Product details
Overview
P6SMAJ58ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power lines and signal interfaces. It features a reverse standoff voltage of 58.0 V, breakdown voltage range of 64.4–74.6 V at 1.0 mA test current, clamping voltage of 93.6 V at 6.4 A peak pulse current, and fast response time under 1.0 ns. It is used in industrial power supplies to protect downstream regulators from lightning-induced surges.
For engineers reviewing the P6SMAJ58ADF-13 datasheet, P6SMAJ58ADF-13 pinout, P6SMAJ58ADF-13 application, or P6SMAJ58ADF-13 equivalent, this page provides verified electrical parameters, D-FLAT package layout details, clamping performance under 10/1000 µs transients, thermal resistance values for PCB mounting variants, and direct alternatives with documented voltage and power differences.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages above its reverse standoff voltage (VRWM = 58.0 V), limiting voltage across protected circuitry to ≤93.6 V during 6.4 A peak pulses. Its glass-passivated die ensures stable leakage (<1.0 µA at VRWM) and repeatable breakdown characteristics.
The device uses a unidirectional configuration with cathode-band polarity marking, requiring correct orientation on PCBs. Thermal resistance varies with copper pad size: RθJA = 92 °C/W on 0.4" × 0.5" 2 oz copper, enabling reliable 1.5 W steady-state dissipation at TL = +75°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A (Bourns) | Same 58 V VRWM, but SMB package (larger footprint, RθJA = 110 °C/W) | Requires more PCB area; lower thermal efficiency on compact boards | Select when legacy SMB layout exists and thermal derating margin >20% |
| 1.5SMC58A (ON Semiconductor) | Identical VRWM and clamping, but SMC package (6.2 mm × 4.6 mm) and higher IPP = 7.0 A | Better surge handling but incompatible with D-FLAT land pattern | Choose for higher reliability in high-repetition surge environments where board space allows |
Compared with SMBJ58A and 1.5SMC58A, P6SMAJ58ADF-13 delivers equivalent protection in 30% less board area and superior thermal performance on small copper pads-critical for space-constrained industrial and automotive modules.

FAQ
What is the maximum operating temperature for P6SMAJ58ADF-13?
The device supports continuous operation from –55 °C to +150 °C junction temperature. At ambient temperatures above +75 °C, derating applies: power dissipation must be reduced linearly to zero at +150 °C, per the pulse derating curve in Figure 1 of DS38930 Rev. 2–2.
Can P6SMAJ58ADF-13 be used in bidirectional configurations?
No-it is a unidirectional TVS diode with anode/cathode terminals and a cathode band marking. For bidirectional protection, two devices must be connected in series opposing, or a dedicated bidirectional part like P6SMBJ58CA should be selected.
How does the D-FLAT package affect PCB layout compared to SMA?
D-FLAT measures 4.65 mm × 2.80 mm, ~35% smaller than standard SMA (4.5 mm × 2.7 mm × 2.2 mm height). Its low profile (max 1.10 mm) reduces mechanical stress on solder joints and enables placement under connectors or shields-verified via Diodes' suggested pad layout PN D-FLAT-01.
Is P6SMAJ58ADF-13 compliant with AEC-Q200 for automotive use?
No-this part is not AEC-Q200 qualified. While widely used in automotive BCMs, it lacks the extended temperature cycling, vibration, and failure analysis testing required for automotive qualification. For AEC-Q200 applications, consider Diodes' AEC-Q200–qualified AP6SMAJ58A variant.
