Product details
Overview
P4SMAJ58ADF-13 from Diodes Incorporated is a 400W surface-mount transient voltage suppressor (TVS) diode in D-FLAT package, designed for unidirectional overvoltage protection of DC power lines and signal interfaces. It features a 58V reverse standoff voltage (VRWM), 64.4–71.2V breakdown range at 1mA, 93.6V clamping voltage at 4.3A peak pulse current, and meets IEC 61000-4-2 ESD immunity (±30kV air/contact). Used in industrial power input stages to protect downstream regulators and microcontrollers.
For engineers reviewing the P4SMAJ58ADF-13 datasheet, P4SMAJ58ADF-13 pinout, P4SMAJ58ADF-13 application, or P4SMAJ58ADF-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under 10/1000µs surge, thermal resistance on FR-4 PCB, and compatibility with automated SMT assembly due to its low-profile D-FLAT footprint.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below VRWM (58V) and rapidly transitions to low-impedance conduction above VBR (64.4–71.2V), limiting transient energy to safe levels. Its glass-passivated junction ensures stable leakage (<1µA at VRWM) and repeatable breakdown behavior across temperature.
The device delivers 400W peak pulse power per 10×1000µs waveform, with thermal resistance RθJA of 114°C/W on standard 1"×1" FR-4 board and 88°C/W on optimized 0.4"×0.5" layout-critical for sustained surge handling in compact industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - sustains single 10×1000µs transients without failure |
| Reverse Standoff Voltage | 58 V - maximum continuous DC operating voltage before clamping begins |
| Breakdown Voltage Range | 64.4–71.2 V @ 1mA - defines reliable turn-on threshold for overvoltage events |
| Clamping Voltage | 93.6 V @ 4.3A - limits voltage seen by protected circuit during worst-case surge |
| ESD Rating | ±30kV (air/contact) per IEC 61000-4-2 - protects against human-body-model discharge events |
| Thermal Resistance (J-A) | 114 °C/W - determines steady-state junction temperature rise on standard PCB layout |
| Package | D-FLAT - 2.25–2.95mm width, 3.95–4.60mm length, 0.90–1.10mm height; optimized for space-constrained SMT |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Same 58V VRWM, but SMB package (higher RθJA ≈ 140°C/W); 600W peak power rating | Larger footprint (4.5×3.9mm vs. D-FLAT's 4.6×2.6mm); less suitable for ultra-dense layouts | Select when higher surge margin is required and board space allows larger package |
| 1.5SMC58A | Same 58V VRWM, DO-214AB package; 1500W peak power; higher clamping voltage (96.8V) | Through-hole compatible; not SMT-optimized; requires manual or wave soldering | Select only for legacy through-hole designs or where 1500W surge headroom justifies added assembly cost |
Compared with SMBJ58A and 1.5SMC58A, P4SMAJ58ADF-13 offers the smallest PCB footprint and lowest thermal resistance among 58V TVS diodes in its power class-making it optimal for space- and thermally constrained industrial SMT designs requiring 400W surge handling.

FAQ
What is the maximum operating temperature for P4SMAJ58ADF-13?
The device supports an operating junction temperature range of –55°C to +150°C. Its thermal resistance (RθJA = 114°C/W on standard FR-4) means that at 1W steady-state dissipation, junction temperature rises ~114°C above ambient-so derating is required above +35°C ambient for continuous operation near PM(AV) = 1.0W.
Does P4SMAJ58ADF-13 meet automotive AEC-Q200 requirements?
No-P4SMAJ58ADF-13 is not AEC-Q200 qualified. It is rated for industrial-grade operation (–55°C to +150°C) and carries RoHS 3 and halogen-free compliance, but lacks the stress testing, qualification reporting, and part-specific PPAP documentation required for automotive under-hood or safety-critical applications.
How does the D-FLAT package affect PCB layout and thermal performance?
The D-FLAT package uses a flat, low-profile leadframe with exposed metal terminals-enabling direct copper pad contact for improved heat transfer. Recommended pad layout (per Diodes Inc. package outline) uses 0.2"×0.25" copper pads on 2oz FR-4 to achieve RθJA = 88°C/W, reducing thermal impedance by ~23% versus standard 1"×1" layout.
Can P4SMAJ58ADF-13 be used for bidirectional transient suppression?
No-it is a unidirectional TVS diode, configured for DC line protection with cathode connected to the protected line and anode to ground. For AC or bidirectional signal lines (e.g., USB, RS-232), a bidirectional variant such as P4SMAJ58CA must be selected, which has symmetrical clamping in both polarities.
