Product details
Overview
SMBJ58CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR at 1 mA), 93.6 V maximum clamping voltage (VC) at 6.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ58CAHE3/52 datasheet, SMBJ58CAHE3/52 pinout, SMBJ58CAHE3/52 application, or SMBJ58CAHE3/52 equivalent, this device is evaluated for bidirectional surge protection where low clamping ratio, AEC-Q101 qualification, and MSL Level 1 moisture sensitivity are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical electrical characteristics forward and reverse. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, while the low incremental surge resistance supports consistent clamping performance across multiple transient events.
The device complies with ANSI/IEEE C62.35 standards for surge suppressors and meets UL 497B recognition (QVGQ2) for protector classification. With a thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), it sustains operation up to 150 °C junction temperature under defined PCB pad layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold |
| VBR min/max | 64.4 V / 71.2 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during overvoltage events |
| VC @ IPPM | 93.6 V at 6.4 A - Clamping voltage under 10/1000 µs surge; determines maximum stress imposed on protected circuitry |
| PPPM | 600 W - Peak pulse power handling capability; enables robust protection against lightning-induced or inductive-switching transients |
| IPPM | 6.4 A - Peak pulse current corresponding to VC; sets minimum surge current level the device can safely clamp |
| TJ max | +150 °C - Maximum junction temperature; supports operation in high-ambient environments like industrial motor drives |
| MSL Level | Level 1 per J-STD-020 - No floor life limitation; allows unlimited exposure to ambient conditions prior to reflow |
Pinout & Package

Applications
| Industrial Motor Drives | Telecom Line Cards |
|---|---|
Use Scenario: Protection of gate drivers and bus voltage sensing circuits against inductive kickback from IGBT/MOSFET switching.

Use Scenario: Surge suppression on Ethernet PHY power rails and RS-485 data lines exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary TVS element shunting transient energy before it reaches communication ICs. Use Value: Maintains signal integrity by limiting common-mode transients to <95 V while supporting >100,000 surge cycles. |
| Automotive Body Control Modules | Consumer Power Adapters |
Use Scenario: Input-stage protection for 12 V/24 V supply inputs subjected to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: First-line defense against slow-rising (100 ms) and fast-rising (5 ns) transients on vehicle power nets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA-M3/52 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification | No difference in protection performance or board-level integration | Select when halogen-free material compliance is required by OEM environmental policy |
| SMAJ58CAHE3/A | Lower 400 W PPPM, SMA package (smaller footprint, higher RθJA = 140 °C/W) | Reduced surge margin; less suitable for high-reliability industrial or automotive use | Consider only for space-constrained consumer applications with lower surge threat levels |
Compared with SMBJ58CAHE3/52, the M3/52 alternative offers identical protection capability with halogen-free construction, while the SMAJ58CAHE3/A trades 33 % peak power derating and higher thermal resistance for smaller board area - making the SMBJ58CAHE3/52 optimal for demanding surge environments requiring full 600 W headroom and automotive qualification.

FAQ
What is the clamping voltage of SMBJ58CAHE3/52 under a 10/1000 µs surge?
The SMBJ58CAHE3/52 clamps to a maximum of 93.6 V at its rated peak pulse current of 6.4 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 60 V-rated downstream components.
Is SMBJ58CAHE3/52 suitable for automotive applications?
Yes, SMBJ58CAHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation - making it appropriate for body control modules, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal and vibration stress is mandatory.
How does the bidirectional configuration of SMBJ58CAHE3/52 affect circuit design?
The bidirectional configuration of SMBJ58CAHE3/52 eliminates polarity concerns during placement - either terminal may connect to any side of a differential line or ungrounded rail. This simplifies layout for AC-coupled signals, floating power domains, or dual-rail protection schemes, and ensures symmetrical clamping behavior regardless of transient polarity, unlike unidirectional variants that require cathode orientation.
What is the maximum steady-state power dissipation of SMBJ58CAHE3/52?
The SMBJ58CAHE3/52 has a maximum steady-state power dissipation (PD) of 5.0 W at 50 °C ambient with infinite heatsink conditions. In typical PCB-mounted configurations using 0.2" × 0.2" copper pads per terminal, derating applies above 25 °C ambient - actual usable DC power must be calculated using RθJA = 100 °C/W and TJ ≤ 150 °C limits to avoid thermal runaway.
Does SMBJ58CAHE3/52 require special handling during PCB assembly?
No - SMBJ58CAHE3/52 is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering processes. No baking, dry pack, or floor-life tracking is required, and its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards - enabling direct placement into high-volume SMT lines.
