Product details
Overview
SMBG60CAHE3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMBG (DO-215AA) surface-mount package, designed for clamping voltage transients on signal or power lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), <1 µA reverse leakage at VWM, and clamps to ≤96.8 V at 6.2 A peak pulse current - used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SMBG60CAHE3/52 datasheet, SMBG60CAHE3/52 pinout, SMBG60CAHE3/52 application, or SMBG60CAHE3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), and direct replacement guidance for robust overvoltage design in harsh environments.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown and low leakage, while the SMBG package supports automated placement and meets MSL level 1 (260 °C reflow).
Designed for transient suppression per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it delivers fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and handles repetitive surges at 0.01% duty cycle - validated for automotive-grade reliability under -55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 60 V - maximum continuous reverse voltage before clamping begins; defines operating margin for 48 V automotive systems. |
| Breakdown Voltage (VBR) | 66.7–73.7 V at 1 mA - precise threshold where device transitions from high-impedance to low-impedance clamping state. |
| Clamping Voltage (VC) | ≤96.8 V at 6.2 A (10/1000 µs) - limits downstream voltage stress during surge events to protect sensitive ICs. |
| Peak Pulse Power (PPPM) | 600 W - energy-handling capability for standardized lightning/surge waveforms without failure. |
| Reverse Leakage (ID) | <1 µA at 60 V - negligible standby current that avoids signal distortion or power loss in high-impedance circuits. |
| Junction Temperature Range | -55 °C to +150 °C - enables deployment in engine bay, powertrain, and industrial control environments. |
| AEC-Q101 Qualified | Yes - certified for automotive electronic components per stress test requirements including HTOL, TCT, and ESD. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, bidirectional configuration with no polarity marking - symmetrical terminals suitable for AC-coupled or differential signal lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge path | Either terminal serves as anode or cathode depending on transient polarity; no band marking required. |
| Case (cathode band absent) | Thermal and mechanical anchor | Exposed metal slug provides low-inductance path and aids heat dissipation into PCB copper pads. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics with extended temperature cycling, high-temperature operating life, and ESD robustness. |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 3 surges (1 kV open-circuit, 0.5 Ω source impedance) without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in MOSFETs/ICs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard 260 °C lead-free reflow without popcorn cracking or delamination. |
| Glass-passivated junction | Ensures stable VBR tolerance, low leakage drift over time, and immunity to humidity-induced parameter shift. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |

IC Role / Device Role / Timing Role: Secondary-side TVS across 5–20 V output rails to absorb residual surges escaping primary-side MOVs and Y-capacitors. Use Value: Enables compact form factor via SMBG footprint while delivering 600 W pulse handling - critical for space-constrained adapter designs. |
Use Scenario: Protecting Ethernet PHY interfaces and DSL line drivers from induced surges on outdoor telecom cables subject to lightning coupling. IC Role / Device Role / Timing Role: Bidirectional TVS placed between transformer center-tap and PHY ground to clamp common-mode surges without disrupting DC bias. Use Value: Supports compliance with GR-1089-CORE (telecom surge immunity) thanks to repeatable 600 W clamping performance and AEC-Q101 process consistency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM (60 V), lower PPPM (600 W unchanged), but higher VC (103 V @ 6.2 A); non-AEC-Q101 rated. | Limited to commercial/industrial use; not qualified for automotive under hood or powertrain locations. | Select SMBJ60CA only if AEC-Q101 is not required and layout allows slightly higher clamping voltage margin. |
| SMAJ60CA | Same VWM and VBR, but lower PPPM (400 W); SMA package (DO-214AC) has higher RθJA (140 °C/W) vs. SMBG (100 °C/W). | Reduced surge energy handling and poorer thermal performance limit use to low-duty-cycle or low-power signal lines. | Choose SMAJ60CA only when board space constraints prohibit SMBG footprint and surge threat level is below IEC 61000-4-5 Level 2. |
Compared with SMBJ60CA and SMAJ60CA, SMBG60CAHE3/52 offers superior thermal management (RθJA = 100 °C/W), automotive qualification, and tighter clamping - making it the preferred choice for mission-critical 12 V/24 V system protection where reliability and repeatable performance are mandatory.

FAQ
What is the key difference between SMBG60CAHE3/52 and unidirectional SMBG60AHE3/52?
The SMBG60CAHE3/52 is bidirectional, meaning it clamps voltage transients equally in both polarities with symmetrical VBR and VC characteristics - ideal for AC-coupled or differential lines. In contrast, SMBG60AHE3/52 is unidirectional and features a cathode band; it conducts only in reverse bias and requires correct polarity orientation. Both share the same SMBG package, 60 V VWM, and 600 W PPPM, but SMBG60CAHE3/52 eliminates polarity concerns in floating or bidirectional signal paths.
Does SMBG60CAHE3/52 meet automotive qualification standards?
Yes, SMBG60CAHE3/52 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88456, Revision: 09-Jan-2024). This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (HBM), validating its suitability for automotive powertrain, body electronics, and ADAS sensor modules.
What is the maximum clamping voltage of SMBG60CAHE3/52 under surge conditions?
The maximum clamping voltage (VC) of SMBG60CAHE3/52 is 96.8 V at a peak pulse current (IPPM) of 6.2 A, tested with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (-55 °C to +150 °C) and represents the upper limit of voltage seen by protected circuitry during worst-case transient events.
Can SMBG60CAHE3/52 be used in place of SMAJ60CA on the same PCB footprint?
No - SMBG60CAHE3/52 uses the SMBG (DO-215AA) package, which has different pad dimensions and terminal spacing than the SMA (DO-214AC) package of SMAJ60CA. The SMBG outline requires larger copper pads (0.2" × 0.2") and exhibits lower thermal resistance (RθJA = 100 °C/W vs. 140 °C/W), so direct footprint substitution would compromise solder joint reliability and thermal performance.
What does the "HE3" suffix indicate in SMBG60CAHE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It distinguishes SMBG60CAHE3/52 from non-automotive variants like SMBG60CA-E3 (RoHS, industrial grade only) and confirms full automotive process validation, including whisker resistance (JESD 201 Class 2) and moisture sensitivity level (MSL 1).
