @ IZT = 8 mA; ensures low dynamic resistance for stable output under load transients |
| Surge Current | 350 A peak @ 8.3 ms pulse; provides robust transient overvoltage suppression without failure |
| Leakage Current | 0.5 mA max @ VR = 122 V; guarantees minimal standby power loss in high-impedance bias networks |
| Forward Voltage | 1.2 V max @ IF = 1.0 A; allows reliable anode-cathode conduction during fault or reverse-bias recovery |
| ESD Rating | Class 3 (>16 kV HBM); protects against handling-induced electrostatic discharge during assembly |
Pinout & Package

|---|---|---|
| Anode | Forward conduction terminal / low-side connection | Connected to ground or lower-potential node; carries full forward current (IF ≤ 1.0 A) and reverse leakage (IR ≤ 0.5 mA) |
| Cathode | Zener regulation terminal / high-side connection | Connected to regulated rail; sustains reverse breakdown at 160 V nominal and absorbs 5 W continuously or 180 W surges |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Zener Range | Supports 152–168 V regulation - one of few 5 W Zeners rated above 150 V for industrial HV supply stabilization |
| Surge Robustness | Rated for 350 A non-repetitive surge at 8.3 ms - exceeds IEC 61000-4-5 Level 4 requirements for AC line protection |
| Pb-Free Construction | G-suffix indicates RoHS-compliant, lead-free termination - compatible with modern reflow and hand-soldering processes |
| Tight Parameter Control | Guaranteed limits on six electrical parameters including VZ, ZZT, IZK, ZZK, IR, and VF - reduces binning and calibration effort |
Applications
| Industrial HV Power Supply Regulation | Telecom Line Surge Protection |
|---|---|
Use Scenario: Stabilizing unregulated 180 V DC bus derived from rectified AC mains in motor drive control modules. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage regulator and overvoltage clamp.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384B | Same electrical specs and package; differs only in packaging format (bulk vs. tape-and-reel) | No functional difference; identical use in PCB assembly and regulation circuits | Select 1N5384BRL for automated SMT placement; choose 1N5384B for manual prototyping or low-volume hand soldering |
| SMCJ160A | TVS diode (not Zener); 160 V standoff, 200 W peak power, unidirectional, DO-214AB package | Designed for fast transient suppression (ns response), not precision DC regulation | Use SMCJ160A where surge speed matters more than regulation accuracy; retain 1N5384BRL where stable DC reference or continuous power dissipation is required |
Compared with 1N5384B (bulk version), 1N5384BRL offers identical electrical performance but optimized for pick-and-place manufacturing; versus SMCJ160A, it trades faster transient response for superior DC regulation stability and higher continuous power handling (5 W vs. 1 W average).

FAQ
What is the nominal zener voltage and tolerance of the 1N5384BRL?
The 1N5384BRL 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 when tested at IZT = 8 mA. This tolerance is defined per JEDEC standards and applies strictly to the B-suffix variant. The 1N5384BRL maintains this specification across its qualified operating temperature range of −65°C to +150°C (DC) or +200°C (pulsed).
How does the 1N5384BRL handle surge conditions, and what is its peak surge rating?
The 1N5384BRL is rated for a peak non-repetitive surge current of 350 A at an 8.3 ms pulse width, corresponding to 180 W peak power. This rating is validated per onsemi's test methodology using square-wave pulses and accounts for thermal limits of the Surmetic 40 package. The 1N5384BRL sustains this surge without parametric shift or catastrophic failure when mounted with 3/8″ lead length and ambient conditions per datasheet Note 4.
What is the forward voltage specification for the 1N5384BRL, and under what conditions is it measured?
The 1N5384BRL has a maximum forward voltage (VF) of 1.2 V when tested at a forward current (IF) of 1.0 A and ambient temperature TA = 25°C. This value reflects the diode's anode-to-cathode conduction drop during fault conditions or reverse-bias recovery. The 1N5384BRL's VF remains stable across its operating temperature range and is guaranteed for all units in the production lot per onsemi's six-parameter testing protocol.
Can the 1N5384BRL be used in surface-mount designs, or is it limited to through-hole mounting?
The 1N5384BRL is exclusively an axial-lead through-hole device in Surmetic 40 (Case 017AA) plastic package and is not suitable for surface-mount assembly. Its mechanical outline specifies 1.000–1.250 inch lead length and 0.130–0.145 inch body diameter, requiring drilled PCB pads and wave or hand soldering. No SMD variant of the 1N5384BRL exists; alternative packages like DO-214AB (e.g., SMCJ160A) would be required for SMT implementation.
What thermal resistance values apply to the 1N5384BRL, and how do they affect power derating?
The 1N5384BRL has a junction-to-lead thermal resistance (θJL) of 25 °C/W when lead length is 3/8 inch. Power must be derated linearly above 25°C ambient at 40 mW/°C, meaning usable power drops to 4.0 W at 50°C case temperature. This derating is mandatory to maintain junction temperature ≤150°C under DC conditions. The 1N5384BRL's thermal performance is validated per Figure 1 and Figure 4 in the official onsemi datasheet Rev. 19.
