Product details
Overview
SMAJ60C-E3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal or power lines. It features 60 V stand-off voltage (VWM), 107 V maximum clamping voltage (VC) at 3.7 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for protecting automotive sensor interfaces and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the SMAJ60C-E3/5A datasheet, SMAJ60C-E3/5A pinout, SMAJ60C-E3/5A application, or SMAJ60C-E3/5A equivalent, this page delivers verified electrical parameters, bi-directional terminal behavior, thermal resistance data, RoHS-compliant packaging details, and direct alternative part comparisons for circuit protection design-in.
Technical Context
The SMAJ60C-E3/5A operates as a bi-directional avalanche diode with symmetrical breakdown characteristics in both polarities, enabling suppression of positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable VBR (66.7–81.5 V) and low dynamic impedance under surge conditions.
Thermal performance is defined by RθJA = 120 °C/W (on 0.2 × 0.2" copper pads) and RθJL = 30 °C/W, supporting reliable operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 and JESD201 Class 1A whisker testing, confirming suitability for automated SMT assembly and high-reliability environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin below breakdown. |
| VC @ IPPM | 107 V - Clamped voltage across terminals during 3.7 A 10/1000 µs surge; determines protected circuit's maximum stress level. |
| IPPM | 3.7 A - Peak surge current capability under standard 10/1000 µs waveform; directly limits energy absorption capacity. |
| PPPM | 400 W - Peak pulse power rating at TA = 25 °C; derates above ambient per Fig. 2 in datasheet 88390. |
| VBR min/max | 66.7 V / 81.5 V - Breakdown voltage range at 1 mA test current; ensures consistent turn-on threshold across production lots. |
| ID @ VWM | 1.0 µA - Reverse leakage at rated stand-off voltage; critical for low-power sensor line integrity and battery drain control. |
| TJ range | −55 °C to +150 °C - Operating and storage junction temperature range; supports under-hood automotive and industrial ambient extremes. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking - both terminals are electrically symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional avalanche junction - conducts surge current equally in either direction when VWM is exceeded. |
| Cathode band (absent) | Polarity indicator | Not present on SMAJ60C-E3/5A; confirms bi-directional functionality and eliminates orientation-dependent placement errors. |
Key Features
| Feature | Design Value |

| Glass-passivated chip junction | Ensures long-term parameter stability and low leakage drift over temperature and lifetime, critical for automotive sensor reliability. |
| MSL Level 1, 260 °C reflow compatible | Supports single-pass lead-free reflow without preconditioning, reducing manufacturing complexity and cost. |
| RoHS-compliant, matte tin-plated leads | Meets J-STD-002 solderability and JESD22-B102 mechanical adhesion requirements for high-yield automated assembly. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns), improving protection margin for high-speed digital interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/5A | Same VWM, VC, and package; CA suffix denotes identical bi-directional specification per Vishay documentation. | No functional difference - CA and C suffixes are interchangeable per datasheet 88390 Section "DEVICES FOR BI-DIRECTION APPLICATIONS". | Select SMAJ60CA-E3/5A only if legacy BOM or distributor inventory mandates explicit CA marking; otherwise SMAJ60C-E3/5A is functionally identical. |
| SMCJ60CA | Higher PPPM (1500 W), larger DO-214AB (SMB) package, 100 V VC @ 12.3 A - not pin-compatible. | Used where higher energy handling is required (e.g., 48 V telecom power rails); requires PCB layout change due to larger footprint. | Choose SMCJ60CA only when surge threat exceeds 400 W; SMAJ60C-E3/5A remains optimal for space-constrained 24 V signal line protection. |
Compared with SMAJ60CA-E3/5A (identical spec), SMAJ60C-E3/5A offers identical protection performance in same DO-214AC footprint; versus SMCJ60CA, it trades lower surge rating for 40 % smaller board area and compatibility with fine-pitch SMT processes.

FAQ
What is the clamping voltage of SMAJ60C-E3/5A at its rated peak pulse current?
The SMAJ60C-E3/5A has a maximum clamping voltage (VC) of 107 V when subjected to its rated peak pulse current (IPPM) of 3.7 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 3 of Vishay document 88390 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMAJ60C-E3/5A maintains this clamping performance across its full operating temperature range.
Is SMAJ60C-E3/5A unidirectional or bidirectional, and how is polarity indicated?
SMAJ60C-E3/5A is a bi-directional transient voltage suppressor, meaning it provides symmetrical clamping for both positive and negative transients. As confirmed in the "DEVICES FOR BI-DIRECTION APPLICATIONS" section of Vishay datasheet 88390, bi-directional types like SMAJ60C-E3/5A have no cathode band marking - both terminals are functionally identical. This eliminates orientation errors during automated placement and simplifies PCB layout for differential or AC-coupled lines.
What is the maximum operating temperature and thermal resistance of SMAJ60C-E3/5A?
The SMAJ60C-E3/5A supports an operating junction temperature range of −55 °C to +150 °C. Its thermal resistance from junction to ambient (RθJA) is 120 °C/W when mounted on the recommended 0.2 × 0.2" (5.0 × 5.0 mm) copper pads, and junction-to-lead (RθJL) is 30 °C/W. These values are specified in the "THERMAL CHARACTERISTICS" table on page 4 of Vishay document 88390 and are essential for calculating safe power dissipation margins in sealed or high-ambient environments.
Does SMAJ60C-E3/5A meet automotive qualification standards?
SMAJ60C-E3/5A carries the "E3" suffix, indicating RoHS compliance and commercial-grade qualification. While it shares the same die and construction as AEC-Q101 qualified parts (e.g., SMAJ60CHE3 variants), the SMAJ60C-E3/5A itself is not AEC-Q101 certified. For automotive applications requiring formal qualification, engineers should specify the HE3-suffixed version; SMAJ60C-E3/5A remains suitable for non-safety-critical industrial and consumer systems per its documented reliability testing.
What is the reverse leakage current of SMAJ60C-E3/5A at its stand-off voltage?
The SMAJ60C-E3/5A exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 60 V, as specified in the "ELECTRICAL CHARACTERISTICS" table on page 3 of Vishay document 88390. This low leakage ensures minimal impact on high-impedance sensor circuits and battery-powered devices, preserving signal accuracy and extending operational life without introducing parasitic loading.
